    So the main becomes "useless" and used just to declare other classes?

    My book struggles to elaborate on variables(double,int,String) and you elaborate everything in 6 min.You express things pretty well.

    @thenewboston when i use multiple classes it ask me to choose server, how can i fix this?

  22. Xydez Avatar

    A tip: Make the first letter of your class name uppercase, This is so you can do Main main = new Main(); Instead of main mainObject = new main(); I don't think you can have the same name for your class and your class object/reference.

  27. Sgt$yed Avatar

    How would you call a variable from another class? Let say I have an "int h = 25;" in one class and i want to call it in another class. How would I do that?
