Question

我有一个家庭作业。。。代码如下。。。有几个问题要问。。。提前谢谢。Java初学者。。。如果这看起来很笨拙，请不要笑

       {
           public static void main(String[] args)
           {
           Scanner input = new Scanner(System.in);

           System.out.print(
           "Mind answering some questions for me?\n" +
           "Type quit when you're ready to leave.\n");

        if (ans3 == 0)

        String userinput = input.nextLine();
        if (userinput.equalsIgnoreCase("quit"))
            break;      
      }
   }
 }

1. 有没有办法对我问的每个问题使用我的IF语句，而不必为每个问题更改字符串名称？
2. 有没有办法创建一个方法（？）对于那些如果语句，所以我不必为我问的每一个问题写出来？
3. 如果用户在10秒内没有输入答案，我想有一个定时器提示他们回答，我该怎么做？

Answer 1

我建议使用列表来存储响应。这将减少对if语句的需要，还可以避免在四个不同的位置添加新的响应。

List<String> responseList = new ArrayList<String>();
responseList.add("That's awesome!");
responseList.add("LOL!");
responseList.add(.....);

System.out.println(responseList.get(ans));

Answer 2

我不确定这是否回答1，但它应该回答2：

private String getAnswer() {
   int ans = (int)(Math.random() * 5);
   switch(ans) {
   case 0:
      return "That's awesome!";
   case 1:
      return "Awww, how unfortunate!";
   [... and so on ...]
   }
   return null
} 

而不是在你需要这样一个答案的地方调用它：System.out.println（get答案（））；

Answer 3

您可以拥有一个字符串数组，并根据输入ans打印它们：

    String str[] = {"That's awesome!", "Awww, how unfortunate!",
     "You're amazing at this!", "LOL!", "WTF!! That's horrible!"};

      /* code */

  while(true)
       {
        System.out.print("Does your name start with the letter H? ");
        input.nextLine();
        int ans = (int)(Math.random() * str.length);
        System.out.println(str[ans]);

      /* code */
   }
