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.
