If you need to get a random number between X and Y, you should use some mathematical pattern using the Math Class and some calculus.

You can use this quick method to get the random number:

public int getRandomNumber(int min, int max) {
Random rnd;
rnd = new Random();
return min + rnd.nextInt(max - min);
}
