what is encapsulation?

Answer 1

encapsulation:wraping of data & its functions into single unit

Answer 2

It is the idea that the implementation details of a class and its function should be kept to function names and requested arguments only.

You should never give direct access to a classes internal state or fields, only public access points (getter and setter functions).
In short, I should only know the required input and exspectd output, not how that output is achieved.

Answer 3

Enclosing something inside of something, not revealing the internals to the outside. Making a "black box".

Answer 4

wrapping of data into one single unit
