Java实现对输入的n个数排序

输入n个数，对其进行排序

import java.util.Scanner;
import java.util.Arrays;
public class Main{
    public static void main(String[] args){
        Scanner in =  new Scanner(System.in);
        while (in.hasNext()){
            int n = in.nextInt();
            int [] arr =  new int [n];
            for ( int i= 0 ;i

                arr[i] = in.nextInt();
            }
            Arrays.sort(arr);
            for ( int i= 0 ;i

                System.out.print(arr[i]+ " " );
            System.out.println();
        }
    }
}
