Little help, please?

public class Hangman {    
  public static void main(String[] args) {
    // Enter amazing code here:
    Game game = new Game("treehouse");
    Prompter prompter = new Prompter(game);
    boolean isHit = prompter.promptForGuess();
    if (isHit) {
      System.out.println("You got a hit!");
    } else {
      System.out.println("Whoops, you missed!");
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 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) {
      mAnswer += letter;
    } else {
      mMisses += letter;

I get an error from the console telling:

./Game.java:18: error: missing return statement                                                       

Please advise.

The error is telling you exactly what you need to know. you are missing a return statement. your function definition is

public boolean applyGuess(char letter)

which means you will be returning a boolean. However, you are not returning anything in the function. To solve this problem, you either have to change boolean to void, which means you don't want to return anything. Or you have to add

return isHit;

to the end of the applyGuess function, assuming you want to return the value of isHit.
