Answer 1

 public static void main(String[] args) {
        Scanner input =new Scanner(System.in);
        System.out.println("请输入一个整数（1，200）:");
        int n=input.nextInt();
        List<Integer> list=new ArrayList<>();
        for (int i = 0; i <n ; i++) {
            Random r=new Random();
            int a=r.nextInt(10000);
            list.add(a);
        }
        System.out.println("元数据是：");
        System.out.println(list);
        System.out.println("从小到大排序：");
        Collections.sort(list);
        System.out.println(list);
    }
