In this article, I introduce the Java 9 Platform Module System (JPMS), the most important new software engineering technology in Java since its inception. Modularity—the result of Project Jigsaw —helps developers at all levels be more productive as they build, maintain, and evolve software systems, especially large systems.

Jan 2, 2024 · Java 9 has one of the major changes in its features which is the Java module System. The main aim of the system is to collect Java packages and code to be collected into a single unit called a Module.

Jun 11, 2024 · Java 9 introduces a new level of abstraction above packages, formally known as the Java Platform Module System (JPMS), or “Modules” for short. In this tutorial, we’ll go through the new system and discuss its various aspects.

Before we come to these benefits, we will explore how to define a module and its properties, how to turn it into a deliverable JAR, and how the module system handles them.

The Java Platform Module System [1] specifies a distribution format for collections of Java code and associated resources. It also specifies a repository for storing these collections, or modules , and identifies how they can be discovered, loaded and checked for integrity.

Mar 17, 2025 · Java Module System is a major change in Java 9 version. Java added this feature to collect Java packages and code into a single unit called module. In earlier versions of Java, there was no concept of module to create modular Java applications, that why size of application increased and difficult to move around.

Nov 27, 2024 · The Java module system is a game-changer for building scalable, maintainable, and secure applications. By enforcing modularity and encapsulation, JPMS makes it easier to manage complex projects and avoid dependency issues.

Java Module System - Learn about the Java Module System, its features, and how it enhances modular programming in Java applications.

Oct 2, 2023 · At its core, the Java Module System is a set of specifications and practices that enable developers to create modules within their Java applications. A module, in this context, is a self-contained unit of code that encapsulates a specific …

Java 9 introduces a new module system that makes modularization easier and more accessible. It builds on top of abstractions Java already has for modular development. In a sense, it promotes existing best practices on large-scale Java development to be part of the Java language.
