Abstraction:-
Hiding internal implementation and just highlighting the set of services what we are offering, is known as "Abstraction".
example:-
Through Bank ATM GUI screen bank people are highlighting the set of services what they are offering without highlighting internal implementation.
The main advantage of Abstraction are:-
- We can achieve security because we are not highlighting our internal information or implementation.
- Without affecting outside person we can able perform any type of change in our internal system and enhancement will become easy.
- It improves maintainability of the application.
- By using interface and abstract classes we can implement Abstraction.
