How encapsulation and abstraction are interrelated?

Answer 1

Encapsulation wraps up data and functions under a single unit and ensures that only essential features get represented without representing the background details which is nothing but abstraction. Therefore, encapsulation is a way of implementing abstraction

Answer 2

Encapsulation is hiding the details of the implementation of an object so that there are no dependancies on the particular implementation.

Abstraction is removing some distinctions between objects, so as to showing their commonalities

Encapsulation is wraping data into single unit (eg. class)

Abstraction is hiding unessential parts and showing only essential data.

(eg. student class- name, age are essential parts while height, weight are not essential, so hiding information of height and weight)

Answer 3

Abstraction is the process of generalizing the definition of an object, and in so doing making a concise, if generalized, interface implementation definition. An abstract class is a partially implemented class that must be inherited and its implementation completed before it can be instantiated. The abstract class when referenced externally infers a degree of implementation but might not infer its implementation detail. Encapsulation is the process of implementing the abstract class.

Answer 4

They are related only insofar as they are both key concepts of object-oriented programming (polymorphism and inheritance being the other two).

Encapsulation relates to the way in which an object is a self-contained entity combining data and the methods that operate upon that data. All the information required to use the object is contained within the object itself, hence the object is encapsulated, in much the same way that an egg encapsulates all the information required to produce a chick. Note that the word encapsulation derives from the word capsule, which is an apt description for an egg.

Abstraction relates to the way in which it is not necessary to know how an object is physically implemented in order to use it. This makes it possible to alter the specific implementation within the object without affecting the consumers of that object, provided the abstract interface remains exactly the same. This limits the scope of those changes to the object code itself, thus reducing maintenance. In other words, the interface itself provides a layer of abstraction between the consumer and the information contained within the object. Note that although abstraction is also known as data hiding or information hiding, there is no such feature in C++, nor indeed any object-oriented language. You can certainly limit exposure to certain features of an object by using the private or protected access keywords, but this only limits accessibility to those features, it does not physically hide anything. Think of private data as simply being contained in a cage rather than in a locked box; it is still clearly visible, but access to it is limited to just those members that have the key.

Answer 5

both are object oriented concepts.encapsulation is a way in which data and code are binded together and data used within the program in kept safe from outside manipulation by making the instance variable private(access modifier) and providing the get method to only access the data(instance variable) so your original data cannot be changed.

abstraction means only showing the necessary part of the program and hiding the details of the program.

Answer 6

They are both two totally different concepts. Encapsulation is about hiding implementation details whereas Inheritance is about re-using code.
