java.util.NoSuchElementException -- I am baffled

I have looked through all of the threads but have not turned up any reasons for why I am receiving this error. Here is my code...

public class Game { private String mAnswer; private String mHits; private String mHisses;

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

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

Here is what I'm running in the REPL that results in this error: treehouse:~/workspace$ java-repl Welcome to JavaREPL version 303 (Java HotSpot (TM) 64-Bit Server VM Java 1.8.0_65) Type expression to evaluate, :help for more options or press tab to auto-complete. java> :load Game.java Loaded source file from Game.java java> Game game = new Game("treehouse"); java.util.NoSuchElementException java>

I cannot understand why I am hitting this error in the REPL. Any guesses?

In two places you have mHisses, but in the constructor you have mMisses. As you code stands, it shouldn't even compile. But if you change the two mHisses to mMisses it will compile (and run if you call if from REPL, a client program, or a main method added to Game.

The variable in mMisses in your constructor was either never initialized or mistyped.
