How do I generate random integers within a specific range in Java?
How do I generate a random int value in a specific range?
I have tried the following, but those do not work:
Attempt 1:
randomNum = minimum + (int)(Math.random() * maximum);
Bug: randomNum can be bigger than maximum.
Attempt 2:
Random rn = new Random();
int n = maximum - minimum + 1;
int i = rn.nextInt() % n;
randomNum = minimum + i;
Bug: randomNum can be smaller than minimum.
