I can not run my java code in workspaces.

import java.io.Console;
public class Prompter {
 private Game mGame;

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

 public void play() {
  while(mGame.mMisses.length() >= mGame.getRemainningTries()) {
    displayProgress();
    promptForGuess();
  }
 }

 public boolean promptForGuess() {

  Console console = System.console();

  String guessAsString = console.readLine("Enter your guess: ");
  //the guess variable gets the first letter of the input that the user inters in the guessAsString variable.
  char guess = guessAsString.charAt(0);
  // finaly the promptForGuess() method returns  the character the user inserted and in the same time 
  return mGame.applyGuess(guess);

 }

  public void displayProgress() {
    System.out.printf("You have: %d tries left. right right right!:  %s\n", mGame.getRemainningTries() ,mGame.howManyRight());
  }

}

public class Game {
  public static final int MAX_MISSES = 7;
  private static String mAnswer;
  public static String mHits;
  public String mMisses; 
  private int mManyTimes;
  public char letter;

  public Game(String answer) {
    mAnswer = answer;
    mHits = "";
    mMisses = "";
  }



  public boolean applyGuess(char letter) {
   boolean isHit = mAnswer.indexOf(letter) >= 0;

   if (isHit) {
    mHits = mHits + letter;
    } else {
      mMisses = mMisses + letter;
   }

   return isHit;


  }
  public static String howManyRight() {
    String hitler = "";
    for (char letter: mAnswer.toCharArray()) {
      char display = '_';
      if(mHits.indexOf(letter) >= 0) {
        display = letter;
      }
      hitler = hitler + display;
    }
    return hitler;
  }

  public int getRemainningTries() {
    return MAX_MISSES - mMisses.length();
  }
}

Here is the main file:

```java 

import java.io.*;
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();

    }
}
