Object-Oriented Programming (OOP)is widely used in software development and has many benefits such as code reusability, flexibility, and maintainability.

OOP is a programming paradigm that organizes code and data into reusable objects. It is based on the concept of “objects,” which represent real-world entities or abstract concepts and have both data (attributes) and behavior (methods) associated with them. The key principles of OOP include encapsulation, inheritance, and polymorphism.

What is Object-Oriented Programming?

Here are the fundamental concepts of Object-Oriented Programming:

  1. Objects: Objects are instances of classes that encapsulate data and behavior. They can interact with each other through method calls and can have their own unique state.
  2. Classes: Classes are blueprints or templates for creating objects. They define the structure, behavior, and properties that objects of that class will possess.
  3. Encapsulation: Encapsulation refers to the bundling of data and methods within a class, hiding the internal implementation details from outside access. It provides data protection and allows for better control over access to the object’s properties and methods.
  4. Inheritance: Inheritance allows classes to inherit the properties and methods of other classes, forming a hierarchical…
