Study Notes

The Importance of Object-Orived Programming in Java

Object-oriented programming (OOP) is a programming paradigm that revolves around the concept of objects. These objects represent real-world entities or abstract concepts, consisting of attributes and methods. Java is a widely used programming language that fully embraces the principles of OOP, offering a rich set of features like classes, objects, inheritance, and polymorphism. Java's integration of OOP has made it an excellent choice for developers creating efficient, maintainable, and scalable software solutions.

In Java, OOP is built upon four fundamental pillars: Abstraction, Encapsulation, Inheritance, and Polymorphism. Let's explore each of these pillars:

Abstraction

Abstraction allows us to focus on what an object can do rather than how it does it. It involves creating abstract classes and interfaces, which define common behaviors and characteristics without specifying the implementation. In Java, abstract classes cannot be instantiated, and their methods need to be implemented by derived classes. For example, in a car simulation, we could create an abstract 'Vehicle' class, defining common attributes and behaviors for all vehicles, like moving and stopping.

Encapsulation

Encapsulation refers to the bundling of data (attrib
