Subclassing
Introduction
Subclassing is one of the significant features of OO programming, which greatly increases the reusability of classes and also minimizes duplication of code. A subclass usually inherits some properties from a super class. A superclass consists of common features that can be extended over subclasses. It is extensively used in object oriented programming because of the reusability that can be achieved. Superclass and subclass are commonly called base and derived class. The relationship between a subclass and superclass can be represented by a simple UML diagram as shown below.
