CODE HANGMAN

// 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.displayProgress();
}
}
CODE GAME
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; } }
public String getCurrentProgress() { String progress = ""; for (char letter : mAnswer.toCharArray()) { char display = '_'; if (mHits.indexOf(letter) >= 0) { display = letter; } progress += display; } return progress; }
CODE PROMPTER
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()); } }

3,376 PointsIt looks like you have one too many closing brackets at the end of the applyGuess function, which is closing the definition of your Game class. Move a closing bracket from the end of the applyGuess function to the end of the getCurrentProgress function and see if it works.

9,453 PointsThat fixed it! Most of my mistakes are misplaced brackets, I have to work on catching that. Thank you very much!
