Abstractions
Example:
I have class Animal and i am making a sub class of the class Animal called Tiger.
Then i will say that its colour is yellow and running is very fast.
Also i can make the class Hippo but it's colour is black and running is very slow.
This is an example of Abstraction.
Encapsulation:
Example:
Just think of a capsule that the doctor gives us.
We just have to take the capsule to get better. We don't have to worry about what medicine is inside the capsule or how it will work on our body.
What it means that we give access to our class via proper methods and properties. The user does not have to worry how this methods and properties work.
