Understanding Java OOP Concepts with Code Implementation Object-Oriented Programming (OOP) is a programming paradigm that revolves around the concept of “objects”. Java is one of the most popular programming languages that fully supports OOP. If you're learning Java, mastering its OOP principles is essential for writing robust, reusable, and maintainable code. In this article, we'll explore the four main OOP concepts in Java : Encapsulation Inheritance Polymorphism Abstraction Each concept will be explained in detail with practical code examples. 🔹 1.
