Object-Oriented Programming (OOP) in Java is a programming paradigm that organizes software design around objects rather than functions or logic. It models real-world entities using classes and objects, making code more modular, reusable, and easier to maintain.

Core Concepts of OOP in Java:

1. Class:
   A blueprint for creating objects. It defines properties (fields) and behaviors (methods).

2. Object:
   An instance of a class. It holds real values for the fields defined in the class.

3. Encapsulation:
   Bundling data (fields) and methods into a single unit (class), and restricting direct access to some components using access modifiers (private, public).

4. Inheritance:
   Allows one class to inherit fields and methods from another class using extends. Promotes code reuse.

5. Polymorphism:
   Enables one interface to be used for different underlying data types. Can be method overriding (runtime) or overloading (compile time).

6. Abstraction:
   Hides internal details and shows only essential features. Achieved using abstract classes or interfaces.

Summary:

Java's OOP principles help developers build flexible, modular, and scalable software by modeling real-world systems through classes and objects.
