XOR Shift Random Number Generator
Uncommons Maths is a java library with nice math utilities and random number generators.
This requires the library uncommons-maths-1.2.2.jar to be in classpath.
The following example shows using XORShiftRNG class.
package com.bethecoder.tutorials.uncommons; import java.util.Arrays; import org.uncommons.maths.random.XORShiftRNG; public class XORShiftRNGTest { /** * @param args */ public static void main ( String [] args ) { XORShiftRNG rand = new XORShiftRNG () ; System.out.println ( Arrays.toString ( rand.getSeed ())) ; System.out.println ( rand.nextInt ()) ; System.out.println ( rand.nextDouble ()) ; System.out.println ( rand.nextGaussian ()) ; System.out.println ( rand.nextBoolean ()) ; } }
