How do I get a random number with a negative number in range? [duplicate]

Answer 1

To get a random number between a set range with min and max:

int number = random.nextInt(max - min) + min;

It also works with negative numbers.

So:

random.nextInt(30 + 10) - 10;
// max = 30; min = -10;

Will yield a random int between -10 and 30 (exclusive).

It also works with doubles.
