This article explains why Java modularization was introduced, outlines the problems with the pre‑Java 9 classpath, introduces the Java Platform Module System (JPMS) and its core file module-info.java, and provides detailed guidance on concepts, syntax, best practices, real‑world examples, IDE setup, and common pitfalls.
This article explains the common pain points of Java package management—naming conflicts, circular dependencies, and version chaos—and shows how modular design using JPMS, strict Maven rules, and tooling can dramatically reduce conflicts, build time, and improve code maintainability.
This guide explains the Java 11 migration process, covering the new JDK release schedule, LTS support, OpenJDK and Amazon Corretto adoption, required tool upgrades, JPMS module changes, class‑loader differences, obsolete JVM options, and common framework compatibility problems.
This article provides a comprehensive overview of Java 9’s major new features—including the JPMS (Jigsaw) module system, updated APIs, security improvements, the new HTTP/2 client, AOT compilation, and the time‑driven release model—illustrated with code examples and practical guidance for developers.
