I cannot complete the "Teamwork" challenge.

Hi,

Below are the main and prompter classes:

Main:

package com.teamtreehouse;

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

import java.io.*;

public class Main {

    public static void main(String[] args) {
    // write your code here
        BufferedReader story = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Please enter your story... ");
        String newStory ="";
        try {
            newStory = story.readLine();
        }catch (IOException e){
            System.out.println("Couldn't load censored words");
            e.printStackTrace();
        }
        System.out.printf("Your story is: %s%n", newStory);
        //String story = "Thanks __name__ for helping me out.  You are really a __adjective__ __noun__ and I owe you a __noun__.";
        Template tmpl = new Template(newStory);
        Prompter prompter = new Prompter();
        try {
            List<String> promptedTemplate = prompter.promptForWords(tmpl);
        } catch (IOException e) {
            e.printStackTrace();
        }
        prompter.run(tmpl);


    }
}

Prompter:

package com.teamtreehouse;

import java.io.*;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.*;


public class Prompter {
    private BufferedReader mReader;
    private Set<String> mCensoredWords;

    public Prompter() {
        mReader = new BufferedReader(new InputStreamReader(System.in));
        loadCensoredWords();
    }

    private void loadCensoredWords() {
        mCensoredWords = new HashSet<String>();
        Path file = Paths.get("resources", "censored_words.txt");
        List<String> words = null;
        try {
            words = Files.readAllLines(file);
        } catch (IOException e) {
            System.out.println("Couldn't load censored words");
            e.printStackTrace();
        }
        mCensoredWords.addAll(words);
    }

    public void run(Template tmpl) {
        List<String> results = null;
        try {
            results = promptForWords(tmpl);
        } catch (IOException e) {
            System.out.println("There was a problem prompting for words");
            e.printStackTrace();
            System.exit(0);
        }
        String resultsOfSting = tmpl.render(results);
        System.out.printf("Your TreeStory:%n%n%s", resultsOfSting);
    }

    /**
     * Prompts user for each of the blanks
     *
     * @param tmpl The compiled template
     * @return
     * @throws IOException
     */
    public List<String> promptForWords(Template tmpl) throws IOException {
        List<String> words = new ArrayList<String>();
        for (String phrase : tmpl.getPlaceHolders()) {
            String word = promptForWord(phrase);
            words.add(word);
        }
        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.
     *
     * @param phrase The word that the user should be prompted.  eg: adjective, proper noun, name
     * @return What the user responded
     */
    public String promptForWord(String phrase) throws IOException {
        System.out.printf("Enter the '%s'.%n", phrase);
        String response;
        do{
            System.out.println("Please type an uncensored word.");
            response = mReader.readLine();
        }while (mCensoredWords.contains(response));

        System.out.printf("You typed %s%n", response);
        return response;
    }
}

Moderator edited: Added markdown so the code renders properly in the forums.

When I check my worl I get : " Bummer! Looks like you didn't present the TreeStory (3)" which is point 3. The user is presented with the completed story from the pseudo test. I thought I just need to print ou the story as a result? I am not sure what to do anymore. I am looking forward for your answers.

I am having the same problem :(

Good Morning Alexandra,

On line one of Prompter change your import.java.util.; to import java.util.star; you are missing the star. The same is true on line one of Prompter with your import.java.io.;. Change it to import.java.io.star; You need to include the star or the specific part of the library like you did for the other libraries you imported.

When I posted my answer before the star would not show up. So I wrote the word "star", but I mean the symbol of shift and the 8 key. I am not sure why that is. Maybe someone could elaborate on this as well.

Bear with me. I am learning also but I think your code in public void run(Template tmpl) { needs to be in a new file. Maybe someone else can clarify this.

The method render may be missing in your program.

You may need one more } at the end of your Prompter program.

My answer is probably not complete. Make these corrections and repost. Also, other Treehouse students could add and modify my suggestions.

Thank you,

Mark

Hi Mark! As you can see, she has the java.util.*. I'm curious as to why it's not showing up on your end. That being said, the reason you might not be able to get * to show up on your posts is that these posts use markdown and the asterisk is a special character in markdown. If you have a spare hour one day, I can highly recommend taking this Markdown Basics course. Besides being able to make your answers better and more readable here on the forums, markdown is used in other places such as GitHub. It's a great way to make your GitHub repo really stand out with some snazzy markdown :smiley: Thanks for helping out in the Community! :sparkles:

Hi Jennifer Nordell, thank you for your answer, I bookmarked the course, when I complete I will modify my comment. I too did not understand why my code was not showing up nicely like in other post.

Hi Mark Casavantes , I deleted the project by mistake, now I have downloded it again on my laptop and ran it before starting the coursework I did not modify anything and I get error messages from the prompter class. I have to say that I am stuck before even starting the coursework because I don't now what the error means. The first time I did the challenge I was working on another machine, I can't remmeber exatly what was different.

Good Afternoon Alexandra,

I think the problems with your code comes from these two lines of code.

System.out.printf("Your TreeStory:%n%n%s", tmpl.render(results));
for (String phrase : tmpl.getPlaceHolders()) {

I could not identify your problem based on the error statement. I am sorry I have not yet been able to find a solution to your problem.

I hope this is helpful.

Mark

Maybe it's as easy as just printing the story without formatting.
