Stream的去重排序

List<Integer> list = new ArrayList<>();
list.add(50);
list.add(25);
list.add(25);
list.add(98);
list.add(32);
List<Integer> collect = list.stream().distinct().sorted().collect(Collectors.toList());
System.out.println("去重正序" + collect);
List<Integer> collect1 = list.stream().distinct().sorted(Comparator.reverseOrder()).collect(Collectors.toList());
System.out.println("去重倒序" + collect1);

打印结果
去重正序[25, 32, 50, 98]
去重倒序[98, 50, 32, 25]
