Yesterday in an Interview I was asked
How Does Encapsulation works internally ?
I was really confused because as per me Encapsulation is simply
"The state of a class should only be accessed through its public interface."
but when it comes to internal working I ran out of words.So if anyone can explain that it would be so helpful.

I agree with commenters that asking for clarifications is a good idea - good questions can be even better than good answers, and allow you to ensure that you are actually answering what they think that they are asking.
