Staying up to date with Modern Java can feel overwhelming. If you don’t have any experience with Java since Java 8 (or at all), features like structured concurrency or pattern matching might sound exciting, but also scary: “How do I even get started with that?”

Fear not! In this session Marit and Piotr will explain to you the new exciting things and also show you how to use them in your IDE, so that the next day you can start having fun and profit with modern Java in your favorite tools on your own.

Who It’s For:

• Developers who haven’t worked with recent Java versions yet
• Developers coming from other languages who want to get started with modern Java

Level

Beginner to Practitioner

Artificial intelligence is everywhere right now, and one of the most frequently recommended patterns for building AI-powered applications is Retrieval-Augmented Generation (RAG).

But what does that actually mean in practice? How do you implement it? What does it require? And perhaps most importantly, do you really need it?

Key takeaways

What RAG actually is and how it works What infrastructure and data are required to implement it When RAG is useful (and when it may be unnecessary)

Who Is This For?

• Software engineers exploring AI-powered applications
• Developers experimenting with LLM integrations
• Architects evaluating when RAG makes sense

What This Session Covers

In this session, Piotr explores the practical side of Retrieval-Augmented Generation.

Instead of treating RAG as a buzzword or default architecture, the talk examines when it is useful, what it takes to implement it, and when it may not be the right solution.

Through working code examples, you’ll see how RAG systems are built and what trade-offs they introduce.

Talk style

• Code walkthrough with some editing / switching parts on and off
• Practical implementation discussion
• Real-world engineering considerations
