Java Java Objects (Retired) Creating the MVP Current Progress

Not displaying correct guesses

When running hangman in console I get:

Try to solve: --------- Enter a letter: t We got a hit! Try to solve: ---------

It seems my progress variable in getCurrentProgress() in Game.java but I can't find problem code. I've compared it several times to Craig's code in the video, but I'm missing something.

Can anybody see where I went wrong?

Here's the code for Game.java

public class Game {
  private String mAnswer;
  private String mHits;
  private String mMisses;

  public Game(String answer) {
    mAnswer = answer;

    mHits = "";
    mMisses = "";

  public boolean applyGuess(char letter) {
    boolean isHit = mAnswer.indexOf(letter) >= 0;
    if (isHit) {
      mHits += letter;
    } else {
      mMisses += letter;
    return isHit;

  public String getCurrentProgress() {
    String progress = "";
    for (char letter : mAnswer.toCharArray()) {
      char display = '-';
      if (mHits.indexOf(letter) > 0) {
        display = letter;
      progress += display;
    return progress;

And here is the code for Prompter.java

import java.io.Console;

public class Prompter {
  private Game mGame;

  public Prompter(Game game) {
    mGame = game;

  public boolean promptForGuess() {
    Console console = System.console(); // calling console() on System will
                                        // return a console object
                                        // This requires a package: java.io.Console
    String guessAsString = console.readLine("Enter a letter:  ");
    char guess = guessAsString.charAt(0);
    return mGame.applyGuess(guess);

  public void displayProgress() {
    System.out.printf("Try to solve: %s\n", mGame.getCurrentProgress());

And finally, Hangman.java

public class Hangman {

    public static void main(String[] args) {
        // Enter amazing code here:
      Game game = new Game("treehouse");
      Prompter prompter = new Prompter(game);
      boolean isHit = prompter.promptForGuess();
      if (isHit) {
        System.out.println("We got a hit!");
      } else {
        System.out.println("Whoops that was a miss");


Any feedback would be appreciated.

Hi Jason

I think your correct and the issue lies with your getCurrentProgress method. If you pass in a different char such as 'e' does it work?

I'm guessing it does and in that case the issue lies with the line below.

if (mHits.indexOf(letter) > 0) {

The char 't' is at index 0 so this test would fail and the letter 't' won't be assigned to the display variable. It should be greater than or equal to. So your code should look like:

if (mHits.indexOf(letter) >= 0) {

Hope it helps!


Thanks, Stephen. That worked! I need to pay attention to details. I got caught doing the same thing in the coding challenge following the video.
