6. Object oriented program
Oop is an approach that provide
modularizing programs by creating
partitioned memory area for both data
and functions that can be used as
template for creating copies of such
modules on demand.

7. • Object oriented paradigm
data
mm

8. • Emphasis on data rather than procedure
• Programs are divided into what are called
Object
• Data is hidden and cannot accessed by
external function
• Object communicate each other through
method
• New data and method can be added
whenever necessary

9. Object
• Basic runtime entities
• State and behavior of the basic program
Components
Eg:person,place…..
• Object condain data and code to manipulate
data
• Compination of data and method make up an
object

10. Class
• User defined data type
• Once a class defined we create variables,these
Variable are termed as instances of classes
which are actual object
• Collection of object of similar type

11. Method
A class without method has no life,object
created by such class cannot respond to any
messages
• Method that are necessary for manipulating
data contained in class.

12. Data abstraction
Wrapping up of data and method into a single
unit
Data Encapsulation
Representing essential feature without including
details or explanation

13. • Inheritance:
Object of one class acquire the property of another
class
Reusability
We can additional features to an existing class without
modifying it
Deriving new class from existing class

14. polymorphism
• Ability to take more than on form

15. Class sum{
Void add (int a,int b)
{
System.out.println(“+(a+b));
}
Public static void main( String args[])
{
sum obj=new sum;
Obj.sum(10,5)
}
