Random

Random random = new Random();

int number = random.nextInt(4);

System.out.println(number);

Denna kod ger ett värde ( som sätts i variabeln "number") som är mellan 0-4

This Random().nextInt(int bound) generates a random integer from 0 (inclusive) to bound (exclusive).

1.1 Code snippet.

For getRandomNumberInRange(5, 10), this will generates a random integer between 5 (inclusive) and 10 (inclusive).

private static int getRandomNumberInRange(int min, int max) {

if (min >= max) {

throw new IllegalArgumentException("max must be greater than min");

}

Random r = new Random();

return r.nextInt((max - min) + 1) + min;

}
