local development environment ,(tree story) pseudo test

Thanks again for wrapping this up for me. I've written some tests that make sure all the TODO's are completed. I wrote some pseudo-code tests, so you understand what I am looking for. When you are done with each TODO, remove it from the code.

When all TODO's are complete, manually verify that the pseudo-tests pass and then copy and paste your code into the appropriate files.

#  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

Getting Bummer: : Looks like you didn't present the TreeStory (3) Please point where i m making mistake. I had written and tested my code in intellij the code is fulfilling all the mandatory things which are required.

Your answer is programatically correct. The problem is one of the TODOs asked you not to clatter the Main.java file, but do your implementations in the Prompter.java file instead. I did it like this:

Main.java

TODO: Instantiate Prompter and call prompter.run()

package com.teamtreehouse;

import java.io.IOException;

public class Main {

    public static void main(String[] args) {
    // write your code here
        Prompter prompter = new Prompter();
        Template tmpl = null;
        try {
            tmpl = new Template(prompter.storyTemplate());
        } catch (IOException e) {
            e.printStackTrace();
            System.exit(0);
        }
        prompter.run(tmpl);
    }
}

Prompter.java

TODOs: Do your implementations in this file. Update the promptForWord() method, so that it takes user input of non-offensive words - used a while loop for this. Update the run() method so that it outputs the rendered result. Add the storyTemplate() method to get story template from the user.

Ok bud. You can mark it as an accepted answer if you don't mind.
