Welcome to Lecture 38 of the course "Programming Concepts using Java" by Prof. Madhavan Mukund.

Video Overview
This lecture introduces Java packages, the mechanism that helps organize classes and prevent naming conflicts in large applications. We discuss how packages establish a hierarchical structure, much like file systems or reversed internet domain names, to make codebases easier to manage and maintain. You’ll learn how to create and import packages, the role of the default (package-private) visibility modifier, and the use of the protected access modifier to control visibility within class hierarchies. By the end of this lecture, you will understand how packages promote modularity, collaboration, and cleaner design in Java programs.
