题解 | #输入整型数组和排序标识，升序或降序排序#

import java.util.Arrays;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int number = in.nextInt();
        int[] ins = new int[number];
        for(int i=0;i<number;i++){
            ins[i] = in.nextInt();
        }
        int sort = in.nextInt();
        Arrays.sort(ins);
        if(sort==0){
            // asc
            for(int i=0;i<ins.length;i++){
                System.out.print(ins[i]+" ");
            }
        } else {
            // desc
            for(int i=ins.length-1;i>=0;i--){
                System.out.print(ins[i]+" ");
            }
        }
    }
}

知识点：

排序 Arrays.sort(ins);
