1 Oops Class Objects Inheritance Encapsulation Polymorphism Download Oops unit 2 free download as word doc (.doc .docx), pdf file (.pdf), text file (.txt) or read online for free. the document provides an overview of object oriented programming (oop), explaining its core concepts such as abstraction, encapsulation, inheritance, and polymorphism. Java is a true object oriented language and therefore the underlying structure of all java programs is classes. anything we wish to represent in a java program must be encapsulated in a class that defines the state and behaviour of the basic program components known as objects.
Unit 2 Oops Pdf Class Computer Programming Inheritance Object Multilevel inheritance: when a class is derived from another derived class, that is, the derived class acts as a base class, such a type of inheritance is known as multilevel inheritance. Introduction to inheritance, defining derived classes, single inheritance, multiple inheritance, multi level inheritance, hierarchical inheritance, hybrid inheritance. Inheritance is the oops feature which allows derivation of the new objects from the existing ones. it allows the creation of new class, called the derived class, from the existing classes called as base class. Unit – ii: inheritance: base class object, subclass, member access rules, super uses, using final with inheritance, method overriding, abstract classes interfaces: defining an interface, implementing interface, differences between classes and interfaces and extending interfaces.

Object oriented programming: inheritance object oriented programming paradigm: represent programs as a set of objects that encapsulate data and methods (state and behaviour) and pass messages between one another. 3. hierarchical inheritance : in hierarchical inheritance, one class serves as a superclass (base class) for more than one sub class.in below image, the class a serves as a base class for the derived class b,c and d. For example class c extends class b and class b. extends class a then this type of inheritance is known as multilevel inheritance. classes but supported through interface only. to reduce the complexity and simplify the. language, multiple inheritance is not supported in java. consider a scenario where a, b and c are three classes. When one object acquires all the properties and behaviours of another object, it is known as inheritance. it provides code reusability and establishes relationships between different classes.
