Java in a Nutshell, 5th Edition

Name

Long

Synopsis

This class provides an immutable object wrapper around the long primitive data type. This class also contains useful minimum and maximum constants and useful conversion methods. parseLong( ) and valueOf( ) convert a string to a long or to a Long, respectively. Each can take a radix argument to specify the base the value is represented in. toString( ) converts in the other direction and may also take a radix argument. toBinaryString( ), toOctalString( ), and toHexString( ) convert a long to a string using base 2, base 8, and base 16. These methods treat the long as an unsigned value. Other routines return the value of a Long as various primitive types, and, finally, the getLong( ) methods return the long value of a named property or the value of the specified default.

Java 5.0 adds a number of static methods that operate on the bits of a long value. Except for their argument type and return type, they are the same as the Integer methods of the same name.
