why declaring Object of class Game as member variable instead of creating new instance with new keyword Game game= new Game(); and then we can use game variable to get applyGuess () method
what is the difference between these two approaches ?

15,583 PointsThis is the first part I interpret your question like : "Why " The reason he made it private is because of the encapsulation. Meaning Craig makes member variables private. The other reason is that it is not needed to make a new Game object. Everything that happens, needs to happen in the same Hangman match and not a new one .
What i also take from your question is : "Why is the private Game game added as a member variable in Prompter ?" The other reason is as follows : the Prompter handles the logic for the input for the Game and the display of it ( if you're not that far, it's comming up pretty soon ). The prompter like i said handles the input from the user. When the User gives input, it needs to check what it is. Whether its right or wrong falls outside of the scope of the prompter class. So now that game is a member variable, it can acces it and use the applyGuess function to determine wether it was a hit or a miss.
hoped this helped a bit Imran Asif . If ya need more explanation just tag me.
