My Code is All kinds of messed up

public class Hangman {

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

}
} 

import java.io.console;

public class Prompter{
  private Game mGame;

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

  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("Try to Solve: %s\n", mGame.getCurrentProgress());
}

}

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;
}
