Java Java Objects (Retired) Creating the MVP Prompting for Guesses

Why are we making a "private Game mGame" in the prompter class, then making a constructor "Prompter(Game game)" ?

Why are we making a "private Game mGame" in the prompter class, then making a constructor "Prompter(Game game)" ? Don't we already have a constructor for Game in the Game class? Shouldn't we just say "Game game = new Game"?

Thanks,

Tony

The Prompter constructor is for the Prompter class and it takes a Game object to instantiate the Prompter object.

The Game constructor is called when the mGame variable is initialised, I presume.

So, within the Prompter initialiser, it'll assign the game instance passed in to it to initialise mGame with game.

I hope that makes sense! I've not done that course so have no working knowledge of the code but do understand why that might be confusing. Think about instances, multiple versions, rather than just one use - the whole class object thing makes more sense when you "think big".

Cool! Keep at it; doing it every day makes it better.

Same with coding.
