Hi Jagmeet,

The Prompter method inside the Prompter class is an example of a constructor.

You use constructors to build the instance of the class when you create one. In this case, since the Prompter class instances hold a member variable that is a Game object, the constructor is receiving an instance of Game as a parameter. The parameter for the constructor Game game tells you that a Game object called game has been passed in. That instance is then assigned to the member variable of the Prompter instance, called mGame.

So, you create an instance of the Prompter class by sending a Game object to the Prompter() constructor which is then stored in the member variable mGame.

I hope that helps!

Steve.
