java.util.NoSuchElementException

I have looked and looked at my code and tried looking at other questions about this but I can't understand why I keep getting this error. Any help is much appreciated. I don't want to move ahead in the course until I understand what's happening.

Here's what I have in each file.

Hangman.java file:

public class Hangman {

public static void main(String[] args) {
    // Enter amazing code here:
  Game game = new Game("treehouse");
}

}

Prompter.java file:

public class Prompter { }

Game.java file:

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

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

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

Where are you running the code?

I copy-pasted your code and compiled and ran it without getting the java.util.NoSuchElementException:

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

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

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

public class Hangman {

    public static void main(String[] args) {
        // Enter amazing code here:
        Game game = new Game("treehouse");
    }

}

public class Prompter {
}

Weird. I'm running it in Workspaces.

I uploaded your code onto one of my workspaces https://teamtreehouse.com/workspaces/15935202

use "javac Hangman.java" to compile the code. and "java Hangman" to run it.

The program doesn't really output anything, but it works fine.

Even though I had no errors, I was able to get it working in the repl after: a.) Getting out of repl (CTRL + C) b.) Compiling it (javac Hangman.java) c.) Getting back into the repl and following the steps again from load

Sometimes workspaces is a little wonky.
