Basics of Object-Oriented Programming.

2.  CLASS
 OBJECT
 ABSTRACTION
 ENCAPSULATION
 INHERITENCE
 POLYMORPHISM

3.  Object Oriented Programming (OOP) is a
programming model where programs are
organized around objects and data rather
than action and logic.

4.  Class is a user defined data type, that has
some general identity, state and behaviour.
 A class will never occupy any memory space
and hence it is only a logical representation
of data.
 In OOP languages it is mandatory to create a
class for representing data.

5.  Object is the basic unit of object-oriented
programming.
 Object is an instance of class, that has an
identity, state and behaviour.
 Each instance of an object can hold its own
relevant data.

6.  Abstraction means showing essential features
and hiding non-essential features to the user.
 Abstraction means “FRONTEND”.
 Abstraction lets us focus on what the object
does instead of how it does it ?

7.  Encapsulation = En + capsule +ation
( Everything In a single capsule).
 Wrapping up a data member and a method
together into a single unit is called
Encapsulation.
 Its hide the data for security such as making
the variables public, private and protected.

8.  When a class includes a property of another
class it is known as inheritance.
 Inheritance is a process of object reusability.
 New methods and attributes can be created in
the new class, but don’t affect the parent
class’s definition

9.  Poly means many one form can perform
differently in different scenarios. We will
get different results in different scenarios.
 "Many forms of a single object is called
Polymorphism."
 Polymorphism mainly happens in runtime
only.

10.  1.Abstraction:- We press the button and
result displays on screen.
 2.Encapsulation:- There is number of circuits
available but they all are binded in a single
frame.
 3.Inheritence:- Android 10 inherited by Pie.
 4.Polymorphism:- Before & after semester
examinations.
