Error Messages

Hello,

I keep getting error messages when I try to "check work." The code seems to be working well on intelliJ, so I'm quite puzzled at the moment.

Any help will be appreciated!

com/teamtreehouse/Main.java 
package com.teamtreehouse;

import java.io.IOException;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class Main {

    public static void main(String[] args) {
        Prompter prompter = new Prompter();
        String story = "";
        try {
            story = prompter.newStory();
        } catch (IOException e) {
            e.printStackTrace();
        }
        Template tmpl = new Template(story);
        prompter.run(tmpl);

    }

#  This is essentially what I am testing 
1.  The user is prompted for a new string template (the one with the double underscores in it).

  a. The prompter class has a new method that prompts for the story template, and that method is called.

2.  The user is then prompted for each word that has been double underscored.

   a. The answer is checked to see if it is contained in the censored words.
      User is continually prompted until they enter a valid word

3.  The user is presented with the completed story

Richard,

Your issue is with the promptForWord method

      public String promptForWord(String phrase) throws IOException {

          //Use System.out.printf("Please enter a %s", phrase);
          System.out.println("Please enter a word: ");  

         //phrase is name, adjective, verb, noun. You do not want to overwrite it.
         //Use: String response = mReader.readLine(); instead.  
         phrase = mReader.readLine(); 

        //replace phrase with response throughout the rest
         while (mCensoredWords.contains(phrase)) {
            System.out.println("That word is not allowed! Please enter another one.");
            phrase = mReader.readLine();
        }
        return phrase;
    }

I made the changes and tested it in the challenge. It works fine once the changes are done. Let me know if you have any issues though.

Regards,

Chris
