Random generator - urgent

Hi,

In matlab, there is this random generator  that is called rand "that returns a pseudorandom, scalar value drawn from a uniform distribution on the unit interval."

Lets say I need to find the equilavent in java, is nextFloat, nextDouble or the Random generator itself.

Math.random()

Pls help.thanks

java.util.Random should be OK

Math.random constructs an instance of Random to use for servicing getDouble calls. So Math.random and Random.getDouble are equivalent. If this is insufficient for your needs, you might have a look at the random package of Colt: http://dsd.lbl.gov/~hoschek/colt/

import java.util.Random;

public class Dummy {
public static void main(String[] args)
{
double rangeMin = 5;
double rangeMax = 10;
Random r = new Random(System.currentTimeMillis());
System.out.println("INT:"    + ((int)rangeMin + r.nextInt((int)rangeMax-(int)rangeMin)));
System.out.println("FLOAT:"  + (rangeMin + r.nextFloat()*(rangeMax-rangeMin)));
System.out.println("DOUBLE:" + (rangeMin + r.nextDouble()*(rangeMax-rangeMin)));

}
