Constructor: You used Prompter inside Prompter. Huh?

I don't get it.
Craig constructed "Prompter" inside some class called "Prompter".


I get this: Game game = new Game. --> Its a new and unique instance of the Game class. but now Craig is putting one class inside the same class with the very same name.

Hello, are you talking about this line of code?

public class prompter{ // class name

public prompter(String sForString){

// world changing code.



Java creates a default constructor for all classes you just cant see it. In order for you to create a constructor you MUST use the name of the class your creating the constructor in. If it accepts a parameter you must pass it something according to its type. Further more constructors are made to initialize member variables we have created in our class.

when you use this line of code: prompter promptME = new prompter(); You are creating an instance of the class and calling a constructor automatically. Constructors are a little confusing but with practice of using methods and constructors you will start to see the difference and the importance of their uses.
