I’ve been working with Java for 30 years as a developer, CTO, trainer, author, and speaker – and have helped companies modernize complex Java systems and develop their teams sustainably.
With HappyCoders.eu, I’ve built one of the most widely read Java blogs in the German-speaking world and regularly speak at conferences and user groups.
The PDF covers the most important updates of all 17 Java versions from Java 10 to Java 26 on 25 pages – and is updated with every Java release.
My blog covers a wide range of Java, software architecture, and performance topics – from foundational concepts to advanced patterns.
If you want to dive deeper, take a look at my trainings: hands-on, easy to follow, and directly applicable to your day-to-day project work. Instead of pure theory, I focus on principles that help you write code that’s better, more maintainable, and more performant in the long run.
