# Long

public final class **Long** extends [Number](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Number.html)  
implements [Comparable](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Comparable.html)\<[Long](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html)\> The `Long` class wraps a value of the primitive type `long` in an object. An object of type `Long` contains a
single field whose type is `long`.

In addition, this class provides several methods for converting
a `long` to a `String` and a `String` to a `long`, as well as other constants and methods useful when dealing
with a `long`.

Implementation note: The implementations of the "bit twiddling"
methods (such as `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#highestOneBit(long)` and
`https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#numberOfTrailingZeros(long)`) are
based on material from Henry S. Warren, Jr.'s *Hacker's Delight*, (Addison Wesley, 2002).

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

Compares this object to the specified object. The result is
`true` if and only if the argument is not
`null` and is a `Long` object that
contains the same `long` value as this object.

##### Parameters

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

##### Returns

- `true` if the objects are the same; `false` otherwise.

#### public float
**floatValue**
()

Returns the value of this `Long` as a `float` after
a widening primitive conversion.

**getLong**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) nm, [Long](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html) val)

Returns the `long` value of the system property with
the specified name. The first argument is treated as the name
of a system property. System properties are accessible through
the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/System.html#getProperty(java.lang.String)`
method. The string value of this property is then interpreted
as a `long` value, as per the
`https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#decode(java.lang.String)` method, and a `Long` object
representing this value is returned; in summary:

- If the property value begins with the two ASCII characters `0x` or the ASCII character `#`, not followed by a minus sign, then the rest of it is parsed as a hexadecimal integer exactly as for the method `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#valueOf(java.lang.String,%20int)` with radix 16.
- If the property value begins with the ASCII character `0` followed by another character, it is parsed as an octal integer exactly as by the method `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#valueOf(java.lang.String,%20int)` with radix 8.
- Otherwise the property value is parsed as a decimal integer exactly as by the method `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#valueOf(java.lang.String,%20int)` with radix 10.

Note that, in every case, neither `L`
(`'\u004C'`) nor `l`
(`'\u006C'`) is permitted to appear at the end
of the property value as a type indicator, as would be
permitted in Java programming language source code.

The second argument is the default value. The default value is
returned if there is no property of the specified name, if the
property does not have the correct numeric format, or if the
specified name is empty or `null`.

##### Parameters

| nm | property name. |
| val | default value. |
|---|---|

##### Returns

- the `Long` value of the property.

##### Throws

| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | for the same reasons as `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/System.html#getProperty(java.lang.String)` |

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

Determines the `long` value of the system property
with the specified name.

The first argument is treated as the name of a system
property. System properties are accessible through the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/System.html#getProperty(java.lang.String)` method. The
string value of this property is then interpreted as a `long` value using the grammar supported by `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#decode(java.lang.String)`
and a `Long` object representing this value is returned.

If there is no property with the specified name, if the
specified name is empty or `null`, or if the property
does not have the correct numeric format, then `null` is
returned.

In other words, this method returns a `Long` object
equal to the value of:

> `getLong(nm, null)`

<br />

##### Parameters

| nm | property name. |
|---|---|

##### Returns

- the `Long` value of the property.

##### Throws

| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | for the same reasons as `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/System.html#getProperty(java.lang.String)` |

#### public static [Long](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html)
**getLong**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) nm, long val)

Determines the `long` value of the system property
with the specified name.

The first argument is treated as the name of a system
property. System properties are accessible through the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/System.html#getProperty(java.lang.String)` method. The
string value of this property is then interpreted as a `long` value using the grammar supported by `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#decode(java.lang.String)`
and a `Long` object representing this value is returned.

The second argument is the default value. A `Long` object
that represents the value of the second argument is returned if there
is no property of the specified name, if the property does not have
the correct numeric format, or if the specified name is empty or null.

In other words, this method returns a `Long` object equal
to the value of:

> `getLong(nm, new Long(val))`
but in practice it may be implemented in a manner such as:
>
> ```
>  Long result = getLong(nm, null);
>  return (result == null) ? new Long(val) : result;
>  
> ```
to avoid the unnecessary allocation of a `Long` object when the default value is not needed.

<br />

##### Parameters

| nm | property name. |
| val | default value. |
|---|---|

##### Returns

- the `Long` value of the property.

##### Throws

| [SecurityException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/SecurityException.html) | for the same reasons as `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/System.html#getProperty(java.lang.String)` |

Parses the string argument as a signed decimal `long`.
The characters in the string must all be decimal digits, except
that the first character may be an ASCII minus sign `'-'`
(`\u002D'`) to indicate a negative value or an
ASCII plus sign `'+'` (`'\u002B'`) to
indicate a positive value. The resulting `long` value is
returned, exactly as if the argument and the radix `10`
were given as arguments to the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#parseLong(java.lang.String,%20int)` method.

Note that neither the character `L`
(`'\u004C'`) nor `l`
(`'\u006C'`) is permitted to appear at the end
of the string as a type indicator, as would be permitted in
Java programming language source code.

##### Parameters

| s | a `String` containing the `long` representation to be parsed |
|---|---|

##### Returns

- the `long` represented by the argument in decimal.

##### Throws

| [NumberFormatException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NumberFormatException.html) | if the string does not contain a parsable `long`. |

**parseLong**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) s, int radix)

Parses the string argument as a signed `long` in the
radix specified by the second argument. The characters in the
string must all be digits of the specified radix (as determined
by whether `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Character.html#digit(char,%20int)` returns
a nonnegative value), except that the first character may be an
ASCII minus sign `'-'` (`'\u002D'`) to
indicate a negative value or an ASCII plus sign `'+'`
(`'\u002B'`) to indicate a positive value. The
resulting `long` value is returned.

Note that neither the character `L`
(`'\u004C'`) nor `l`
(`'\u006C'`) is permitted to appear at the end
of the string as a type indicator, as would be permitted in
Java programming language source code - except that either
`L` or `l` may appear as a digit for a
radix greater than or equal to 22.

An exception of type `NumberFormatException` is
thrown if any of the following situations occurs:

- The first argument is `null` or is a string of length zero.
- The `radix` is either smaller than `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Character.html#MIN_RADIX` or larger than `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Character.html#MAX_RADIX`.
- Any character of the string is not a digit of the specified radix, except that the first character may be a minus sign `'-'` (`'\u002d'`) or plus sign `'+'` (`'\u002B'`) provided that the string is longer than length 1.
- The value represented by the string is not a value of type `long`.

([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) s, int radix)

Parses the string argument as an unsigned `long` in the
radix specified by the second argument. An unsigned integer
maps the values usually associated with negative numbers to
positive numbers larger than `MAX_VALUE`.

The characters in the string must all be digits of the
specified radix (as determined by whether `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Character.html#digit(char,%20int)` returns a nonnegative
value), except that the first character may be an ASCII plus
sign `'+'` (`'\u002B'`). The resulting
integer value is returned.

**rotateLeft**
(long i, int distance)

Returns the value obtained by rotating the two's complement binary
representation of the specified `long` value left by the
specified number of bits. (Bits shifted out of the left hand, or
high-order, side reenter on the right, or low-order.)

Note that left rotation with a negative distance is equivalent to
right rotation: `rotateLeft(val, -distance) == rotateRight(val,
distance)`. Note also that rotation by any multiple of 64 is a
no-op, so all but the last six bits of the rotation distance can be
ignored, even if the distance is negative: `rotateLeft(val,
distance) == rotateLeft(val, distance & 0x3F)`.

##### Parameters

| i | the value whose bits are to be rotated left |
| distance | the number of bit positions to rotate left |
|---|---|

##### Returns

#### public static long
**rotateRight**
(long i, int distance)

Returns the value obtained by rotating the two's complement binary
representation of the specified `long` value right by the
specified number of bits. (Bits shifted out of the right hand, or
low-order, side reenter on the left, or high-order.)

Note that right rotation with a negative distance is equivalent to
left rotation: `rotateRight(val, -distance) == rotateLeft(val,
distance)`. Note also that rotation by any multiple of 64 is a
no-op, so all but the last six bits of the rotation distance can be
ignored, even if the distance is negative: `rotateRight(val,
distance) == rotateRight(val, distance & 0x3F)`.

##### Parameters

| i | the value whose bits are to be rotated right |

**toBinaryString**
(long i)

Returns a string representation of the `long`
argument as an unsigned integer in base 2.

The unsigned `long` value is the argument plus
2^64^ if the argument is negative; otherwise, it is
equal to the argument. This value is converted to a string of
ASCII digits in binary (base 2) with no extra leading
`0`s.

The value of the argument can be recovered from the returned
string `s` by calling `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#parseUnsignedLong(java.lang.String,%20int)`.

If the unsigned magnitude is zero, it is represented by a
single zero character `'0'` (`'\u0030'`);
otherwise, the first character of the representation of the

**toHexString**
(long i)

Returns a string representation of the `long`
argument as an unsigned integer in base 16.

The unsigned `long` value is the argument plus
2^64^ if the argument is negative; otherwise, it is
equal to the argument. This value is converted to a string of
ASCII digits in hexadecimal (base 16) with no extra
leading `0`s.

The value of the argument can be recovered from the returned
string `s` by calling `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#parseUnsignedLong(java.lang.String,%20int)`.

If the unsigned magnitude is zero, it is represented by a
single zero character `'0'` (`'\u0030'`);
otherwise, the first character of the representation of the
unsigned magnitude will not be the zero character. The
following characters are used as hexadecimal digits:

> `0123456789abcdef`
These are the characters `'\u0030'` through `'\u0039'` and `'\u0061'` through `'\u0066'`. If uppercase letters are desired, the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html#toUpperCase()` method may be called on the result: `Long.toHexString(n).toUpperCase()`

**toOctalString**
(long i)

Returns a string representation of the `long`
argument as an unsigned integer in base 8.

The unsigned `long` value is the argument plus
2^64^ if the argument is negative; otherwise, it is
equal to the argument. This value is converted to a string of
ASCII digits in octal (base 8) with no extra leading
`0`s.

The value of the argument can be recovered from the returned
string `s` by calling `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#parseUnsignedLong(java.lang.String,%20int)`.

If the unsigned magnitude is zero, it is represented by a
single zero character `'0'` (`'\u0030'`);
otherwise, the first character of the representation of the
unsigned magnitude will not be the zero character. The
following characters are used as octal digits:

> `01234567`
These are the characters `'\u0030'` through `'\u0037'`.

<br />

##### Parameters

**toString**
(long i, int radix)

Returns a string representation of the first argument in the
radix specified by the second argument.

If the radix is smaller than `Character.MIN_RADIX`
or larger than `Character.MAX_RADIX`, then the radix
`10` is used instead.

If the first argument is negative, the first element of the
result is the ASCII minus sign `'-'`
(`'\u002d'`). If the first argument is not
negative, no sign character appears in the result.

The remaining characters of the result represent the magnitude
of the first argument. If the magnitude is zero, it is
represented by a single zero character `'0'`
(`'\u0030'`); otherwise, the first character of
the representation of the magnitude will not be the zero
character. The following ASCII characters are used as digits:

> `0123456789abcdefghijklmnopqrstuvwxyz`
These are `'\u0030'` through `'\u0039'` and `'\u0061'` through `'\u007a'`. If `radix` is <var translate="no">N</var>, then the first <var translate="no">N</var> of these characters are used as radix-<var translate="no">N</var> digits in the order shown. Thus, the digits for hexadecimal (radix 16) are `0123456789abcdef`. If uppercase letters are desired, the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html#toUpperCase()` method may be called on the result: `Long.toString(n, 16).toUpperCase()`

- `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Character.html#MIN_RADIX`

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

Returns a `String` object representing this
`Long`'s value. The value is converted to signed
decimal representation and returned as a string, exactly as if
the `long` value were given as an argument to the
`https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#toString(long)` method.

##### Returns

- a string representation of the value of this object in base 10.

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

Returns a `String` object representing the specified
`long`. The argument is converted to signed decimal
representation and returned as a string, exactly as if the
argument and the radix 10 were given as arguments to the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#toString(long,%20int)` method.

##### Parameters

| i | a `long` to be converted. |
|---|---|

##### Returns

- a string representation of the argument in base 10.

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

Returns a string representation of the argument as an unsigned
decimal value.

The argument is converted to unsigned decimal representation
and returned as a string exactly as if the argument and radix
10 were given as arguments to the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#toUnsignedString(long,%20int)` method.

##### Parameters

| i | an integer to be converted to an unsigned string. |
|---|---|

##### Returns

- an unsigned string representation of the argument.

##### See Also

- `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#toUnsignedString(long,%20int)`

#### public static [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**toUnsignedString**
(long i, int radix)

Returns a string representation of the first argument as an
unsigned integer value in the radix specified by the second
argument.

If the radix is smaller than `Character.MIN_RADIX`
or larger than `Character.MAX_RADIX`, then the radix
`10` is used instead.

Note that since the first argument is treated as an unsigned
value, no leading sign character is printed.

If the magnitude is zero, it is represented by a single zero
character `'0'` (`'\u0030'`); otherwise,
the first character of the representation of the magnitude will
not be the zero character.

The behavior of radixes and the characters used as digits
are the same as `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#toString(long,%20int)`.

##### Parameters

| i | an integer to be converted to an unsigned string. |
| radix | the radix to use in the string representation. |
|---|---|

##### Returns

- an unsigned string representation of the argument in the specified radix.

##### See Also

- `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#toString(long,%20int)`

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

Returns a `Long` object holding the value
of the specified `String`. The argument is
interpreted as representing a signed decimal `long`,
exactly as if the argument were given to the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#parseLong(java.lang.String)` method. The result is a
`Long` object that represents the integer value
specified by the string.

In other words, this method returns a `Long` object
equal to the value of:

> `new Long(Long.parseLong(s))`

<br />

##### Parameters

| s | the string to be parsed. |
|---|---|

##### Returns

- a `Long` object holding the value represented by the string argument.

##### Throws

| [NumberFormatException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NumberFormatException.html) | If the string cannot be parsed as a `long`. |
|---|---|

**valueOf**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) s, int radix)

Returns a `Long` object holding the value
extracted from the specified `String` when parsed
with the radix given by the second argument. The first
argument is interpreted as representing a signed
`long` in the radix specified by the second
argument, exactly as if the arguments were given to the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#parseLong(java.lang.String,%20int)` method. The result is a
`Long` object that represents the `long`
value specified by the string.

In other words, this method returns a `Long` object equal
to the value of:

> `new Long(Long.parseLong(s, radix))`

<br />

##### Parameters

| s | the string to be parsed |
| radix | the radix to be used in interpreting `s` |
|---|---|

##### Returns

- a `Long` object holding the value represented by the string argument in the specified radix.

##### Throws

| [NumberFormatException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NumberFormatException.html) | If the `String` does not contain a parsable `long`. |
|---|---|

#### public static [Long](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html)
**valueOf**
(long l)

Returns a `Long` instance representing the specified
`long` value.
If a new `Long` instance is not required, this method
should generally be used in preference to the constructor
`https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Long.html#Long(long)`, as this method is likely to yield
significantly better space and time performance by caching
frequently requested values.

Note that unlike the {@linkplain Integer#valueOf(int)
corresponding method} in the `Integer` class, this method
is *not* required to cache values within a particular
range.

##### Parameters

| l | a long value. |
|---|---|

##### Returns

- a `Long` instance representing `l`.
