Answer 1

The wording of your question is odd - Abstraction vs Encapsulation? It should be - someone explain abstraction and encapsulation...

Abstraction is understanding the essence of the thing.

A real world example is abstract art. The artists of this style try to capture/paint the essence of the thing that still allows it to be the thing. This brown smear of 4 lines captures the essence of what a bull is.

Encapsulation is black boxing.

A cell phone is a great example. I have no idea how the cell phone connects to a satellite, tower, or another phone. I have no idea how the damn thing understands my key presses or how it takes and sends pictures to an email address or another phone number. I have no idea about the intricate details of most of how a modern smart phone works. But, I can use it! The phones have standard interfaces (yes - both literal and software design) that allows someone who understand the basics of one to use almost all of them.

How are the two related?

Both abstraction and encapsulation are underlying foundations of object oriented thought and design. So, in our cell phone example. The notion of a smart phone is an abstraction, within which certain features and services are encapsulated. The iPhone and Galaxy are further abstractions of the higher level abstraction. Your physical iPhone or Galaxy are concrete examples of multiple layers of abstractions which contain encapsulated features and services.
