import java.io.Console;
public class Prompter {
private Game mGame;
public Prompter(Game game) {
mGame = game;
}
public boolean promptForGuess() {
Console console = System.console();
String guessAsString = console.readLine("Enter a letter: ");
char guess = guessAsString.charAt(0);
return mGame.applyGuess(guess);
}
}

It is important that the method is told what type of parameter is being passed in. That's what the initial Game is doing. The second game is just a name - it is unrelated to any data type; it could just as easily be called steve.
As it is, the method knows that it is going to receive an instance of the Game class as a parameter and that instance can be referenced by using the variable name game.
I hope that makes sense!
Steve.

18,813 PointsThat makes sense now, I compared it to
public Game(String answer) {
mAnswer = answer;
mHits = "";
mMisses= "";
}
and here too, it says Game takes an answer paramater of the String class.
Thanks for the enlightment, Could you tell me what is a Symbol when reffering to Java language?

Courses Plus Student 1,241 PointsI realize this is an old thread, but generally speaking I'd just like to mention that a symbol (in Java) is pretty much any word that's found in your code. If Java says it doesn't recognize a "symbol" then it doesn't know what the word means. Usually this happens because you haven't defined a variable.
Let's say you type
lobsterWords = "I like lobster";
but you never actually created a String called lobsterWords. You would probably get a "symbol" error because Java doesn't yet know what lobsterWords is. It could be an int or a String or a keyword. Java doesn't know until you define the variable.
