What is the Java Platform Module System

The Java Platform Module System (JPMS) is a significant feature introduced in Java 9 that allows developers to modularize their applications. It enables the organization of code into distinct modules, improving maintainability, scalability, and security. JPMS helps in controlling visibility, managing dependencies, and providing a clearer structure for applications.

With JPMS, developers can define module boundaries, specify which packages are accessible, and control module dependencies, thus enabling better encapsulation of functionality and reducing the chances of conflicts in larger applications.

Example of a Simple Module Definition

        module com.example.myapp {
            requires java.base; // This module requires the base module.
            exports com.example.myapp.service; // Export a package for other modules.
        }
