analysis

1. Enter data with the keyboard as required, n, k, n as the length of the array, and k as the number of returned digits

2. After completing the input as required, call the method in the array, sort, and then splice

Code

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

public class Main4 {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		while (sc.hasNext()) {
			int n = sc.nextInt();
			int k = sc.nextInt();
			int[] arr = new int[n];
			for (int i = 0; i < arr.length; i++) {
				arr[i] = sc.nextInt();
			}
			Arrays.sort(arr);
			StringBuilder ss = new StringBuilder();
			for (int i = 0; i < k; i++) {
				ss.append(arr[i]).append(" ");
			}
			System.out.println(ss.toString().trim());
		}
	}
