In "... class ClassM extends ClassU..." where ClassM is the Main (lead-off) class, I found thru the debugger that ClassU executes first. I need for ClassU to access ClassM's getters/setters but I don't know how to do this. I can't instantiate ClassM from ClassU so how ?

How about the reverse? Can ClassM reach ClassU's getter/setters, how?

Thank you!

PS in Java class these types of issues were never discussed, and I didn't know enough to ask
