Day 15 | Java Package and Access modifiers Explained 🚀 | 30-Day Java Challenge
Welcome to Day 15 of my 30-Day Java Interview Challenge 🚀
Today’s topic focuses on how Java code is organized and protected:
✔ What are Packages in Java
✔ Built-in vs User-defined packages
✔ Access Modifiers in Java
✔ public, private, protected, default
✔ Scope and visibility rules
Packages help organize large Java projects, while access modifiers control who can access classes, methods, and variables.
Both concepts are very important for Java interviews and real-world development.
