All Implemented Interfaces:

java.lang.Cloneable

public class RandomJava

extends RandomElement

RandomJava is a class wrapper for the Math.random() generator that comes with Java. I know nothing about the quality of Math.random(), but I will warn the reader that system-supplied RNGs have a bad reputation; RandomJava is NOT reccomended for general use, it has only been included as a straightforward example of how to build a RandomElement wrapper for an existing RNG. The RANMAR, RANECU and RANLUX generators included in this package all appear to be faster than Math.random(); all three are well-studied, portable and proven in use.

Source code is available.
