输入n个整数，输出其中最小的k个。 本题有多组输入样例，请使用循环读入，比如while(cin>>)等方式处理

import java.util.*;

public class Main {

public static void main(String[] args) {

    Scanner scanner = new Scanner(System.in);
    while (scanner.hasNext()) {

        String nextLine = scanner.nextLine();
        String[] s = nextLine.split(" ");

        String nextLine2 = scanner.nextLine();
        String[] s1 = nextLine2.split(" ");

        List<String> strings = Arrays.asList(s1);
        strings.sort(new Comparator<String>() {
            @Override
            public int compare(String o1, String o2) {
                return Integer.valueOf(o1) - Integer.valueOf(o2);
            }
        });
        for (int i = 0; i < Integer.valueOf(s[1]); i++) {
            System.out.print(s1[i] + " ");
        }
        System.out.println();
    }
}
