very real time scenario from the object oriented programming are1) encapsulation.2 ) Abstraction3) Inheritance4)Polymorphism
FIRST WE WILL TAKE ABOUT ENCAPSULATION
it states that wrapping of code and data into a single class is called as encapsulation
general example: like we wrap chapati(OR) ROTI in ALUMINIUM FOIL .
SECOND ABSTRACTION
it states that hiding of complex data and showing the essential things.
general example: while driving a car we just brother about the car steering,clutch,break,accelerator.
we dost not brother about how the gear is shifting up and how the internal mechanism is going on move the car .
THIRD INHERITANCE
it states that child class acquire the properties of parent class
it s used for code re usability.
FOURTH POLYMORPHISM
it states that one to many form
general example : one person can play different roles he can play a role of father,husband,son,brother ect.
pillars of object oriented are :Abstraction,Encapsulation ,Inheritance ,Polymorphism those four part in the core of object oriented if we want describe those four parts we will say :1-Abstraction is a process of exposing essential feature of an entity
while hiding other irrelevant detail. like when we want to have many persons (ibrahim, joseph ..etc but they have the same aspect human we will say they ahh have an abstract source it's called abstract class2-Encapsulation is when you hide your modules internal data and all other implementation details/mechanism
from other modules.3-Inheritance
The ability of creating a new class
from an existing class. or to get same properties from one source like apple and orange bothe heritat from one source is fruits
-4. Polymorphism
A subclass can define
its own unique behaviour and still share the same functionalities or behavior of its
parent/base class
exemple
apple +orange = fruits
