An error with Prompter.java is preventing Hangman.java from compiling, but I'm following the video. Did I miss something

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);
  }
}

When I go to compile Hangman.java I get the following error message: <p>./Prompter.java:10: error: missing method body, or declare abstract
public boolean promptForGuess(); {
^
./Prompter.java:14: error: return outside method
return mGame.applyGuess(guess);
^ </p>

It's a little hard to tell because you aren't providing us with your error or your hangman.java. My first question is, does your apply Guess method return a boolean?

EDIT: After review I found the error

public boolean promptForGuess(); {

You have a semicolon after your method which should not be there. Semicolons in java are used to end statements.

public boolean promptForGuess() {

Would be your proper format. Hope this helps Happy Coding!

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("We got a hit!");
    } else {
      System.out.println("Whoops that was a miss");
    }
  }

}

In game.java, my applyGuess method ends with the line return isHit;
