Most projects that updated stick to the long-term support versions 11 or 17. The new cadence created the illusion of not much happening in between and after that, but nothing could be further from the truth - with new features like pattern matching, virtual threads, and structured concurrency, Java is moving faster than ever.
In this talk, we'll take a simple Java 17 code base, update it to 21, and refactor it to use the new Java capabilities.
Here's the current version of the slides.
I also embedded them below. If they're focussed, you can navigate with arrow keys or swipes (they're two-dimensional, with chapters on the horizontal axis and chapter content layed out vertically). Use Page Up/Down for linearized order and ? for more shortcuts.
Here's a good recording of the talk. I hope you'll like it.
In the coming months, I'll present this talk at GOTO Amsterdam. If you're there as well, I'd love to meet you - I'm always up for a chat. 😁 Just flag me down when you see me. (This includes chat rooms.)
I gave this talk a few times before. See below for links to slides (as they were at that very event), videos, and other information.
