Program to generate floating point random number.

import java.util.*;

public class RandomDemo2 {
   public static void main( String...args )
   {
// create random object
Random randomno = new Random();

//Float value
System.out.println("Float value between 0.0 and 1.0: "+randomno.nextFloat());

//Double value
System.out.println("Double value between 0.0 and 1.0: "+randomno.nextDouble());

// check next Gaussian value
System.out.println("Next Gaussian value: " + randomno.nextGaussian());
   }    
}
