Creates a new random number generator using a single seed. The seed is the initial value of the internal state of the pseudorandom number generator which is maintained by method next(int) . new Random(seed) Parameters:
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();
W takich momentach, z pomocą przychodzi nam klasa Random. Klasa ta, udostępnia nam kilka metod, za pomocą których wygenerujemy sobie dowolnego typu liczby pseudolosowe, z wybranych przez siebie zakresów. Wymienię i opiszę kilka bardziej przydatnych metod.
