How to Prompt for a New Story

The challenge is asking me to prompt for a new story. I thought I had done that. How do I clear the old story so that the new one is the one I am prompting for. I feel like I am only missing a line or two of code.

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

import java.util.Arrays;
import java.util.List;

public class Main {

    public static void main(String[] args) {        
        Prompter storyPrompter = new Prompter();
        String story = "Thanks __name__ for helping me out.  You are really a __adjective__ __noun__ and I owe you a __noun__.";
        Template tmpl = new Template(story);
        storyPrompter.run(tmpl);
        /*List<String> fakeResults = Arrays.asList(
                "friend",
                "talented",
                "java programmer",
                "high five");*/
    }
}

#  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

you have to create a new method promptForTemplate, add the required fields to change the old phrases. now use the method in place of template
