List three advantages of creating a useful, extendable superclass.
What will be an ideal response?
Subclass creators save development time because much of the code needed for the class has already been written.
Subclass creators save testing time because the superclass code has already been tested and probably used in a variety of situations. In other words, the superclass code is reliable.
Programmers who create or use new subclasses already understand how the superclass works, so the time it takes to learn the new class features is reduced.
When you create a new subclass, neither the superclass source code nor the translated superclass code is changed. The superclass maintains its integrity.
