RotterdamJUG (Java User Group)

For this special meetup our co-host is Portbase, the executive organisation of the Port of Rotterdam Authority and the Port of Amsterdam for digitally connecting the port community. At Portbase, the smartest port communities are built. Java is the main language used inside Portbase.

And for the second year we have a Pre-Devoxx evening! Gerrit Grunwald and Bouke Nijhuis are 2 frequent speakers which are selected to present on the Devoxx conference in October.
Gerrit will talk about "Trash Talk - Exploring the JVM memory management" and after a short break Bouke will take us in the world of "TDD & AI - a Perfect pairing?"

And we'll finish with some networking and drinks.

17:30: Doors are open, food and drinks, welcome!🍕🥤👋🏼
18:30: Trash Talk - Exploring the JVM memory management by Gerrit Grunwald from Germany🇩🇪

In the realm of Java programming, understanding memory management and garbage collection mechanisms cannot only be helpful for optimizing performance and resource utilization but also in general will help you to use the right garbage collector for your application. This session will be about memory allocation, object lifecycle, and garbage collection strategies within the Java Virtual Machine (JVM). Attendees will gain insights into memory allocation strategies, object retention policies, and various garbage collection algorithms like generational and concurrent collection. So when you are interested in getting more knowledge about which garbage collector to use best for your application or about memory management in the JVM, this session is for you.

19:30: TDD & AI - a Perfect pairing? by Bouke Nijhuis

In this talk we will dive into the question whether generative AI can generate working code when we only provide test cases. So we take the main principle from TDD: we write the tests up front. Then we use a generative AI to create the code. If you wrote the tests correctly and they all pass, you should have a working prototype. Even better, if the tests pass and you trust the tests, the code is production ready!

With some live coding, we will explore this idea together. Furthermore we will take a look at the implications of this paradigm shift. After attending you should be able to apply this technique to your own project.

20:30: Networking with some drinks🥤🧀
21:00: Time to go home🚉
