# Constructor

public final class **Constructor** extends [Executable](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/Executable.html)  
`Constructor` provides information about, and access to, a single
constructor for a class.

`Constructor` permits widening conversions to occur when matching the
actual parameters to newInstance() with the underlying
constructor's formal parameters, but throws an
`IllegalArgumentException` if a narrowing conversion would occur.

## Public Methods

#### public boolean
**equals**
([Object](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Object.html) obj)

Compares this `Constructor` against the specified object.
Returns true if the objects are the same. Two `Constructor` objects are
the same if they were declared by the same class and have the
same formal parameter types.

##### Parameters

| obj | the object to compare this instance with. |
|---|---|

##### Returns

- `true` if the specified object is equal to this `Object`; `false` otherwise.

#### public AnnotatedType
**getAnnotatedReturnType**
()

Returns an `AnnotatedType` object that represents the use of a type to
specify the return type of the method/constructor represented by this
Executable.

If this `Executable` object represents a constructor, the `AnnotatedType` object represents the type of the constructed object.

If this `Executable` object represents a method, the `AnnotatedType` object represents the use of a type to specify the return
type of the method.

##### Returns

- an object representing the return type of the method or constructor represented by this `Executable`

#### public T
**getAnnotation**
([Class](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Class.html)\<T\> annotationClass)

Returns this element's annotation for the specified type if
such an annotation is *present*, else null.

##### Parameters

| annotationClass | the Class object corresponding to the annotation type |

This method ignores inherited annotations.

If there are no annotations *directly 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 directly present on this element

**getGenericParameterTypes**
()

Returns an array of `Type` objects that represent the formal
parameter types, in declaration order, of the executable represented by
this object. Returns an array of length 0 if the
underlying executable takes no parameters.

If a formal parameter type is a parameterized type,
the `Type` object returned for it must accurately reflect
the actual type parameters used in the source code.

If a formal parameter type is a type variable or a parameterized
type, it is created. Otherwise, it is resolved.

#### public int
**getModifiers**
()

Returns the Java language {@linkplain Modifier modifiers} for
the executable represented by this object.

- the Java language modifiers for the underlying member

#### public [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**getName**
()

Returns the name of this constructor, as a string. This is
the binary name of the constructor's declaring class.

#### public [Annotation\[\]\[\]](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/annotation/Annotation.html)
**getParameterAnnotations**
()

Returns an array of arrays of `Annotation`s that
represent the annotations on the formal parameters, in
declaration order, of the `Executable` represented by
this object. Synthetic and mandated parameters (see
explanation below), such as the outer "this" parameter to an
inner class constructor will be represented in the returned
array. If the executable has no parameters (meaning no formal,
no synthetic, and no mandated parameters), a zero-length array
will be returned. If the `Executable` has one or more
parameters, a nested array of length zero is returned for each
parameter with no annotations. The annotation objects contained
in the returned arrays are serializable. The caller of this
method is free to modify the returned arrays; it will have no
effect on the arrays returned to other callers.

A compiler may add extra parameters that are implicitly
declared in source ("mandated"), as well as parameters that
are neither implicitly nor explicitly declared in source
("synthetic") to the parameter list for a method. See Parameter for more information.

##### Returns

- an array of arrays that represent the annotations on the formal and implicit parameters, in declaration order, of the executable represented by this object

#### public int
**getParameterCount**

#### public T
**newInstance**
([Object...](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Object.html) initargs)

Uses the constructor represented by this `Constructor` object to
create and initialize a new instance of the constructor's
declaring class, with the specified initialization parameters.
Individual parameters are automatically unwrapped to match
primitive formal parameters, and both primitive and reference
parameters are subject to method invocation conversions as necessary.

If the number of formal parameters required by the underlying constructor
is 0, the supplied `initargs` array may be of length 0 or null.

If the constructor's declaring class is an inner class in a
non-static context, the first argument to the constructor needs
to be the enclosing instance; see section 15.9.3 of
The Java™ Language Specification.

If the required access and argument checks succeed and the
instantiation will proceed, the constructor's declaring class
is initialized if it has not already been initialized.

If the constructor completes normally, returns the newly
created and initialized instance.

##### Parameters

| initargs | array of objects to be passed as arguments to the constructor call; values of primitive types are wrapped in a wrapper object of the appropriate type (e.g. a `float` in a `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html`) |
|---|---|

##### Returns

- a new object created by calling the constructor this object represents

##### Throws

| [IllegalAccessException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/IllegalAccessException.html) | if this `Constructor` object is enforcing Java language access control and the underlying constructor is inaccessible. |
| [IllegalArgumentException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/IllegalArgumentException.html) | if the number of actual and formal parameters differ; if an unwrapping conversion for primitive arguments fails; or if, after possible unwrapping, a parameter value cannot be converted to the corresponding formal parameter type by a method invocation conversion; if this constructor pertains to an enum type. |
| [InstantiationException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/InstantiationException.html) | if the class that declares the underlying constructor represents an abstract class. |
| [InvocationTargetException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/reflect/InvocationTargetException.html) | if the underlying constructor throws an exception. |
| [ExceptionInInitializerError](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ExceptionInInitializerError.html) | if the initialization provoked by this method fails. |
|---|---|

#### public [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**toGenericString**
()

Returns a string describing this `Constructor`,
including type parameters. The string is formatted as the
constructor access modifiers, if any, followed by an
angle-bracketed comma separated list of the constructor's type
parameters, if any, followed by the fully-qualified name of the
declaring class, followed by a parenthesized, comma-separated
list of the constructor's generic formal parameter types.

If this constructor was declared to take a variable number of
arguments, instead of denoting the last parameter as
"*Type*\[\]", it is denoted as
"*Type*...".

A space is used to separate access modifiers from one another
and from the type parameters or return type. If there are no
type parameters, the type parameter list is elided; if the type
parameter list is present, a space separates the list from the
class name. If the constructor is declared to throw
exceptions, the parameter list is followed by a space, followed
by the word "`throws`" followed by a
comma-separated list of the thrown exception types.

The only possible modifiers for constructors are the access
modifiers `public`, `protected` or
`private`. Only one of these may appear, or none if the
constructor has default (package) access.

##### Returns

- a string describing this `Constructor`, include type parameters

#### public [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**toString**
()

Returns a string describing this `Constructor`. The string is
formatted as the constructor access modifiers, if any,
followed by the fully-qualified name of the declaring class,
followed by a parenthesized, comma-separated list of the
constructor's formal parameter types. For example:

```
    public java.util.Hashtable(int,float)
 
```

The only possible modifiers for constructors are the access
modifiers `public`, `protected` or
`private`. Only one of these may appear, or none if the
constructor has default (package) access.

##### Returns

- a string describing this `Constructor`
