What is Object Oriented Programming (OOPs)

 

o   What is Object Oriented Programming (OOPs)? Define The Major and Minor Elements of  OOPs ?

Ans:-   Object oriented programming is an approach to program organization and development, which attends to eliminate some of the pitfalls of conventional programming features which several new concepts. It is a new way of organizing and developing programs as nothing to do with any particular language.

                OOPs in Java is to improved code readability and reusability by defining a java program efficiently.

The main principal of OOPs are ‘Abstraction’ , ‘Encapsulation’, ‘Inheritance’ and ‘Polymorphism’ . This Concept aim to implement real world entities in program.

 

            *Major Elements of OOPs Concept: -

The major elements in OOPs are –

                                                                                                                                  i.            Abstraction

                                                                                                                                 ii.            Encapsulation

                                                                                                                               iii.            Modularity

                                                                                                                               iv.            Hierarchy

Abstraction :-

                                     Abstraction refers to the act of representing essential features without including the Background detail’s explanation.

Example:-  When a class student is design the attributes enrolment no. , name, course  and address are included , Where characterize like pulse-rate and size of shoe are eliminated.

 Encapsulation :-

                                     The Wrapping up a data and methods into a single unit is known as encapsulation. The data is not usable to the outside world, and only those methods which are wrapped in the class can access it.
