_x000D_ _x000D_ 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`.
