Exercise: remove TODO

Bummer! Whoops looks like you forgot to remove the TODO's after you completed them. This helps everyone know it is done.

What am I supposed to do?

// After you've completed the TODOs locally paste Main.java here
package com.teamtreehouse;

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

public class Main {

    public static void main(String[] args) {
    // write your code here
        Prompter prompter = new Prompter();
// After you've completed the TODOs locally paste Prompter.java here

            Matcher matcher = pattern.matcher(story);
                String found = matcher.group();

        return words;

     * Prompts the user for the answer to the fill in the blank.  Value is guaranteed to be not in the censored words list.

    public String promptForWord(String phrase) throws IOException, ClassCastException {

        } while (getmCensoredWords().contains(readString));
        return readString;

    public String mTemplate() throws IOException {
        System.out.println("Please entry your story template");
        return  mReader.readLine().trim();

#  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

Delete the comments with TODO that were left there originally. That should take care of this problem.
