Inheritance

The Benefits of Inheritance

. Subclasses provide specialized behaviors from the basis of common elements provided by   the superclass. Through the use of inheritance, programmers can reuse the code in the   superclass many times.

. Programmers can implement superclasses called abstract classes that define "generic"   behaviors. The abstract superclass defines and may partially implement the behavior but   much of the class is undefined and unimplemented. Other programmers fill in the   details with specialized subclasses.
