What is the object oriented programming (OOPs)
What is the object oriented programming (OOPs):
The java and C# are object – oriented programming languages. The OOPs refer to the programming base on the object. OOPs have many features like Polymorphism, Abstraction and Encapsulation etc.
Why the programmers use Object oriented programming concept:
A main importance of OOPs
is to remove some of the flaws encountered with the procedural approach.
In OOPs data is treated as a critical element and does not
allow it to flow freely. Is bounds data closely to the functions that operate
on it and protects it form accidental modification from outside functions.
Oops allows the decomposition of programs in to a numbers of
entities called objects and the built data and function around the objects. The
major advantages of object oriented programming are code re-usability.
Introduction of Object -oriented programming(OOP):
Object –oriented programming (OOP) is a programming language model organized around
"Objects" rather than "actions" and data rather than
logic. Historically, a program has been
Viewed as
a logical procedure that takes input data, processes it, and produces output data.
The first step in OOP
is to identify all the objects you want to manipulate and how they relate to each
other, an exercise often known as data modeling. Once you've identified an object, you generalize it as a
class of objects and define the
kind of data it contains
and any logic sequences that can manipulate it. Each distinct logic
sequence is known as a method. Areal
instance of a class is
called an “object” or an “instance of a class”. The
object or class instance is what you run
in the computer. Its methods
provide computer instructions and
the class object characteristics provide relevant data. You communicate with objects and they communicate with each other.
Important features with OOPs are:
- Classes and Objects
- Inheritance
- Polymorphism
- Encapsulation
