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; }
