      if (mHits.indexOf(letter) >= 0) {
        display = letter;
    progress += display;
    return progress;
  public int getRemaningTries() {
    return MAX_MISSES - mMisses.lenght();
public class Hangman {

    public static void main(String[] args) {
        // Enter amazing code here:
      Game game = new Game("treehouse");
