There is a way to have global-like variables in Java and I also use
that to set a random number generator. 

public final class Utils {
        static Random rand = new Random();
        }

Thereafter, you can just say Utils.rand.nextInt() to draw random
integers from the same random generator from all your classes.

You can set the seed as well by setting Utils.rand = new Random(seed)
from anywhere. 

Hope that helps.
