Question

java while语句键盘输入十个数字求最大值 次大值

Answer 1

 ArrayList<Integer> integers = new ArrayList<>();

        Random random = new Random();
        for (int i = 0; i < 10; i++) {
            int nextInt = random.nextInt(100);
            integers.add(nextInt);
        }

        Collections.sort(integers);

        //取最大值
        Integer max = integers.get(integers.size()-1);
        Integer max2 = integers.get(integers.size()-2);
        System.out.println("max = " + max);
        System.out.println("max2 = " + max2);
