A Beginner's Guide to Java Module Folder Structure

Java modules organize code into a clear hierarchy: a module contains packages, which in turn contain classes. The key file is module-info.java, which defines the module's dependencies and exported packages. This structure helps developers build scalable, maintainable applications by enforcing strong encapsulation. Start with a top-level directory for your module, then add packages for related classes, and don't forget the module-info.java at the root.
