Description J-Fall 2022 is the Java Conference of the Netherlands. Where they welcome 1800+ attendees at Pathé Ede on the 3rd of November.

Expect the best (inter)national speakers including a bunch of Java Champions giving in-depth sessions, inspiring keynotes and practical hands-on workshops. But it is so much more than quality content delivered by Java gurus. The prestigious NLJUG Innovation Award will be presented to the most impressive and innovative Java project of the year. The market floor is full of companies who embrace Java and everything that it stands for. It’s a day you can’t miss out on in which you will get ahead of the curve while meeting the best community members of the world.

Hanno Embregts and Peter Wessels will give a session about: Pattern Matching: Small Enhancement or Major Feature?
At first it seemed to be just a small enhancement: the addition of "Pattern Matching for instanceof" (JEP 305) in Java 14. No more unnecessary casting after an `instanceof`, that ought to save us a few seconds a day! However, upon further investigation you'll quickly discover that pattern matching is not just an enhancement, but rather a vital puzzle piece in the grander scheme of things. Why were switch expressions added to Java, for example? To make them support pattern matching in a later release! And why did Java 14 bring us records and did Java 15 contain sealed types? Because they could work really well with pattern matching in a later release! These new concepts are the foundation upon which advanced pattern matching features will be built. So attend this session to get all caught up! You'll hear about type patterns, deconstruction patterns, nested patterns and even how pattern matching could improve serialization in the future. Live coding included, of course!

Hanno Embregts is also part of a Panel: Exploring Sustainability in Tech Without the Guilt-Trips
Most of us are all well aware of it: the current trend of climate change is not looking great. We can already feel some of its consequences and it is very likely to only become worse. As software developers we’re all about innovation though, so as long as we’re innovating not all hope is lost. So how can you use innovation to become more sustainable, both as a software developer and as a human being? There is no single answer to that question, which is why we’re hosting this talk as a panel so that you’ll be able to hear multiple opinions. Each of us has a different perspective and knows different things we can do to help make a difference, and we'd like to hear from you as well!

We’d like to emphasize that we don’t want to guilt-trip anyone. This session is intended as a source of inspiration. The sheer scope of the problem can cause even the best of us to freeze up. Hearing ideas, no matter how small, from peers will provide you and us with ideas for the next step to take. This talk could be an opportunity for you to catch a few sustainability tips that can find their way into your life without costing you any noticeable effort.

Maarten Mulders will give the session: What's Cooking in Maven?
It’s been over 10 years since Maven 3 saw the light, bringing initial multi-module support. Later releases brought a lot of improvements, bug fixes, and of course coloured output. But the Maven community hasn’t been resting on their laurels. A lot of effort has gone into the future of Maven. You may have heard about Maven 4, Maven Wrapper, or Maven Daemon. Why should you care? And how will it change the way you use Maven? I will show you by using the latest snapshot builds of Maven - time will tell if that’s a brave or a stupid idea… Join me to find out what the future of Maven has for you!
