What are object oriented Programs?

Answer 1

There are two types of programmes related to objects that i know.

Pradip: object base means : realted only with object where u can find the encapsulation ,abstraction data hiding is possible but Inheritance,polymorphism, wil not be possible in case of object base programme. all are core object oriented programming.

Answer 2

THE OBJECT ORIENTED PROGRAMMING APPROACH IS ADOPTED TO REDUCE COMPLEXITY IN LARGE PROGRAMS THROUGH ABSTRACTION.

ABSTRACTION:

EG: WE DON SEE A CAR AS A COLLECTION OF THOUSANDS OF PARTS BUT AS A SINGLE OBJECT. ONCE WE ARE INSIDE IT WE KNOW A BIT MORE ABOUT IT BUT WE STILL NEED NOT KNOW ITS ENGINE WORKINGS UNLESS WE ARE THE ONE TO REPAIR IT.

THE ABSTRACTION IN COMPUTER LANGUAGES IS SIMILAR. WE WRITE SEPARATE CLASSES AND CREATE OBJECTS OF THESE CLASSES AND IT IS ENOUGH FOR THESE OBJECTS TO MANIPULATE THE FUNCTIONS (OR METHODS IN JAVA) WITHIN THE CLASS.

CODE OUTSIDE THE CLASS NEED NOT KNOW THE DETAILS. IT CAN SIMPLY USE AN OBJECT OF THAT CLASS IF IT NEEDS TO MANIPULATE ANOTHER CLASS. THIS IS CALLED AS ENCAPSULATION.

THE OTHER 2 CONCEPTS THROUGH WHICH WE ACHIEVE THIS ABSTRACTION ARE POLYMORPHISM AND INHERITANCE.THESE THREE WORK HAND IN HAND.

AND NOW THE FORMAL DEFINITION:

THE PROCESS ORIENTED MODEL IS THOUGHT OF AS "CODE ACTING ON DATA" WHILE THE OBJECT ORIENTED MODEL IS THOUGHT OF AS "DATA CONTROLLING ACCESS TO CODE".

TRANSFERRING THE CONTROLLING ENTITY TO DATA YIELDS SIGNIFICANT ORGANISATIONAL BENEFITS.

Answer 3

An object oriented programming system is one that uses the object oriented programming concepts. Those concepts are explained in the below question in wikianswers.
