Telusko Hindi :
Encapsulation is one of the four fundamental OOP concepts.

Encapsulation is the technique of making the fields in a class private and providing access to the fields via public methods.

If a field is declared private, it cannot be accessed by anyone outside the class, thereby hiding the fields within the class.

encapsulation in Java is a mechanism of wrapping the data (variables ) and code acting on the data (methods ) together as a single unit .

[mohankiran]

can you please make a vedio about shortcuts using in net beans???

[bittooaggarwal]

sir one doubt, when the methods are public and we can access them and using methods we are accessing the variables so how does Encapsulation provide security?

[bhargavikommineni]

to avoid accessing variable values, we are making it as private. but still we are able to make/get changes with set and get methods. how come this encapsulation improve privacy!!??

[vishalkhulape]

hi ....what is the significance of using public method to access private methods I can access set n get private data members....

[MisterDibitybopty]

So why make the variables private? What benefit do you get?

[mankit]

What was the new (this..empID) command in set name???

[RaviTejaAnonymous]

how this is used and what is is the use of this here

[ulysses_grant]

Great... so, as a completely beginner in OO, I'd like to confirm: The encapsulation is done when you put "private" before the class class Emp attributes? (First day studying OOP, please, be nice everyone. Lol!)

[rsridhar]

what is purpose of creating getter method here? instead of getter method we can include the following line in setI method itself S.o.p(id); explain it please sit

[muralimohanmajjiga]

What is wrong if we directly assign value to data members directly and what benefit we get if we define data members as a private.
