第一个参数控制数组长度，依次使用nextInt进行读取

import java.util.*;
public class Main{
    public static void main(String [] args){
        getArrayNumbers();
    }
    public static void getArrayNumbers(){
        Scanner scan = new Scanner(System.in);
        while(scan.hasNext()){
            int nums = scan.nextInt();
            int len = scan.nextInt();
            int [] arrs = new int[nums];
            for(int i = 0; i < nums; i++){
                arrs [i] = scan.nextInt();
            }
            Arrays.sort(arrs);
            for(int i = 0; i < len; i++){
                System.out.print(arrs[i] + " ");
            }
            System.out.println();
        }
    }
}
