public class App {
    public static void main(String[ ] args) {
        List<Integer> list = new ArrayList<>(List.of(5, 3, 2, 1, 4));

        Collections.sort(list);
        System.out.println(list); // => [1, 2, 3, 4, 5]

        list.sort(Comparator.reverseOrder());
        System.out.println(list); // => [5, 4, 3, 2, 1]

        list = list.stream()
                .sorted()
                .collect(Collectors.toList());
        System.out.println(list); // => [1, 2, 3, 4, 5]
