Study Notes

Object Oriented Programming (OOP) Concepts

A class in OOP is a blueprint or a template that defines the properties and behaviors of an object.
Encapsulation is the concept that involves hiding internal details and exposing only high-level public methods for accessing an object, which helps to protect the data from external interference.

Inheritance

Inheritance is the concept where child classes inherit data and behavior from a parent class, allowing for code reuse and a more hierarchical organization of code.

Polymorphism

Polymorphism refers to the ability of an object to take on multiple forms, which allows for more flexibility and generic coding.

Objects

An object in OOP is an instance of a class, which represents a real-world entity or concept, and has its own set of attributes (data) and methods (functions).

Abstraction

Abstraction is the concept of showing only the necessary information to the outside world while hiding the internal details, which helps to simplify complex systems.

Advantages of OOP

The main advantage of using OOP in developing a program is that it allows for more modular, reusable, and maintainable code.
