Java 23 - Better Language, Better APIs, Better Runtime

Java 21 was an explosive release, but 22 and 23 are no slouches either: unnamed patterns, stream gatherers, multi-source-file launcher, Markdown in JavaDoc plus many new and improved features in preview

Java 21 was an explosive release, but 22 and 23 are no slouches either:

  • from unnamed patterns to module imports
  • from the foreign-function and memory API to stream gatherers and the class-file API
  • from a simpler main to launching multi-source-file programs
  • from Markdown in JavaDoc to improved garbage collection

There are plenty of features in the language, API, and runtime to discuss - whether new, improved, or finalized. So let's go over them!

Slides

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.

Video

Here's a good recording of the talk. I hope you'll like it.
