What we’re about
This JUG aims to build a community around everything to related with Java and JVM like new language features, Spring, Kotlin, Cloud, Containers, etc...
We are going to organize meetups, if you have something interesting to share with the community, please feel free to open a discussion or send a private message to us in order the schedule a meetup.
We work together with Coimbra JUG (https://www.meetup.com/Coimbra-JUG/) in order to get the most to everybody.

Title: DuckDB with Java: Embedded SQL Analytics on Files without a cluster
Speaker: Andrey Novov, Senior Java Developer @ BNP Paribas CIB Portugal
Summary:
Context: Run fast, reliable SQL analytics diretcly on files (CSV, parquet/s3) from Java, without inroducing a separate anylitucs cluster. How duckdb plugs into Java, Design patters for several use cases:, practical outcomes.
Why now? File-backed datasets keep growing; teams in the projects need ad-hoc exploration, reconciliations, and data quality checks that repeatable and easy to ship.
Consumers: Internal APIs, reconciliation jobs, data QA checks so not only analytics but also developers.

Title:
JEP 512, JBang, Notebooks, GraalPy, and Raspberry Pi for Interactive Learning
Speaker: Igor Souza, Software Engineer @ Teckro
Summary:
Is Java too heavy for learning programming? Not anymore. With JEP 512, JBang, and Notebooks, setup pain is gone. Bringing joy back to simple, interactive Java programs.
In this session, I’ll walk through each topic from the title, one by one, showing how they work together to make Java a fun, hands-on learning language again:
* JEP 512 and how it simplifies the startup experience.
* JBang turning Java into a CLI-friendly scripting language for small experiments.
* Jupyter Notebooks making Java interactive for education and documentation.
* GraalPy bridging Java and Python ecosystems.
* And finally, using Raspberry Pi as a creative lab for Java-based electronics and IoT experiments.
You’ll see how educators, hobbyists, and developers can use these tools to write, test, and teach Java just like Python notebooks — including live demos of Java running interactively, invoking graphics, and controlling hardware on a Raspberry Pi.
Perfect for educators, students, and developers curious about modern Java tooling and how it’s transforming how we learn and teach programming.
