what are the oops concept in java explain with real time
examples
Answer Posted / devendra.m
OOPS Concepts are mainly 4
1.Abstraction
2.Encapsulation
3.Inheritance
4.Polymorphisam
Abstraction:-Hidding non-essential features and showing the
essential features
(or)
Hidding unnecessary data from the users details,is called
abstraction.
Real Time example:TV Remote Button
in that number format and power buttons and other buttons
there.just we are seeing the butttons,we don't see the
button circuits.i.e buttons circutes and wirings all are
hidden.so i think its good example.
Encapsulation:
Writing Operations and methods stored in a single
class.This is Called Encapsulation
Real Time Example:Medical Capsuals
i.e one drug is stored in buttom layer and another drug is
stored in Upper layer these two layers are combined in
single capsual.
Inheritance:
The New Class is Existing from Old Class,i.e SubClass is
Existing from Super Class.
Real Time Example:
Father and Son Relationship
Polymorphisam:
Sinle Form behaving diffreantly in diffreant
Situations.
Example:-
Person
Person in Home act is husband/son,
in Office acts Employer.
in Public Good Cityzen.
I think these all are real time experianceany.is there any

Thanks all
