About us
Hello, fellow Kotlin enthusiasts! 🚀
We're thrilled to announce the unification of various Kotlin communities into a vibrant, inclusive, and dynamic collective - the Dutch Kotlin User Group (NLKUG)! Our goal is to build a lively community with lots of interesting events where we can learn and have fun.
Joining NLKUG means you'll have access to all sorts of cool stuff. We're talking about meetups led by community members, free training days, conferences, and more. It's a great way to get better at Kotlin, share your own experiences, and meet people who love coding as much as you do.
But remember, our community thrives on collective wisdom! We encourage you to bring your unique experiences and insights to the table. Because at NLKUG, every member is both a learner and a contributor. đź’ˇ

Come and be part of our journey, and let's get better at Kotlin together! 🎉

the/experts Meetup - Breda: Hands-on Kotlin for Java Developers
Location not specified yetOn Thursday, 12 February 2026, the/experts and Urs Peter are organising the meetup: Hands-on Kotlin for Java Developers.
> Why learn Kotlin when modern Java keeps getting better?
In this meetup, you’ll get a hands-on introduction to Kotlin and discover why it is often described as “a better Java”—and, more importantly, which language design choices make that claim true.
Rather than focusing on syntax or language features alone, we’ll explore the core concepts that make Kotlin a safer, more expressive, and more productive language for JVM developers – and AI-coding assistants as well:- Null-safety & secure coding by design
- Immutability-first thinking
- Expression-oriented syntax
- Concise yet readable class, collection, and function definitions
- Functions as first-class citizens
- Powerful extension mechanisms
This session is a mix of a presentation and hands-on labs: after having received an illustrative introduction of a core feature and the underlying concept, you’ll try them out yourself in a hands-on lab. As such, you will experience how Kotlin changes the way you design and write code, and see how it compares to familiar Java patterns.
So bring your laptop along!
By the end of the meetup, you’ll have a clear, practical understanding of Kotlin’s foundational ideas and enough firsthand experience to decide for yourself whether Kotlin deserves a place in your daily JVM toolbox.
