Rohan I think there are many conversations, posts, blogs & articles written on Abstraction & Encapsulation difference. But very few places people cleared the things.

Abstraction : - Showing only abstract model or hiding implementation complexity to user. No need to show complete implementation. Like ABSTRACT class/method and INTERFACE.

Encapsulation : - It is keeping data & function in a container called class so that we can maintain the accessibility of class/method/property through different access modifiers. Like using PUBLIC/PRIVATE/PROTECTED/INTERNAL.

If this is helpful for you then please accept my Answer.

Hello Rohan

Abstraction is "the process of identifying common patterns that have systematic variations; an abstraction represents the common pattern and provides a means for specifying which variation to use" (Richard Gabriel).Abstraction means to show only the necessary details to the client of the object
Encapsulation is a strategy used as part of abstraction. Encapsulation refers to the state of objects - objects encapsulate their state and hide it from the outside; outside users of the class interact with it through its methods, but cannot access the classes state directly. So the class abstracts away the implementation details related to its state.

They are different concepts.

Abstraction is the process of refining away all the unneeded/unimportant attributes of an object and keep only the characteristics best suitable for your domain.

Abstraction allows us to represent complex real world in simplest manner. It is process of identifying the relevant qualities and behaviors an object should possess, in other word represent the necessary feature without representing the back ground details.
Encapsulation It is a process of hiding all the internal details of an object from the outside real world. The word Encapsulation, like Enclosing into the capsule. It restrict client from seeing its internal view where behavior of the abstraction is implemented

Think of a cellphone.
Abstraction is the keypad key wherein when you press 5 or 7 the corresponding circuit/chips will triggers something inside the phone. In other words, instead of tapping the chips directly, cellphone uses keypad to interact with the internals.

Encapsulation is the chips or circuits inside your phone. These are hidden from the users who uses the phone and kept internally.

Hi Rohan Gupta,

Go through below link-

Abstraction focuses on the outside view of an object (i.e. the interface)Encapsulation (information hiding) prevents clients from seeing its inside view, where the behavior of the abstraction is implemented.
