Please read through my code and tell me what I'm missing. So frustrated. Videos move too quickly for me.

Here is my code for Gama.java, which is where I get an error message. Assuming that Hangman.java and Prompter.java do not contain errors.

Error is in line 25: error: cannot find symbol letter = validateLetter(letter);

symbol: method validateLetter(char)

Thanks!

[Code starts below] public class Game { public static final int MAX_MISSES = 7; private String mAnswer; private String mHits; private String mMisses;

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

private char validateGuess(char letter) { if (! Character.isLetter(letter)) { throw new IllegalArgumentException("A letter is required"); } letter = Character.toLowerCase(letter); if (mMisses.indexOf(letter) >= 0 || mHits.indexOf(letter) >= 0) { throw new IllegalArgumentException(letter + " has already been guessed"); } return letter; }

public boolean applyGuess(char letter) { letter = validateLetter(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; }

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