Introduction to Object-Oriented Programming using Java

A programming paradigm that organizes software design around objects and classes to improve modularity and maintainability.

The bundling of data (variables) and methods that operate on that data within a class, restricting direct access to some components.

A mechanism where one class can inherit properties and methods from another class, enabling code reuse.

The ability of different classes to be treated as instances of the same class through method overriding and overloading.

The concept of hiding complex implementation details and exposing only the necessary features of an object or class.
