Method Overriding

A subclass inherits the methods from the super class and redefines it by filling it with its own instructions. This is done by defining methods in the sub class that has the same name arguments and same return type as the super class’s methods.

This is one method of achieving polymorphism.

Methods

There are two types

Instance Methods

They work with the  object instance. An instance method is called by referring to an object name.

Ex:

            Acc1.deposit (200);

Class Methods

A class methods works on the class not on the objects. It can be called by referring to class name. Class methods are defining by using keyword static.
