Mersenne Twister 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 MersenneTwisterRNG class.

package com.bethecoder.tutorials.uncommons;

import java.util.Arrays;

import org.uncommons.maths.random.MersenneTwisterRNG;

public class MersenneTwisterRNGTest {

  /**
   @param args
   */
  public static void main(String[] args) {

    MersenneTwisterRNG rand = new MersenneTwisterRNG();
    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());
    
  }

}
   

It gives the following output,
[-52, 102, 70, -99, -103, 83, -125, -123, -30, -116, 52, -113, 67, -77, 116, -75]
