Question

ChatBot Class Modification:

Modify the reply() method of the ChatBot class to recognize additional words and phrases. 

Part 1: Everyone must complete this section.

When the userInput parameter value is:     The reply method should return:
how do I quit                           enter quit
how do I exit                           enter quit
how do I stop                           enter quit
how do I ____                           do you really want to do that
how are you                             I'm fine
how ______                              I don't know

Add two additional words or phrases to recognize and respond to.

ChatBot Client Modification:

Modify the ChatBot client application to loop until the end-user enters "quit".

Here is my client/application class

/**

import java.util.Scanner;
public class ChatbotClient
{
   public static void main(String[] args)
    {
       Scanner input = new Scanner(System.in);

        Chatbot t = new Chatbot();
       System.out.print("What is your name? ");
       String name = input.nextLine();

         System.out.println(t.introbot());

       System.out.print(name + "> ");
       String reply = input.nextLine();

         System.out.println(t.getName() + "> " + t.getreply(reply));
         //while (reply < quit)
         /*{
            quit++
             i = i + 1

         }*/






    }
}

I don’t know what I am doing wrong with this part right here

Modify the ChatBot client application to loop until the end-user enters “quit”.

I am trying to create a while loop which will continue until user says quit.

Answer 1

I think following code should work for your requirements:

import java.util.Scanner;
public class ChatbotClient
{
   public static void main(String[] args)
    {
       Scanner input = new Scanner(System.in);

       Chatbot t = new Chatbot();
       System.out.print("What is your name? ");
       String name = input.nextLine();

       System.out.println(t.introbot());

       System.out.print(name + "> ");
       String reply = input.nextLine();

      while (!reply.equalsIgnoreCase("quit")){
        System.out.println(t.getName() + "> " + t.getreply(reply));
        System.out.print(name + "> ");
        reply = input.nextLine();
      }
     }
}
