The Java Platform Module System (JPMS), introduced in Java 9, enhances the Java programming language by allowing developers to modularize their applications. This system enables better organization of code into distinct modules, which can encapsulate their internal implementation while exposing only necessary parts through public interfaces. This modular approach improves maintainability and reduces the risk of conflicts between different parts of a program. With JPMS, developers can define module dependencies explicitly, making it easier to manage libraries and frameworks. It also supports better performance and security by allowing the Java Virtual Machine (JVM) to optimize the loading of modules. Overall, JPMS aims to simplify large-scale application development in the Java ecosystem.
