直接利用java的数组Arrays.sort方法

import java.util.*;
public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        Collection<String> list = new ArrayList<String>();
        while(in.hasNextLine()){
            int n = Integer.parseInt(in.nextLine());
            for(int i=0;i<n;i++){
                String line = in.nextLine();
                list.add(line);
            }
        }
        Object[] array = list.toArray();
        Arrays.sort(array);
        for(Object str:array){
            System.out.println(str.toString());
        }
    }
}
