I need some help with java that has errors.

import java.io.Console;

public class Prompter{
  private Game mGame;

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

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

  public boolean promptForGuess() {
    Console console = System.console();
    String guessAsString = console.readLine("Enter a letter: ");
    char guess = guessAsString.charAt(0);
    return mGame.applyGuess(guess);
 }
  public void displayProgress() {
    System.out.printf("You have %d tries left to solve: %s\n", 
                      mGame.getRemainingTries(),
                      mGame.getCurrentProgress());
  }
}

public class Game{
  public static final int MAX_MISSES = 7;
  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;
  }
  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");
      Prompter prompter = new Prompter(game);
      prompter.play(); 
      }
    }
