Meetup 145: Java 21™ What's new and noteworthy? [Eng]

Christmas time is a weird time of the year. Some say that they saw Yeti, others that their manager showed some human feelings, and others that JUG went crazy, and the next meeting will be about - Java! Impossible!
Yet, surprise, surprise, this time around we do a really deep dive into Java 21.
Our guide on the journey will be a man who knows about Java more than most of the Java architects - Piotr Przybył

Happy winter season y'all!

Abstract:
Hey, there are two major Java versions released every year! We don’t have to wait 3 years or so for new features anymore. Isn’t that cool? 😉
Java was supposed “to be slow”. However, Java turns out to evolve so fast, that next releases aren’t just version bumps, but might significantly change the rules of the game. That’s a good reason to check out what’s new in Java.
To name a few changes:
Virtual Threads, Pattern Matching for switch, Record Patterns, Structured Concurrency, String Templates, what’s gone and what will be gone, and other stuff.
If you find them interesting, let’s dive deep together into new interesting stuff.
