What are the odds this will work?

What are the chances that the number will be guessed in this code:

package numberguesser;

import java.util.Random;

public class Main {

    public static void main(String[] args) {
        int guess, number;
        Random rand = new Random();
        number = rand.nextInt(1000000000) + 1;
        guess = rand.nextInt(1000000000) + 1;
        while (guess != number) {
            System.out.println("Trying " + guess);
            guess = rand.nextInt(1000000000) + 1;
        }
        System.out.println("The number was guessed.  It was " + number);
    }

}

Because a uniform probability distribution carries no memory chances are
1:1000000000 that a number equals the wanted one.

I don't know the characteristics of the pseudo random number generator that
is used by Java so the numbers might differ.

Yeah I found out the chances were pretty low after running it 10 times with no success. I left each one running for a while to :-)

Try to lower the number of zeros from that huge number and give it another try.
Playing with numbers can be fun to the completely deranged ;-)
