THE PACKAGE JAVA.LANG

20.8.3

public Long(long value)

This constructor initializes a newly created

Long

 object so that it represents the

primitive value that is the argument.

20.8.4

public Long(String s) throws NumberFormatException

This constructor initializes a newly created

Long

 object so that it represents the

integer represented by the string in decimal form. The string is converted to a

long

 value in exactly the manner used by the

parseLong

 method ( 20.8.17) for

radix 10.

20.8.5

public String toString()

The

long

 integer value represented by this

Long

 object is converted to signed dec 

imal representation and returned as a string, exactly as if the integer value were

given as an argument to the

toString

 method that takes one argument ( 20.7.12).

Overrides the

toString

 method of

Object

 ( 20.1.2).

20.8.6

public boolean equals(Object obj)

The result is

true

 if and only if the argument is not

null

 and is a

Long

 object that

represents the same

long

 value as this

Long

 object.

Overrides the

equals

 method of

Object

 ( 20.1.3).

20.8.7

public int hashCode()

The result is the exclusive OR of the two halves of the primitive

long

 value repre 

sented by this

Long

 object. That is, the hashcode is the value of the expression:

(int)(this.longValue()^(this.longValue()>>>32))

Overrides the

hashCode

 method of

Object

 ( 20.1.4).

20.8.8

public int intValue()

The

long

 value represented by this

Long

 object is converted ( 5.1.3) to type

int

and the result of the conversion is returned.

Overrides the

intValue

 method of

Number

 ( 20.6.1).
