Abstraction VS Information Hi

Answer 1

Abstraction is like using a computer.

You have absolutely no idea what's going on with it beyond what you see with the GUI (graphical user interface) and external hardware (e.g. screen). All those pretty colors and such. You're only presented the details relevant to you as a generic consumer.

Encapsulation is the actual act of hiding the irrelevant details.

You use your computer, but you don't see what its CPU (central processing unit) looks like (unless you try to break into it). It's hidden (or encapsulated) behind all that chrome and plastic.

In the context of OOP (object-oriented programming) languages, you usually have this kind of setup:

CLASS {
  METHOD { 
    *the actual code*
  }
}

An example of "encapsulation" would be having a METHOD that the regular user can't see (private). "Abstraction" is the regular user using the METHOD that they can (public) in order to use the private one.
