Java- dice rolling program

Question

The goal is to create a program that beat simulated the value produced as a result of rolling 2 number cubes (their sum, 1-6 inclusive, equal probability that it is any of the numbers). Which method below is the best and why?
(int) (Math.random() * 13);
Or
2+ (int) (Math.random()*6) + (int)(Math.random() * 6)
Thanks!

Answer 1

Hello
I would use Random rnd = new Random();
rnd.nextInt(6) + rnd.nextInt(6) + 2;

In your case the second option looks more efficient than the 1st one.
