Answer / cherry
abstraction means hiding the implementation part of a
particular process.Like we are calling createStatement()
method on Connection object to get the Statement object.It
is also abstraction because that method implementation is
done by jdbc engine developer.

Answer / gaurav (accenture)
Just to tell you guys that abstraction and encapsulation are two different concepts of oops. thats why they've use two terminologies. Common Sense. Right.!
The meaning of abstraction is just the same as it is in English but applying it in coding world. Simply we can say as “what” the method or a module does not “how” it does it. The word abstraction is to distill a complicated system down to its most fundamental parts and describe these parts in a simple, precise language.
Let’s compare Java and C++. We have a good example of abstraction. In C++, you have to deal with pointers and references a lot. You have to deal a lot of garbage collection. In essence, you have to work on a low level. (C and C++ in turn abstracted a lot of even lower level machine code.) In Java, those things are abstracted away. You just assume they exist. In essence, abstraction means that you are working on a higher level. You don’t care how pointers work in Java, you just assume that they work. You don’t have to concentrate on the lower level stuff, you work on higher level.
I hope it covers everything.

Answer / satishkumar vishwakarma
Abstraction means showing only relevent data. means that it
shows only that part of code which is necessory for other
class rather than showing all information. Encapsulation
also does same thing. the whole funda of Abstration and
Encapsulation is Class and Access Specifiers.
