In this lecture of the Java Full Course, we explore two of the most important Object Oriented Programming (OOP) concepts in Java : Encapsulation and Inheritance.

You will learn how Encapsulation helps in data hiding and protecting object state, and how Inheritance allows classes to reuse code and build hierarchical relationships between objects.

Through practical coding examples, we understand how these concepts are used in real Java applications and why they are fundamental for writing clean, modular, and maintainable code.

This lecture is part of the Java Full Course playlist designed for beginners and intermediate developers who want to build a strong foundation in Java and Object Oriented Programming.
