Object Oriented Programming Through Java by Pearson

1.16 Basics of Object-oriented Programming

Now when there are several subclasses implementing a function, it is critical that correct

function of correct derived class needs to be invoked. That is, at run time, correct function has

to be invoked through a function call. The feature that ensures this correct run time binding of

function is called dynamic binding. Polymorphism means to ensure that objects of base class

behave correctly and as planned. For example, CSESTUDENT must use St

udents Work()

and ECESTUDENT must use its own Work() and so on and so forth.

Inheritance solves the problem of reusability. That is, derived class can access all the data

members and function members of base class that are declared as protected. ...
