Question

Difference between data abstraction and data encapsulation

Answer 1

Encapsulate hides variables or some implementation that may be changed so often in a class to prevent outsiders access it directly. They must access it via getter and setter methods.

Abstraction is used to hiding something too but in a higher degree(class, interface). Clients use an abstract class(or interface) do not care about who or which it was, they just need to know what it can do.

Data Encapsulating:-

• The data is not accessible to the outside world they can be accessed only by its method,which are wrapped within the class.
• The wrapping up of data and member function into single unit is called encapsulating.
• Data encapsulating is the most important feature of the class.
• The process of protecting data from direct access by the program is called data hiding or information.

Data Abstraction:-

• Abstraction refers the act of representing essentially feature where no background details are explained.
• Data Abstraction helps in clear separation between the abstract properties and the details of its implementation.

$example$

we need basic options for starting the computer like shutting down and knowledge to use the peripherals.

we need not know the internal functioning or the complex architecture of the system.
