5) abstraction and encapsulation difference

Question

Accepted Answer

Abstraction focuses on hiding unnecessary details while encapsulation focuses on protecting data.

Abstraction is about showing only the necessary details to the user while hiding the implementation details.
Encapsulation is about wrapping data and methods together to protect data from outside interference.
Abstraction is achieved through abstract classes and interfaces while encapsulation is achieved through access modifiers like private, public, and protected.
Example of abstraction: A car dashboard shows only necessary information like speed, fuel level, and temperature while hiding the internal workings of the car.
Example of encapsulation: A bank account class that has private variables for account number and balance and public methods for deposit and withdrawal.
