Question

我正在开发一个Chat Bot项目，而且我差不多完成了，除了每当我输入一个输入时，它会根据输入X的长度返回多个输出。

以下是源代码：

import java.util.*;
public class ChatBot
{
public static String getResponse(String value)
{
    Scanner input = new Scanner (System.in);
    String X = longestWord(value);
    if (value.contains("you"))
    {
        return "I'm not important. Let's talk about you instead.";
    }
    else if (X.length() <= 3)
    {
        return "Maybe we should move on. Is there anything else you would like to talk about?";
    }
    else if (X.length() == 4)
    {
        return "Tell me more about " + X;
    }

    else if (X.length() == 5)
    {
        return "Why do you think " + X + " is important?";
    }

    return "Now we are getting somewhere. How does " + X + " affect you the most?";
}

private static String longestWord(String value){
    Scanner input = new Scanner (value);
    String longest = new String();
    "".equals(longest);

    while (input.hasNext())
    {
        String temp = input.next();
        if(temp.length() > longest.length())
        {
            longest = temp;
        }
    }
    return longest;
}

}

这是用于测试聊天机器人：

import java.util.Scanner;


public class Test {
    public static void main (String [ ] args)
    {
    Scanner input = new Scanner (System.in);
    ChatBot e = new ChatBot();
    String prompt = "What would you like to talk about?";
    System.out.println(prompt);
    String userInput;
    userInput = input.next();
    while (!userInput.equals("Goodbye"))
    {
        System.out.println(e.getResponse(userInput));
        userInput = input.next();
    }

}
}

I am also trying to modify the Bot so it counts the number of times it has responded; and also modify it so it randomly returns a random response depending on the length of the input. Any help will be much appreciated. Thank You!

关于计算回复，只需修改主要方法：

import java.util.Scanner;

public class Test {
public static void main (String [ ] args)
{
   int numberOfResponses = 1;
   Scanner input = new Scanner (System.in);
   ChatBot e = new ChatBot();
   String prompt = "What would you like to talk about?";
   System.out.println(prompt);
   String userInput;
   userInput = input.next();
   while (!userInput.equals("Goodbye"))
   {
      System.out.println(e.getResponse(userInput));
      userInput = input.nextLine();
      numberOfResponses++;
   }
   input.close();
   System.out.println(numberOfResponses);
}
}

如果我有时间，我会在几分钟内编辑我的帖子，以检查有关回复双重外观的问题。您也忘了关闭扫描仪。

编辑：实际上是因为扫描仪默认将分隔符设置为空格。因此，如果您输入带有空格的文本，则while循环会针对一个用户输入运行两次。只需使用nextLine（）命令。

为什么这段代码：

 Scanner input = new Scanner (System.in);

在你的getResponse方法中？它根本没用过。仔细看看你的方法，因为他们拿着一些奇怪的代码。

Answer 2

您正在使用Scanner.next方法，该方法仅返回字符串中的下一个单词。因此，如果您输入包含多个单词的字符串，您的机器人将对每个单词进行响应。

您可以使用Scanner.nextLine()来获取整个输入字符串，而不只是1个字。

要计算机器人响应的次数，您可以在机器人类中创建一个字段：

private int responseCount = 0;

然后，如果将yout getResponse方法从静态方法更改为实例方法，则可以从此方法更新此值：

public String getResponse(String value)
{
    String X = longestWord(value);  //Your longestWord should also not be static.
    this.responseCount++;        

    if (value.contains("you"))
    {
        ...
