What is the difference between abstraction and encapsulation?

Abstraction:
Abstraction lets you focus on what the object does instead of how it does it

Encapsulation:
Encapsulation means hiding the internal details or mechanics of how an object does something.

Encapsulation is wraping data into single unit.
