Classes Inheritance Packages Interfaces Pptx Concept of inheritance inheritance, which is a form of software reuse in which a new class is created by absorbing an existing class's members and embellishing them with new or modified capabilities. If a class inherits the data member and member function from more than one base class, then this type of inheritance is called multiple inheritance. (java will not support directly but it is possible using “interface”). Parent vtu program to demonstrate interfaces interfaces uses all or nothing paradigm to implementing class. alternative – make class abstract class interface. Why use inheritance in java? method overriding: if subclass (child class) has the same method as declared in the parent class, it is known as method overriding in java. in other words, it is used to provide the specific implementation of a method which is already provided by its superclass.

Objects can take on many forms in an object oriented program. the form of the class in which they are declared. the form of any parent class in the class’ inheritance hierarchy. ‘object’ is a parent class whether declared or not (always at the top of the inheritance hierarchy).
