Remaining Tries not Decreasing

It stays at 7 tries. Tried all I could think of to make it work.

class Game{ public static final int MAX_MISSES = 7; private String answer; private String hits; private String misses;

public Game(String answer){ this.answer = answer; hits = ""; misses = "";

} boolean applyGuess(char letter){ boolean isHit = answer.indexOf(letter) != -1; if (isHit){ hits += letter; }else{ hits += misses; } return isHit; }

public int getRemainingTries(){ return MAX_MISSES - misses.length(); }

public String getCurrentProgress(){ String progress = ""; for (char letter : answer.toCharArray()){ char display = '-'; if (hits.indexOf(letter) != -1){ display = letter; } progress += display; } return progress; }

}

public class Hangman {

public static void main(String[] args) { // Your incredible code goes here...

Game game = new Game("treehouse");
Prompter prompter = new Prompter(game);
while (game.getRemainingTries() > 0){
    prompter.displayProgress();
    prompter.promptForGuess();    
}

} }

The formatted code looks much better! But after the change, both conditions are doing the same thing. That's still not quite what I was suggesting:

    if (isHit){
      hits += letter;
    }else{
      hits += letter;  // should this be "misses += letter;" instead?
    }

For "getRemainingTries()" to decrease, you must add to "misses"; but that doesn't seem to be done anywhere.

Perhaps the issue is in this section of the "applyGuess" method:

  if (isHit) {
    hits += letter; 
  } else {
    hits += misses;  // should this have been "misses += letter;" instead?
  }

And when posting code, use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down:   Or watch this video on code formatting.

Thanks for the suggestion on formatting my code. I never knew how to do it until now. Your suggestion above I believe is in my code.

class Game{
  public static final int MAX_MISSES = 7;
  private String answer;
  private String hits;
  private String misses;

  public Game(String answer){
  this.answer = answer;
  hits = "";
  misses = "";

  }
  boolean applyGuess(char letter){
    boolean isHit = answer.indexOf(letter) != -1;
    if (isHit){
      hits += letter;
    }else{
      hits += letter;
    }
    return isHit;
  }

  public int getRemainingTries(){
    return MAX_MISSES - misses.length();
  }

  public String getCurrentProgress(){
    String progress = "";
    for (char letter : answer.toCharArray()){
      char display = '-';
      if (hits.indexOf(letter) != -1){
        display = letter;
      }
      progress += display;
    }
    return progress;
  }

}

I just saw that and fixed it. Thanks greatly appreciated.
