Actually, you're not referring to a superclass field in this instance. Your
subclass inherits all the methods and variables of the superclass, so _test
is a member of the object you create using SubClass.
You need to use super when you have overridden a method or variable. For
example, if you have an Init() method in both, and you want to run the
superclass's Init() first, you would call super.Init();
Otherwise, you treat inherited methods and vars as if they were part of the
subclass--which they are. They're just inherited, not declared.
Cordially,
Kerry Thompson
