What is encapsulation and abstraction?

Question

What I know about encapsulation is that it is the interaction between a user and a mobile phone.

There is no need for the user to know the internal working of the mobile phone to operate, so this is called abstraction. But then how encapsulation makes its place here in this example?

Answer 1

With Encapsulation, we can achieve information hiding. For example, you don't "need to know the internal working of the mobile phone to operate" with it. You have an interface to use the device behavior without knowing implementation details.

Abstraction, on the other hand, is the capability to use the same interface for different objects. There can be a case where different implementations of the same interface can exist. Details are hidden by encapsulation.
