Cannot find symbol error

Have been following Craig in coding the Hangman game but got a Cannot find symbol error. What does this error require coz I have been trying but it aint working. Below is the code:

import java.util.Scanner;

class Prompter{
private Game game;

  public Prompter(Game game){
  this.game = game;
  }
  public boolean promptForGuess(){
  Scanner scanner = new Scanner(System.in);
    System.out.print("Enter a letter:  ");
    String guessInput = scanner.nextLine();
    char guess = guessInput.charAt(0);
    return game.applyGuess(guess);
  }
}

Hello Brighton,

Would you mind sharing your code for Game.java and Hangman.java as well?

Hello Brighton,

Thank you for providing your code for the other files. It seems you're Game class in Game.java is missing the applyGuess method that Prompter.java depends on. The error is happening on the last line of promptForGuess.

return game.applyGuess(guess);

Once you add this method to the Game class, you should be able to compile without errors. Follow along in this video Storing Guesses to see Craig add this method in Game.java.

class Game {
  private String answer;
  private String hits;
  private String misses;

  public Game(String answer){
    this.answer=answer;
  }

  public boolean applyGuess(char letter) {
    boolean isHit = answer.indexOf(letter) != -1;
    if (isHit) {
     hits += letter; 
    } else {
      misses += letter;
    }

    return isHit;
  }
}

I hope this helps.

Where is the applyGuess() method? You call it but don't have it in your code.

Thanx Justin, below are the respective codes

Game.java code

class Game{
private String answer;

  public Game(String answer){
  this.answer=answer;
  }
}

Hangman.java code

public class Hangman {

  public static void main(String[] args) {
    // Your incredible code goes 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("Oops missed!");
    }
  }
}
