INTRODUCTION
TO OBJECT-ORIENTED PROGRAMMING
Object-Oriented Programming is also called OOP.
Definition
:
The Object-oriented progamming (OOP) is a programming
methodology that helps to organize set of instructions in a proper sequence to
develop program or software.
The
Great advantage of OOP
The main and great advantage of OOP are to make complex
software faster to develop and easier to maintain.
It also enables the easy reuse of code by applying simple
and widely accepted rules of OOP principles.
so...
WHAT
IS THE PRINCIPLES OF OOP ?
There are four types of OOP Principle -
1)Abstraction
It is an act of representing essential feature without
including background detail and explaination.
2)Encapsulation
The act in which data and method are combined together in
the form of single unit is known as encapsulation.
For
example :
You are very much familiar with medicines. A capsule is
also a medicine which contain combination of many medicine in the form of
powder(encapsulated form of medicine). Same as when many object are
combined/encapsulated to form a single object is called encapsulation.
3)Inheritance
When one class requires the property of other class is
called inheritance.
Base
Class : The existing class whose properties
are inherited by some other class is known as base class or super class.
Derived
Class : The class that acquire the property
from existing class is known as derived class or sub class.
For
example :
lets take a example from real world please dont mind
suppose your father is a super class and you as child is sub class and its
obvious that some properties or habits of your father is inherited to you
so..thats called inheritance.
4)Polymorphism
When one class is having many form means when one
function behave differently in a same class.
For
example : The color class
may have a method named Paint()
that can be used to paint various color as shown...
