JAVA DAY: The MasterClass for Java Developers

NICOLAI PARLOG: Java 9 Module System


Java Day is an unique event, a one day MasterClass for Java Developers, where Team Leaders, Engineering Directors and Project Managers have a great learning experience!

This time you’ll meet Nicolai Parlog, Developer, blogger, author and trainer, based in Germany. He’s put a lot of time and effort into Java 9, so scroll down to see the details. The days to study the Java 9 Module System from a distance, just by reading about it, are over – time to get your hands dirty!

This full-day workshop…

Background Image

Starts with the basics



• why is there even a module system and what does it solve?
• what’s a module and how is one defined?
• what do readability and accessibility mean and why are these terms

Teaches you refined techniques beyond the basics

• how to model optional and transitive dependencies
• how to use services to decouple modules
• how to make sure reflection is working
• how to create runtime images for or even with your application

Makes sure you can migrate your code base


• build tool support
• compatibility challenges of running on Java 9
• preparatory dependency analysis
• stepwise modularization of an existing application

Every step of the way is a short introduction of the topic, followed by solving exercises in a small demo project. Taking it from there to a real-life application is no easy task – but now you have the tools to tackle it!
