Answer:

Encapsulation is one of the fundamental concepts in object-oriented programming (OOP). It describes the idea of bundling data and methods that work on that data within one unit, e.g., a class in Java. This concept is also often used to hide the internal representation, or state, of an object from the outside.

Some information about OOP :-

The object oriented approach focuses on data rather than procedure and structures this is a method where programming is adjusted and modelled on the basis of real life entity and process .

For example in a school library system there are object like book , student and processes like book issue , book return etc .

oop approach allows the programmer to create data variable or object .

It divide the program into building blocks for all objects and then be used in data and methods around these object .

2. data abstraction
3. inheritance
4. polymorphism
