Introduction
OOPS, Concepts or Object Oriented Programming
Concepts are most important. Without a plan about
OOPS concepts, one will not be capable of performing to
create systems in the object-oriented programming
model.
Let us know about the features of Object Oriented
Programming. Object Oriented programming is a
programming style which is combined with the concepts
like class, object, Inheritance, Encapsulation,
Abstraction, Polymorphism.

4. What is OOPS?
OOP method in Java are the essential
thoughts behind Java’s Object Oriented
Programming. They are an abstraction,
encapsulation, inheritance, and
polymorphism. Understanding them is key
to accepting how Java works. Object-
oriented programming makes easier for
programmers to structure and organize
software programs.

5. OOPS
Concepts
Four main OOP concepts in Java
1. Abstraction: Abstraction is the concept of covering the
internal details and characterize things in simple terms.
There are many ways to reach abstraction in object oriented
programming, such as encapsulation and inheritance.
2. Encapsulation: This is the process of keeping fields within a
class private, then giving connection to them via public
methods.
3. Inheritance: A main feature of object oriented programs
is inheritance. The capability to build classes that divides the
attributes and methods of existing classes but with more
specific features.
4. Polymorphism: This Java OOP concept lets programmers
make use of the similar word to mean different things in
different circumstances.

6. How OOP Concepts works in Java?

OOP, concepts in Java work by allowing programmers to create
elements that can be used again in various ways but still it keep
ups security.
How Abstraction Works: Abstraction as an OOP concept in
Java works by letting programmers create useful, reusable tools.
How Encapsulation Works: Encapsulation lets us re-use
functionality without jeopardizing security. It’s a powerful OOP
concept in Java because it helps us save a lot of time
How Inheritance Works: Inheritance is another labor-saving
Java OOP concept. It works by letting a new class adopt the
properties of another.
How Polymorphism Works: Polymorphism in Java works by
using a remark to a parent class to affect an object in the child
class.

Advantages of OOPs
OOP makes easy to understand and a clear modular structure
for programs.
Objects generated for Object-Oriented Programs can be used
again in other programs. Thus, it saves important
development cost.
OOPs implements the capability to simulate real-world
event much more efficiently.
OOPs makes development and maintenance easier.
OOPs supports data hiding, whereas in a method of
programming language a global data can be accessed from
anywhere.
