# Class
public final class **Class** extends [Object](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Object.html)
implements [Serializable](https://developers.google.com/j2objc/javadoc/jre/reference/java/io/Serializable.html) [GenericDeclaration](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/GenericDeclaration.html) [Type](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Type.html) [AnnotatedElement](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/AnnotatedElement.html) Instances of the class `Class` represent classes and
interfaces in a running Java application. An enum is a kind of
class and an annotation is a kind of interface. Every array also
belongs to a class that is reflected as a `Class` object
that is shared by all arrays with the same element type and number
of dimensions. The primitive Java types (`boolean`,
`byte`, `char`, `short`,
`int`, `long`, `float`, and
`double`), and the keyword `void` are also
represented as `Class` objects.
`Class` has no public constructor. Instead `Class`
objects are constructed automatically by the Java Virtual Machine as classes
are loaded and by calls to the `defineClass` method in the class
loader.
The following example uses a `Class` object to print the
class name of an object:
> ```
> void printClassName(Object obj) {
> System.out.println("The class of " + obj +
> " is " + obj.getClass().getName());
> }
>
> ```
It is also possible to get the `Class` object for a named
type (or for void) using a class literal. See Section 15.8.2 of
The Java™ Language Specification.
For example:
> `System.out.println("The name of class Foo is: "+Foo.class.getName());`

**asSubclass**
([Class](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\ clazz)
Casts this `Class` object to represent a subclass of the class
represented by the specified class object. Checks that the cast
is valid, and throws a `ClassCastException` if it is not. If
this method succeeds, it always returns a reference to this class object.
This method is useful when a client needs to "narrow" the type of
a `Class` object to pass it to an API that restricts the
`Class` objects that it is willing to accept. A cast would
generate a compile-time warning, as the correctness of the cast
could not be checked at runtime (because generic types are implemented
by erasure).
##### Parameters
| clazz | the class of the type to cast this class object to |
|---|---|
##### Returns
- this `Class` object, cast to represent a subclass of the specified class object.
##### Throws
| [ClassCastException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ClassCastException.html) | if this `Class` object does not represent a subclass of the specified class (here "subclass" includes the class itself). |
|---|---|
#### public T
**cast**
([Object](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Object.html) obj)
Casts an object to the class or interface represented
by this `Class` object.
##### Parameters
| obj | the object to be cast |
|---|---|
##### Returns
- the object after casting, or null if obj is null
##### Throws
| [ClassCastException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ClassCastException.html) | if the object is not null and is not assignable to the type T. |
|---|---|
#### public boolean
**desiredAssertionStatus**
()
Returns the assertion status that would be assigned to this
class if it were to be initialized at the time this method is invoked.
If this class has had its assertion status set, the most recent
setting will be returned; otherwise, if any package default assertion
status pertains to this class, the most recent setting for the most
specific pertinent package default assertion status is returned;
otherwise, if this class is not a system class (i.e., it has a
class loader) its class loader's default assertion status is returned;
otherwise, the system class default assertion status is returned.
Few programmers will have any need for this method; it is provided
for the benefit of the JRE itself. (It allows a class to determine at
the time that it is initialized whether assertions should be enabled.)
Note that this method is not guaranteed to return the actual
assertion status that was (or will be) associated with the specified
class when it was (or will be) initialized.
##### Returns
- the desired assertion status of the specified class.

#### public static [Class](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\
**forName**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) name, boolean initialize, [ClassLoader](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ClassLoader.html) loader)
Returns the `Class` object associated with the class or
interface with the given string name, using the given class loader.
Given the fully qualified name for a class or interface (in the same
format returned by `getName`) this method attempts to
locate, load, and link the class or interface. The specified class
loader is used to load the class or interface. If the parameter
`loader` is null, the class is loaded through the bootstrap
class loader. The class is initialized only if the
`initialize` parameter is `true` and if it has
not been initialized earlier.
If `name` denotes a primitive type or void, an attempt
will be made to locate a user-defined class in the unnamed package whose
name is `name`. Therefore, this method cannot be used to
obtain any of the `Class` objects representing primitive
types or void.
If `name` denotes an array class, the component type of
the array class is loaded but not initialized.
For example, in an instance method the expression:
> `Class.forName("Foo")`
is equivalent to: `Class.forName("Foo", true, this.getClass().getClassLoader())`
Note that this method throws errors related to loading, linking or initializing as specified in Sections 12.2, 12.3 and 12.4 of *The
Java Language Specification* . Note that this method does not check whether the requested class is accessible to its caller.
If the `loader` is `null`, and a security
manager is present, and the caller's class loader is not null, then this
method calls the security manager's `checkPermission` method
with a `RuntimePermission("getClassLoader")` permission to
ensure it's ok to access the bootstrap class loader.
##### Parameters
| name | fully qualified name of the desired class |
| initialize | if `true` the class will be initialized. See Section 12.4 of *The Java Language Specification*. |
| loader | class loader from which the class must be loaded |
|---|---|
##### Returns
- class object representing the desired class
##### Throws
| [LinkageError](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/LinkageError.html) | if the linkage fails |
| [ExceptionInInitializerError](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ExceptionInInitializerError.html) | if the initialization provoked by this method fails |
| [ClassNotFoundException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ClassNotFoundException.html) | if the class cannot be located by the specified class loader |
|---|---|

#### public static [Class](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\
**forName**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) className)
Returns the `Class` object associated with the class or
interface with the given string name. Invoking this method is
equivalent to:
> `Class.forName(className, true, currentLoader)`
where `currentLoader` denotes the defining class loader of the current class.
For example, the following code fragment returns the
runtime `Class` descriptor for the class named
`java.lang.Thread`:
> `Class t = Class.forName("java.lang.Thread")`
A call to `forName("X")` causes the class named
`X` to be initialized.
##### Parameters
| className | the fully qualified name of the desired class. |
|---|---|
##### Returns
- the `Class` object for the class with the specified name.
##### Throws
| [LinkageError](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/LinkageError.html) | if the linkage fails |
| [ExceptionInInitializerError](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ExceptionInInitializerError.html) | if the initialization provoked by this method fails |
| [ClassNotFoundException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ClassNotFoundException.html) | if the class cannot be located |

#### public [Annotation\[\]](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/annotation/Annotation.html)
**getAnnotations**
()
Returns annotations that are *present* on this element.
If there are no annotations *present* on this element, the return
value is an array of length 0.
The caller of this method is free to modify the returned array; it will
have no effect on the arrays returned to other callers.
##### Returns
- annotations present on this element
#### public A\[\]

#### public [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**getCanonicalName**
()
Returns the canonical name of the underlying class as
defined by the Java Language Specification. Returns null if
the underlying class does not have a canonical name (i.e., if
it is a local or anonymous class or an array whose component
type does not have a canonical name).
##### Returns
- the canonical name of the underlying class if it exists, and `null` otherwise.
#### public [ClassLoader](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ClassLoader.html)
**getClassLoader**
()
Returns the class loader for the class. Some implementations may use
null to represent the bootstrap class loader. This method will return
null in such implementations if this class was loaded by the bootstrap
class loader.
If a security manager is present, and the caller's class loader is
not null and the caller's class loader is not the same as or an ancestor of
the class loader for the class whose class loader is requested, then
this method calls the security manager's `checkPermission`
method with a `RuntimePermission("getClassLoader")`
permission to ensure it's ok to access the class loader for the class.
If this object
represents a primitive type or void, null is returned.
##### Returns
- the class loader that loaded the class or interface represented by this object.
##### Throws
| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | if a security manager exists and its `checkPermission` method denies access to the class loader for the class. |

#### public [Class\[\]](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\
**getClasses**
()
Returns an array containing `Class` objects representing all
the public classes and interfaces that are members of the class
represented by this `Class` object. This includes public
class and interface members inherited from superclasses and public class
and interface members declared by the class. This method returns an
array of length 0 if this `Class` object has no public member
classes or interfaces. This method also returns an array of length 0 if
this `Class` object represents a primitive type, an array
class, or void.
##### Returns
- the array of `Class` objects representing the public members of this class
#### public [Class](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\
**getComponentType**
()
Returns the `Class` representing the component type of an
array. If this class does not represent an array class this method
returns null.
##### Returns
- the `Class` representing the component type of this class if this class is an array
##### See Also
- `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Array.html`
#### public [Constructor](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Constructor.html)\
**getConstructor**
([Class...](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\ parameterTypes)
Returns a `Constructor` object that reflects the specified
public constructor of the class represented by this `Class`
object. The `parameterTypes` parameter is an array of
`Class` objects that identify the constructor's formal
parameter types, in declared order.
If this `Class` object represents an inner class
declared in a non-static context, the formal parameter types
include the explicit enclosing instance as the first parameter.
The constructor to reflect is the public constructor of the class
represented by this `Class` object whose formal parameter
types match those specified by `parameterTypes`.
##### Parameters
| parameterTypes | the parameter array |
|---|---|
##### Returns
- the `Constructor` object of the public constructor that matches the specified `parameterTypes`
##### Throws
| [NoSuchMethodException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NoSuchMethodException.html) | if a matching method is not found. |
| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | If a security manager, *s*, is present and the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityManager.html#checkPackageAccess(java.lang.String)` denies access to the package of this class. |
|---|---|
#### public [Constructor\[\]](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Constructor.html)\
**getConstructors**
()
Returns an array containing `Constructor` objects reflecting
all the public constructors of the class represented by this
`Class` object. An array of length 0 is returned if the
class has no public constructors, or if the class is an array class, or
if the class reflects a primitive type or void.
Note that while this method returns an array of `Constructor` objects (that is an array of constructors from
this class), the return type of this method is `Constructor[]` and *not* `Constructor[]` as
might be expected. This less informative return type is
necessary since after being returned from this method, the
array could be modified to hold `Constructor` objects for
different classes, which would violate the type guarantees of
`Constructor[]`.
##### Returns
- the array of `Constructor` objects representing the public constructors of this class
##### Throws
| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | If a security manager, *s*, is present and the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityManager.html#checkPackageAccess(java.lang.String)` denies access to the package of this class. |

If this `Class` object represents a local or anonymous
class within a method, returns a `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Method.html` object representing the
immediately enclosing method of the underlying class. Returns
`null` otherwise.
In particular, this method returns `null` if the underlying
class is a local or anonymous class immediately enclosed by a type
declaration, instance initializer or static initializer.
##### Returns
- the immediately enclosing method of the underlying class, if that class is a local or anonymous class; otherwise `null`.
#### public T\[\]
**getEnumConstants**
()
Returns the elements of this enum class or null if this
Class object does not represent an enum type.
##### Returns
- an array containing the values comprising the enum class represented by this Class object in the order they're declared, or null if this Class object does not represent an enum type
#### public [Field](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Field.html)
**getField**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) name)
Returns a `Field` object that reflects the specified public member
field of the class or interface represented by this `Class`
object. The `name` parameter is a `String` specifying the
simple name of the desired field.
The field to be reflected is determined by the algorithm that
follows. Let C be the class or interface represented by this object:
1. If C declares a public field with the name specified, that is the field to be reflected.
2. If no field was found in step 1 above, this algorithm is applied recursively to each direct superinterface of C. The direct superinterfaces are searched in the order they were declared.
3. If no field was found in steps 1 and 2 above, and C has a superclass S, then this algorithm is invoked recursively upon S. If C has no superclass, then a `NoSuchFieldException` is thrown.
If this `Class` object represents an array type, then this
method does not find the `length` field of the array type.
##### Parameters
| name | the field name |
|---|---|
##### Returns
- the `Field` object of this class specified by `name`
##### Throws
| [NoSuchFieldException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NoSuchFieldException.html) | if a field with the specified name is not found. |
| [NullPointerException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NullPointerException.html) | if `name` is `null` |
| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | If a security manager, *s*, is present and the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityManager.html#checkPackageAccess(java.lang.String)` denies access to the package of this class. |
|---|---|
#### public [Field\[\]](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Field.html)
**getFields**
()
Returns an array containing `Field` objects reflecting all
the accessible public fields of the class or interface represented by
this `Class` object.
If this `Class` object represents a class or interface with no
no accessible public fields, then this method returns an array of length
0.
If this `Class` object represents a class, then this method
returns the public fields of the class and of all its superclasses.
If this `Class` object represents an interface, then this
method returns the fields of the interface and of all its
superinterfaces.
If this `Class` object represents an array type, a primitive
type, or void, then this method returns an array of length 0.
The elements in the returned array are not sorted and are not in any
particular order.
##### Returns
- the array of `Field` objects representing the public fields
##### Throws
| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | If a security manager, *s*, is present and the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityManager.html#checkPackageAccess(java.lang.String)` denies access to the package of this class. |
|---|---|
#### public [Type\[\]](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Type.html)
**getGenericInterfaces**
()
Returns the `Type`s representing the interfaces
directly implemented by the class or interface represented by
this object.
If a superinterface is a parameterized type, the
`Type` object returned for it must accurately reflect
the actual type parameters used in the source code. The
parameterized type representing each superinterface is created
if it had not been created before. See the declaration of
`https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/ParameterizedType.html`
for the semantics of the creation process for parameterized
types.
If this object represents a class, the return value is an
array containing objects representing all interfaces
implemented by the class. The order of the interface objects in
the array corresponds to the order of the interface names in
the `implements` clause of the declaration of the class
represented by this object. In the case of an array class, the
interfaces `Cloneable` and `Serializable` are
returned in that order.
If this object represents an interface, the array contains
objects representing all interfaces directly extended by the
interface. The order of the interface objects in the array
corresponds to the order of the interface names in the
`extends` clause of the declaration of the interface
represented by this object.
If this object represents a class or interface that
implements no interfaces, the method returns an array of length
0.
If this object represents a primitive type or void, the
method returns an array of length 0.
##### Returns
- an array of interfaces implemented by this class
##### Throws
| [GenericSignatureFormatError](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/GenericSignatureFormatError.html) | if the generic class signature does not conform to the format specified in The Java™ Virtual Machine Specification |
| [TypeNotPresentException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/TypeNotPresentException.html) | if any of the generic superinterfaces refers to a non-existent type declaration |
| [MalformedParameterizedTypeException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/MalformedParameterizedTypeException.html) | if any of the generic superinterfaces refer to a parameterized type that cannot be instantiated for any reason |
|---|---|
#### public [Type](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Type.html)
**getGenericSuperclass**
()
Returns the `Type` representing the direct superclass of
the entity (class, interface, primitive type or void) represented by
this `Class`.
If the superclass is a parameterized type, the `Type`
object returned must accurately reflect the actual type
parameters used in the source code. The parameterized type
representing the superclass is created if it had not been
created before. See the declaration of `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/ParameterizedType.html` for the
semantics of the creation process for parameterized types. If
this `Class` represents either the `Object`
class, an interface, a primitive type, or void, then null is
returned. If this object represents an array class then the
`Class` object representing the `Object` class is
returned.
##### Returns
- the superclass of the class represented by this object
##### Throws
| [GenericSignatureFormatError](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/GenericSignatureFormatError.html) | if the generic class signature does not conform to the format specified in The Java™ Virtual Machine Specification |

|---|---|
#### public [Class\[\]](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\
**getInterfaces**
()
Determines the interfaces implemented by the class or interface
represented by this object.
If this object represents a class, the return value is an array
containing objects representing all interfaces implemented by the
class. The order of the interface objects in the array corresponds to
the order of the interface names in the `implements` clause
of the declaration of the class represented by this object. For
example, given the declaration:
> `class Shimmer implements FloorWax, DessertTopping { ... }`
suppose the value of `s` is an instance of `Shimmer`; the value of the expression: `s.getClass().getInterfaces()[0]`
is the `Class` object that represents interface `FloorWax`; and the value of: `s.getClass().getInterfaces()[1]`
is the `Class` object that represents interface `DessertTopping`.
If this object represents an interface, the array contains objects
representing all interfaces extended by the interface. The order of the
interface objects in the array corresponds to the order of the interface
names in the `extends` clause of the declaration of the
interface represented by this object.
If this object represents a class or interface that implements no
interfaces, the method returns an array of length 0.
If this object represents a primitive type or void, the method
returns an array of length 0.
If this `Class` object represents an array type, the
interfaces `Cloneable` and `java.io.Serializable` are
returned in that order.
##### Returns
- an array of interfaces implemented by this class.
#### public [Method](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Method.html)
**getMethod**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) name, [Class...](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\ parameterTypes)
Returns a `Method` object that reflects the specified public
member method of the class or interface represented by this
`Class` object. The `name` parameter is a
`String` specifying the simple name of the desired method. The
`parameterTypes` parameter is an array of `Class`
objects that identify the method's formal parameter types, in declared
order. If `parameterTypes` is `null`, it is
treated as if it were an empty array.
If the `name` is "``" or "``" a
`NoSuchMethodException` is raised. Otherwise, the method to
be reflected is determined by the algorithm that follows. Let C be the
class or interface represented by this object:
1. C is searched for a *matching method*, as defined below. If a matching method is found, it is reflected.
2. If no matching method is found by step 1 then:
1. If C is a class other than `Object`, then this algorithm is invoked recursively on the superclass of C.
2. If C is the class `Object`, or if C is an interface, then the superinterfaces of C (if any) are searched for a matching method. If any such method is found, it is reflected.
To find a matching method in a class or interface C: If C
declares exactly one public method with the specified name and exactly
the same formal parameter types, that is the method reflected. If more
than one such method is found in C, and one of these methods has a
return type that is more specific than any of the others, that method is
reflected; otherwise one of the methods is chosen arbitrarily.
Note that there may be more than one matching method in a
class because while the Java language forbids a class to
declare multiple methods with the same signature but different
return types, the Java virtual machine does not. This
increased flexibility in the virtual machine can be used to
implement various language features. For example, covariant
returns can be implemented with {@linkplain java.lang.reflect.Method#isBridge bridge methods}; the bridge
method and the method being overridden would have the same
signature but different return types.
If this `Class` object represents an array type, then this
method does not find the `clone()` method.
Static methods declared in superinterfaces of the class or interface
represented by this `Class` object are not considered members of
the class or interface.
##### Parameters
| name | the name of the method |
| parameterTypes | the list of parameters |
|---|---|
##### Returns
- the `Method` object that matches the specified `name` and `parameterTypes`
##### Throws
| [NoSuchMethodException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NoSuchMethodException.html) | if a matching method is not found or if the name is "\"or "\". |
| [NullPointerException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NullPointerException.html) | if `name` is `null` |
| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | If a security manager, *s*, is present and the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityManager.html#checkPackageAccess(java.lang.String)` denies access to the package of this class. |
|---|---|
#### public [Method\[\]](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Method.html)
**getMethods**
()
Returns an array containing `Method` objects reflecting all the
public methods of the class or interface represented by this `Class` object, including those declared by the class or interface and
those inherited from superclasses and superinterfaces.
If this `Class` object represents a type that has multiple
public methods with the same name and parameter types, but different
return types, then the returned array has a `Method` object for
each such method.
If this `Class` object represents a type with a class
initialization method ``, then the returned array does
*not* have a corresponding `Method` object.
If this `Class` object represents an array type, then the
returned array has a `Method` object for each of the public
methods inherited by the array type from `Object`. It does not
contain a `Method` object for `clone()`.
If this `Class` object represents an interface then the
returned array does not contain any implicitly declared methods from
`Object`. Therefore, if no methods are explicitly declared in
this interface or any of its superinterfaces then the returned array
has length 0. (Note that a `Class` object which represents a class
always has public methods, inherited from `Object`.)
If this `Class` object represents a primitive type or void,
then the returned array has length 0.
Static methods declared in superinterfaces of the class or interface
represented by this `Class` object are not considered members of
the class or interface.
The elements in the returned array are not sorted and are not in any
particular order.
##### Returns
- the array of `Method` objects representing the public methods of this class
##### Throws
| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | If a security manager, *s*, is present and the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityManager.html#checkPackageAccess(java.lang.String)` denies access to the package of this class. |
|---|---|
#### public int
**getModifiers**
()
Returns the Java language modifiers for this class or interface, encoded
in an integer. The modifiers consist of the Java Virtual Machine's
constants for `public`, `protected`,
`private`, `final`, `static`,
`abstract` and `interface`; they should be decoded
using the methods of class `Modifier`.
If the underlying class is an array class, then its
`public`, `private` and `protected`
modifiers are the same as those of its component type. If this
`Class` represents a primitive type or void, its
`public` modifier is always `true`, and its
`protected` and `private` modifiers are always
`false`. If this object represents an array class, a
primitive type or void, then its `final` modifier is always
`true` and its interface modifier is always
`false`. The values of its other modifiers are not determined
by this specification.
The modifier encodings are defined in *The Java Virtual Machine
Specification*, table 4.1.
##### Returns
- the `int` representing the modifiers for this class
##### See Also
- `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Modifier.html`
#### public [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**getName**
()
Returns the name of the entity (class, interface, array class,
primitive type, or void) represented by this `Class` object,
as a `String`.
If this class object represents a reference type that is not an
array type then the binary name of the class is returned, as specified
by
The Java™ Language Specification.
If this class object represents a primitive type or void, then the
name returned is a `String` equal to the Java language
keyword corresponding to the primitive type or void.
If this class object represents a class of arrays, then the internal
form of the name consists of the name of the element type preceded by
one or more '`[`' characters representing the depth of the array
nesting. The encoding of element type names is as follows:
> | Element Type | | Encoding |
> |---|---|---|
> | boolean | | Z |
> | byte | | B |
> | char | | C |
> | class or interface | | L*classname*; |
> | double | | D |
> | float | | F |
> | int | | I |
> | long | | J |
> | short | | S |
The class or interface name *classname* is the binary name of
the class specified above.
Examples:
>
> ```
> String.class.getName()
> returns "java.lang.String"
> byte.class.getName()
> returns "byte"
> (new Object[3]).getClass().getName()
> returns "[Ljava.lang.Object;"
> (new int[3][4][5][6][7][8][9]).getClass().getName()
> returns "[[[[[[[I"
>
> ```
##### Returns
- the name of the class or interface represented by this object.
#### public [Package](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Package.html)
**getPackage**
()
Gets the package for this class. The class loader of this class is used
to find the package. If the class was loaded by the bootstrap class
loader the set of packages loaded from CLASSPATH is searched to find the
package of the class. Null is returned if no package object was created
by the class loader of this class.
Packages have attributes for versions and specifications only if the
information was defined in the manifests that accompany the classes, and
if the class loader created the package instance with the attributes
from the manifest.
##### Returns
- the package of the class, or null if no package information is available from the archive or codebase.
#### public [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**getPackageName**
()
Returns the fully qualified package name.
If this class is a top level class, then this method returns the fully
qualified name of the package that the class is a member of, or the
empty string if the class is in an unnamed package.
If this class is a member class, then this method is equivalent to
invoking `getPackageName()` on the {@linkplain #getEnclosingClass
enclosing class}.
If this class is a {@linkplain #isLocalClass local class} or an {@linkplain #isAnonymousClass() anonymous class}, then this method is equivalent to
invoking `getPackageName()` on the {@linkplain #getDeclaringClass
declaring class} of the {@linkplain #getEnclosingMethod enclosing method} or
{@linkplain #getEnclosingConstructor enclosing constructor}.
If this class represents an array type then this method returns the
package name of the element type. If this class represents a primitive
type or void then the package name "`java.lang`" is returned.
##### Returns
- the fully qualified package name
#### public [ProtectionDomain](https://developers.google.com/j2objc/javadoc/jre/reference/java/security/ProtectionDomain.html)
**getProtectionDomain**
()
Returns the `ProtectionDomain` of this class. If there is a
security manager installed, this method first calls the security
manager's `checkPermission` method with a
`RuntimePermission("getProtectionDomain")` permission to
ensure it's ok to get the
`ProtectionDomain`.
##### Returns
- the ProtectionDomain of this class
##### Throws
| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | if a security manager exists and its `checkPermission` method doesn't allow getting the ProtectionDomain. |

**getResource**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) name)
Finds a resource with a given name. The rules for searching resources
associated with a given class are implemented by the defining
{@linkplain ClassLoader class loader} of the class. This method
delegates to this object's class loader. If this object was loaded by
the bootstrap class loader, the method delegates to `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ClassLoader.html#getSystemResource(java.lang.String)`.
Before delegation, an absolute resource name is constructed from the
given resource name using this algorithm:
- If the `name` begins with a `'/'` ('\\u002f'), then the absolute name of the resource is the portion of the `name` following the `'/'`.
- Otherwise, the absolute name is of the following form: `modified_package_name/name`
Where the `modified_package_name` is the package name of this
object with `'/'` substituted for `'.'`
('\\u002e').
##### Parameters
| name | name of the desired resource |
|---|---|
##### Returns
- A `https://developers.google.com/j2objc/javadoc/jre/reference/java/net/URL.html` object or `null` if no resource with this name is found

**getResourceAsStream**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) name)
Finds a resource with a given name. The rules for searching resources
associated with a given class are implemented by the defining
{@linkplain ClassLoader class loader} of the class. This method
delegates to this object's class loader. If this object was loaded by
the bootstrap class loader, the method delegates to `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ClassLoader.html#getSystemResourceAsStream(java.lang.String)`.
Before delegation, an absolute resource name is constructed from the
given resource name using this algorithm:
- If the `name` begins with a `'/'` ('\\u002f'), then the absolute name of the resource is the portion of the `name` following the `'/'`.
- Otherwise, the absolute name is of the following form: `modified_package_name/name`
Where the `modified_package_name` is the package name of this
object with `'/'` substituted for `'.'`
('\\u002e').
##### Parameters
| name | name of the desired resource |
|---|---|
##### Returns
- A `https://developers.google.com/j2objc/javadoc/jre/reference/java/io/InputStream.html` object or `null` if no resource with this name is found

**getSimpleName**
()
Returns the simple name of the underlying class as given in the
source code. Returns an empty string if the underlying class is
anonymous.
The simple name of an array is the simple name of the
component type with "\[\]" appended. In particular the simple
name of an array whose component type is anonymous is "\[\]".
##### Returns
- the simple name of the underlying class
#### public [Class](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\
**getSuperclass**
()
Returns the `Class` representing the superclass of the entity
(class, interface, primitive type or void) represented by this
`Class`. If this `Class` represents either the
`Object` class, an interface, a primitive type, or void, then
null is returned. If this object represents an array class then the
`Class` object representing the `Object` class is
returned.

#### public boolean
**isAnnotation**
()
Returns true if this `Class` object represents an annotation
type. Note that if this method returns true, `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html#isInterface()`
would also return true, as all annotation types are also interfaces.
##### Returns
- `true` if this class object represents an annotation type; `false` otherwise
#### public boolean
**isAnnotationPresent**
([Class](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\ annotationType)
Returns true if an annotation for the specified type
is *present* on this element, else false. This method
is designed primarily for convenient access to marker annotations.
The truth value returned by this method is equivalent to:
`getAnnotation(annotationClass) != null`
The body of the default method is specified to be the code
above.
##### Parameters

- `true` if this object represents an array class; `false` otherwise.
#### public boolean
**isAssignableFrom**
([Class](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\ cls)
Determines if the class or interface represented by this
`Class` object is either the same as, or is a superclass or
superinterface of, the class or interface represented by the specified
`Class` parameter. It returns `true` if so;
otherwise it returns `false`. If this `Class`
object represents a primitive type, this method returns
`true` if the specified `Class` parameter is
exactly this `Class` object; otherwise it returns
`false`.
Specifically, this method tests whether the type represented by the
specified `Class` parameter can be converted to the type
represented by this `Class` object via an identity conversion
or via a widening reference conversion. See *The Java Language
Specification*, sections 5.1.1 and 5.1.4 , for details.
##### Parameters
| cls | the `Class` object to be checked |
|---|---|
##### Returns
- the `boolean` value indicating whether objects of the type `cls` can be assigned to objects of this class
##### Throws
| [NullPointerException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NullPointerException.html) | if the specified Class parameter is null. |
|---|---|
#### public boolean
**isEnum**
()
Returns true if and only if this class was declared as an enum in the
source code.
##### Returns
- true if and only if this class was declared as an enum in the source code
#### public boolean
**isInstance**
([Object](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Object.html) obj)
Determines if the specified `Object` is assignment-compatible
with the object represented by this `Class`. This method is
the dynamic equivalent of the Java language `instanceof`
operator. The method returns `true` if the specified
`Object` argument is non-null and can be cast to the
reference type represented by this `Class` object without
raising a `ClassCastException.` It returns `false`
otherwise.
Specifically, if this `Class` object represents a
declared class, this method returns `true` if the specified
`Object` argument is an instance of the represented class (or
of any of its subclasses); it returns `false` otherwise. If
this `Class` object represents an array class, this method
returns `true` if the specified `Object` argument
can be converted to an object of the array class by an identity
conversion or by a widening reference conversion; it returns
`false` otherwise. If this `Class` object
represents an interface, this method returns `true` if the
class or any superclass of the specified `Object` argument
implements this interface; it returns `false` otherwise. If
this `Class` object represents a primitive type, this method
returns `false`.
##### Parameters
| obj | the object to check |
|---|---|
##### Returns
- true if `obj` is an instance of this class
#### public boolean
**isInterface**
()
Determines if the specified `Class` object represents an
interface type.
##### Returns
- `true` if this object represents an interface; `false` otherwise.
#### public boolean
**isLocalClass**
()
Returns `true` if and only if the underlying class
is a local class.
##### Returns
- `true` if and only if this class is a local class.
#### public boolean
**isMemberClass**
()
Returns `true` if and only if the underlying class
is a member class.
##### Returns
- `true` if and only if this class is a member class.
#### public boolean
**isPrimitive**
()
Determines if the specified `Class` object represents a
primitive type.
There are nine predefined `Class` objects to represent
the eight primitive types and void. These are created by the Java
Virtual Machine, and have the same names as the primitive types that
they represent, namely `boolean`, `byte`,
`char`, `short`, `int`,
`long`, `float`, and `double`.
These objects may only be accessed via the following public static
final variables, and are the only `Class` objects for which
this method returns `true`.
##### Returns
- true if and only if this class represents a primitive type

#### public boolean
**isSynthetic**
()
Returns `true` if this class is a synthetic class;
returns `false` otherwise.
##### Returns
- `true` if and only if this class is a synthetic class as defined by the Java Language Specification.
#### public T
**newInstance**
()
Creates a new instance of the class represented by this `Class`
object. The class is instantiated as if by a `new`
expression with an empty argument list. The class is initialized if it
has not already been initialized.
Note that this method propagates any exception thrown by the
nullary constructor, including a checked exception. Use of
this method effectively bypasses the compile-time exception
checking that would otherwise be performed by the compiler.
The `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Constructor.html#newInstance(java.lang.Object...)` method avoids this problem by wrapping
any exception thrown by the constructor in a (checked) `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/InvocationTargetException.html`.
##### Returns
- a newly allocated instance of the class represented by this object.
##### Throws
| [IllegalAccessException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/IllegalAccessException.html) | if the class or its nullary constructor is not accessible. |
| [InstantiationException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/InstantiationException.html) | if this `Class` represents an abstract class, an interface, an array class, a primitive type, or void; or if the class has no nullary constructor; or if the instantiation fails for some other reason. |
| [ExceptionInInitializerError](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ExceptionInInitializerError.html) | if the initialization provoked by this method fails. |
| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | If a security manager, *s*, is present and the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityManager.html#checkPackageAccess(java.lang.String)` denies access to the package of this class. |

#### public [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**toGenericString**
()
Returns a string describing this `Class`, including
information about modifiers and type parameters.
The string is formatted as a list of type modifiers, if any,
followed by the kind of type (empty string for primitive types
and `class`, `enum`, `interface`, or
`@``interface`, as appropriate), followed
by the type's name, followed by an angle-bracketed
comma-separated list of the type's type parameters, if any.
A space is used to separate modifiers from one another and to
separate any modifiers from the kind of type. The modifiers
occur in canonical order. If there are no type parameters, the
type parameter list is elided.
Note that since information about the runtime representation
of a type is being generated, modifiers not present on the
originating source code or illegal on the originating source
code may be present.
##### Returns
- a string describing this `Class`, including information about modifiers and type parameters
#### public [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**toString**
()
Converts the object to a string. The string representation is the
string "class" or "interface", followed by a space, and then by the
fully qualified name of the class in the format returned by
`getName`. If this `Class` object represents a
primitive type, this method returns the name of the primitive type. If
this `Class` object represents void this method returns
"void".
##### Returns
- a string representation of this class object.
