Question

Really not sure what I'm doing wrong here...

public class Main {

    public static void main(String[] args) {
    // write your code here
        Scanner in = new Scanner(System.in);
        // TODO:csd - Instantiate a new Prompter object and prompt for the story template
        Prompter prompt = new Prompter();
        System.out.printf("Enter new story:%n");
        String newStory = in.nextLine();
        Template newTemplate = new Template(newStory);

#  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

Hi, Great Job with the code. I see that it works.

You see the problem here is that Craig Dennis

Assumes that you are using BufferedReader and NOT Scanner like used. It is totally find that you use it. It is great. But unfortunately, because initially project files were with Buffered Reader, you have to use it, and not Scanner
Please remove prompting story part to Prompter. It is necessary for you to understand that you created Prompter class to make all user prompts there. Seems logical, right :)

So let me give you how the Main class should look like, and you can try to fill out the missing method I didn't write in Prompter, OK:)?

So, here is how Main.main should look like:

    public static void main(String[] args) {
        // create new Prompter object
        Prompter prompt = new Prompter();

        // prompt for new story: That is the missing class that 
       // you have to implement in Prompter
        String newStory = prompt.promptForStory();

        // create new Template from story
        Template newTemplate = new Template(newStory);

        // run prompter with template
        prompt.run(newTemplate);
    }

So go ahead and implement promptForStory() method using mReader and NOT Scanner. I'm sure you'll made. Post back here if you'll have more errors.
