Java Module System

Creating a reliable and secure application is much easier if you package the code into neat blocks. The module system in Java is a language standard for creating such blocks. Now you can control the interactions of various JARs and easily detect missing dependencies. Fundamental architectural changes have affected the core of Java starting from version 9. All core APIs are distributed in the form of modules, and a similar approach can be considered a good practice and recommendation for libraries, frameworks, and applications.
