ClassName obj = new ClassName(); Here new ClassName() is the object and obj is the reference variable pointing to that object. Some good practices- 1) class name should start with an upper case letter. Eg- class Game{ } 2) variable names should follow camel case. Eg- maxAmountOfPlayers. 3) camel case would apply for methods as well. Eg- openGame(); I have modified your code. It might take a little time to sink in but you will get there eventually. Just read and practice more. https://code.sololearn.com/c3g0225iQGSy/?ref=app

yahel interface cannot have a constructor. Why? because it is not a class. So you cannot create an instance of it. The class implementing the interface must provide all the details.

It is nothing but an object of the class. Instead of using an interface you can replace it with an abstract class which would make things easier.
