What is wrong? My hangman game wont work.

My Hangman game wont work.

When i compile the code like this in the console:

Javac Hangman.java

It does not return any errors, but when I try to execute the file like this:

java Hangman

My code wont run and work. I have no idea what is wrong. Can anyone look at my source code.

File Prompter.java:

import java.io.Console;
public class Prompter {
    private Game mGame;

    public Prompter(Game game) {
     mGame = game;
    }

    public void play() {
     while(mGame.getRemainingTries > 0 ) {
            displayProgress();
        promptForGuess();
        }
    }

    public boolean promptForGuess() {

     Console console = System.console();
     String guessAsString = console.readLine("Enter your guess: ");
     char guess = guessAsString.charAt(0);
     return mGame.applyGuess(guess);

    }

File Game.java :

public class Game {
    public static final int MAX_MISSES = 7;
    private static String mAnswer;
    public static String mHits;
    public String mMisses; 
    private int mManyTimes;
    public char letter;

    public Game(String answer) {
            mAnswer = answer;
            mHits = "";
        mMisses = "";
    }



     public boolean applyGuess(char letter) {
        boolean isHit = mAnswer.indexOf(letter) >= 0;

        if (isHit) {
             mHits = mHits + letter;
         } else {
                mMisses = mMisses + letter;
        }

        return isHit;
     }
     public static String howManyRight() {
         String hitler = "";
            for (char letter: mAnswer.toCharArray()) {
                 char display = '_';
                if(mHits.indexOf(letter) >= 0) {
                display = letter;
                }

The class that holds the main method:

public class Hangman {
    public static void main(String[] args) {
        Game game = new Game("treehouse");
        Prompter prompter = new Prompter(game);
        prompter.play();
    }
}

I tried to solve this problem without help but it didn’t work Thanks for advance :)

Hi Ibrahim,

When you say "it won't work", do you get any errors displayed at run time? Can you paste those into here?

And, as Geovanie pointed out, there's some missing code we could do with seeing too.

I get no errors. I don’t know what I’m doing wrong.

I forgot to copy the displayProgress() method but it is there.

public void displayProgress() {
        System.out.printf("You have: %d tries left. right right right!:  %s\n", mGame.getRemainningTries() ,mGame.howManyRight());
  }

OK, so what's the issue? You say "it won't run or work" - what happens when you run your code?

Steve.

Your code is incomplete i can't find the displayProgress method on the Prompter.java and the getRemainingTries method in the Game.java
