Minimum and maximum random number?

[Jon Camilleri]

I would like to generate a function (unless one is already available), that computes the minimum and maximum values that can be generated by a random number generating formula:

/**
 *  This program generates 5 random numbers and lists them.
 */
import java.math.*;
import java.util.*;
import java.lang.Math.*;

/**

 */
public class Test {

	public static void main(String[] args) {
		Random rn = new Random();
		
		double number = rn.nextDouble();
		
		for (int i =0; i < 5; i++)
		{
			[color=orange]number  = rn.nextDouble() * 1 / Math.pow(number, 2) * 500;[/color]
			System.out.print("Random number: ");
			System.out.println(number);
		}
	}

}

The easiest way is often to read the documentation. Random.nextDouble() returns a value between 0 and 1. Or did you mean something else?

If you just had a "black box" random number function, there'd be no way of getting a definitive answer. All you could do is call it lots of times and get an indication of what the distribution might be.
