I have a newbie question. If I have some global variables that are shared by two classes or more how can I have them in a separate file so that any class can read and update them. Is this possible without using Interfaces?

Yes, since
interfaces variables are all implicitlystatic, so each of these variables has only one instance in the jvm.However, a better way to do it [in my opinion] would probably be having them declared in some singleton class and using it.
