Answer 1

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.

Answer 2

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.

Answer 3

Avinesh 🙏🏼👍🏻 , what does "instance" mean in java?

Answer 4

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.

Answer 5

Can you give me an example for object of class?

Answer 6

Avinesh alright, thanks!
