The document outlines the core concepts of Object-Oriented Programming (OOP), including classes, objects, encapsulation, abstraction, inheritance, and polymorphism. It describes how a class is a collection of attributes and methods, while an object is an instance of a class with its own state and behavior. The document emphasizes encapsulation as wrapping variables and methods, abstraction as hiding unnecessary details, inheritance as creating new classes from existing ones, and polymorphism as allowing one action to be performed in various forms.

1. OOPS Concept

2. Concept of OOPs
• Class
• Object
• Encapsulation
• Abstraction
• Inheritance
• Polymorphism

3. Class
• The class can be defined as a collection of attributes and
member function.
• For example: if you have an employee class, then it
should contain an attribute and method, i.e. an email id,
name, age, salary, etc.

4. Object
• Object is an instance of a class
• The object is an entity that has state and behavior.
• It may be any real-world object like the mouse, keyboard,
chair, table, pen, etc.

5. Encapsulation
• Encapsulation is a
mechanism of
wrapping the
variables and
methods together
as a single unit.

6. Abstraction
• Abstraction is the concept
of object-oriented
programming that "shows"
only essential attributes
and "hides" additional
information. The main
purpose of abstraction is
hiding the additional
details from the users

7. Inheritance
• Inheritance is a process of
creating a new class(Child
class) from existing
class(Parent Class)

8. Polymorphism
• Poly means ‘many’, and
morph means ‘form’
• Polymorphism allows us to
perform a single action in
different ways
• i.e., Single Entity can
behave in different way
