It utilises class hierarchy, including superclasses and subclasses which allow for reusability and the extension of existing classes (Wu, 2010, p. 23). Static and Dynamic polymorphism ( Runtime Polymorphism ) . Encapsulation is intrinsically linked to modularity. This mechanism actually inherits the fields and methods of the superclass. Ethnicity, polymorphism, encapsulation, and abstraction are the four basic features. OOP allows decomposition of a problem into a number of entities called objects and then builds data and functions around these objects.
