输入整型数组和排序标识，对其元素按照升序或降序进行排序

import java.util.Scanner;
import java.util.*;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        while (sc.hasNext()) {
            int n = sc.nextInt();
            Integer[] arr = new Integer[n];
            for (int i = 0; i < n; i++) {
                arr[i] = sc.nextInt();
            }
            int k = sc.nextInt();
            if (k == 0) {
                Arrays.sort(arr);
            }
            if (k == 1) {
                Arrays.sort(arr, Collections.reverseOrder());
            }
            for (int i = 0; i < arr.length; i++) {
                System.out.print(arr[i] + " ");
            }
            System.out.println();
        }
    }
