2. Object means a real word entity such as pen,
chair, table etc. Object-Oriented Programming is a
methodology or paradigm to design a program
using classes and objects. It simplifies the
software development and maintenance by
providing some concepts:
Object
Class
Inheritance
Polymorphism
Abstraction
Encapsulation
Object-Oriented Programming

3. Encapsulation is one of the fundamentals of
OOP (object-oriented programming). It refers
to the bundling of data with the methods that
operate on that data. Encapsulation is used to
hide the values or state of a structured data
object inside a class.

4. Encapsulation helps us in binding the
data(instance variables) and the member
functions(that work on the instance variables) of a
class.
Encapsulation is also useful
in hiding the data(instance variables) of a class from
an illegal direct access.
Encapsulation also helps us to make a flexible
code which is easy to change and maintain.

encapsulation

5. Importance Of Encapsulation
 To hide the internal implementation details
of the class
 Can safely modified the implementation
without worrying breaking the existing
code that uses the class
 Protect class against accidental/ willful
stupidity
 Keeps class tidy by keeping the visible
fields to aminimum
 Easier to use and understand

6. Benefits of Encapsulation
Provides data hiding
Reusability
Code can be modified without
breaking the code.
Hiding implementation details
reduces complexity.

7.  Encapsulation draws a boundary
around a s et of data and
method.
 This allows a developer to use the
code without having to know how
it works, but with what input data
and its input data range and with
what it returns.
Maintainability

8.  Makes long term development
easy.
 Updates can be made by changing
the encapsulated part without
changing the input and output
formats.
Extensibility

9.  Encapsulation makes
the code easier to
visualize.
 This means codes can be
arranged “visually” before
implementing.
