11 maj 2024 · Let’s use the Math.random method to generate a random number in a given range [min, max): public int getRandomNumber(int min, int max) { return (int) ((Math.random() * (max - min)) + min); } Why does that work?
With Java 8 they introduced the method ints(int randomNumberOrigin, int randomNumberBound) in the Random class. For example if you want to generate five random integers (or a single one) in the range [0, 10], just do: Random r = new Random(); int[] fiveRandomNumbers = r.ints(5, 0, 11).toArray();
