When is the applyGuess method actually called?

The previous code actually called the applyGuess method when the statement return game.applyGuess(guess); ran. Now it doesn't seem like method is actually getting called to run, isHit is just being set equal to that method with guess as the parameter. Does the applyguess method execute when isHit is set equal to it? If so that feels weird that you don't really seem like you are calling the method. 

public boolean promptForGuess() {
 Scanner scanner = new Scanner(System.in);
  System.out.print("Enter a letter:  ");
  String guessInput = scanner.nextLine();
  char guess = guessInput.charAt(0);
  boolean isHit = false;
  try {
    isHit = game.applyGuess(guess);
  } catch(IllegalArgumentException iae) {
    System.out.println(iae.getMessage());
  }

  return isHit;
}

It's getting called in the try block. You might be mixing up the concept of passing a function as an object like you can in JavaScript. In Java, this is just a function call that has its boolean return value assigned to the variable isHit.
