題目是簡單的, 但是一直有一個點沒有通過, 最後我發現我沒有考慮如果直接輸入"." , 也就是LinkedList容器內沒有元素時的情況

這道題目給我的啟示是, 寫簡單的題目, 要萬分小心, 把該考慮的情況都要考慮清楚了, 這才能把分數都拿到手.

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.LinkedList;
import java.util.Queue;

public class Main {

    public static void main(String[] args) throws
 
 Exception{
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        Queue<String> linkedlist = new LinkedList<String>();
        while(true) {
            String str = br.readLine();
            if(str.equals(".")) {
                break;
            } 
 
else if(str.equals("")) {
                break;
            } else if (str.length() > 10) {
                break;
            } else {
                linkedlist.add(str);
            }
        }
        if (linkedlist.isEmpty()) {
            System.out.print("Momo... No one is for you ...");
            
 
return;
        }
        if (linkedlist.size() == 1) {
            System.out.print("Momo... No one is for you ...");
            return;
        } else if (linkedlist.size() >= 2 && linkedlist.size() < 14) {
            linkedlist.remove();
            String name = linkedlist.poll();
            System.out.print(name + " is the only one for you...");
            return;
        } else {
            linkedlist.remove();
            String second_name = linkedlist.poll();
            for(int i=0; i<11; i++) {
                linkedlist.remove();
            }
            String fifteen_name = linkedlist.poll();
            System.out.print(second_name+" and "+fifteen_name+" are inviting you to dinner...");
        }

    }
