Hi Tony,

This exception occurs because the method applyGuess is not returning a boolean value. The work around is to change the return value to void.

public void applyGuess(char letter) {

Best Regards

Actually, the appropriate fix is to just return isHit and leave boolean as the expected return value. I had to restart java-repl for this to work.

public boolean applyGuess(char letter) {
    boolean isHit = mAnswer.indexOf(letter) >= 0;
    if (isHit) {
      mHits += letter;      
    } else {
      mMisses += letter;
    }
    return isHit;
  }

I had to rewatch the video and verify that Craig does type return isHit;. It's just not on the screen for very long - my first time following along, I was busy typing and completely missed it.
