Java Modules Explained: Packages, Encapsulation & Dependencies | Java 21
Confused by Java modules? In this video, we break down exactly how the Java Module System groups packages to keep your code clean, organised, and maintainable.
Here's what we cover:
✅ How modules group packages and why it matters for code organisation
✅ Encapsulation in plain English — hiding what doesn't need to be shared
✅ Why explicit dependency declarations aren't optional in modular Java apps
Whether you're moving from classpath-based Java to the module system, or just trying to understand why module-info.java exists — this video has you covered.
