The Three Best Articles to Get You Started

Hello John Doe,

Over 120 articles are waiting for you on the HappyCoders blog. Where should you start? Here are three that will give you the most:

1. Java 27 Features
All the new features of the current Java version, with examples – keeping you at a level many teams won't reach for years.

2. How to Change Java Versions in Windows
The most-visited article on the site: install multiple JDKs side by side and switch with a single command.

3. Virtual Threads in Java – Deep Dive
How virtual threads work under the hood, when they actually make your application faster – and when they don't.

That's it from me for now. From now on, you'll receive the regular HappyCoders newsletter once a month.

Happy Coding!
Sven

P.S.: One last question, a single click is all it takes: Which Java version are you working with right now?

Java 8 or older · Java 11 · Java 17 · Java 21 · Java 25 or newer · Changes all the time / no fixed version
