2. WHAT IS OBJECT ORIENTED
PROGRAMMING?
 Collection of objects
 It focus on data, not on the procedure
 In oops most important thing is called object
 Objects consist of attributes and methods

3. BASIC CONCEPTS OF OOPS
Manojkumar
Basic
concepts
Abstraction Object Class Inheritance Polymorphism

4. ABSTRACTION
 Represents only essential features
 Hiding all implementation details
Example:
Manojkumar

5. OBJECTS
 Object is an instance of class
 Object are basic run-time entities in object oriented
programming
Example
Manojkumar

6. HOW TO DECLARE AN OBJECT?
Syntax:
class_name Object = new class_name();
Example:
student mark = new student();
student-class name
mark-object name
Manojkumar

7. CLASS
 Class can be defined as an entity in which data and
functions are put together
 Class concept is similar to the concept of structures
in C
Manojkumar

8. HOW TO DECLARE A CLASS?
Manojkumar
Class class_name
{
//variables
//methods
}
Class student
{
int marks,total;
void display();
}
Syntax Example
Inside the body of the class there are two keyword used
1.private
2.public
These are called access specifiers

9. ENCAPSULATION
 Binding of data and method together in a single unit
called class
Manojkumar

10. INHERITANCE
 obtaining the data members and methods from one class
to another class is known as inheritance.
Manojkumar

11.  the class which is give data members and methods is
known as base or super or parent class.
 The class which is taking the data members and methods
is known as sub or derived or child class.
Manojkumar

12. POLYMORPHISM
 It take more than one form and refers to an
operation exhibiting different behaviors in different
situations
Manojkumar
