Unsigned Integer Arithmetic API now in JDK 8 (Joseph D. Darcy's Oracle Weblog)
At long last, after due discussion and review , I've just pushed initial API support for unsigned integer arithmetic into JDK 8! The support is implemented via static methods, primarily on java.lang.Integer and java.lang.Long , that: Compare values as unsigned Colloquially, "unsigned integer" means a 32-bit int long value where all the bits are interpreted as contributing to the magnitude. In the unsigned realm, the values of an integer type of a given bit-width range from 0 to 2width-1 rather than from -(2width-1) to 2width-1-1. A feature of the two's complement encoding of Java integers is that the bitwise results for add, subtract, and multiply are the same if both inputs are interpreted as signed values or both inputs are interpretted as unsigned values. (Other encodings like one's complement and signed magnitude don't have this properly.) Therefore, of the basic arithmetic operations, only a separate divide method needs to be provided to operate on values interpreted as unsigned.Read full article from Unsigned Integer Arithmetic API now in JDK 8 (Joseph D.
