What is Object-oriented programming (OOP)?

Object-oriented programming is the process of integrating variables (properties) and functions (methods) into a single object. These products are organized into classes that may be mixed and matched. OOP allows you to think about the objects in a program’s code as well as the various actions that go along with them.

What are the principles of Object-oriented programming (OOP)?

Encapsulation, Abstraction, Inheritance, and Polymorphism are the four basic concepts of object-oriented programming. Although these concepts appear to be extremely complicated, understanding the broad framework of how they work is beneficial. The four basic hypotheses are as follows:

1. Inheritance: child classes inherit data and behaviors from parent class
2. Encapsulation: containing information in an object, exposing only selected information
3. Abstraction: only exposing high level public methods for accessing an object
4. Polymorphism: many methods can do the same task
