Modern Java in Action

Let's write a GitHub Crawler and let's throw in everything Java (22) has to offer

So you learned about all these new Java features but want to see how they come together? Then let's write a GitHub Crawler and let's throw in everything Java (22) has to offer:

  • virtual threads and structured concurrency
  • pattern matching and data-oriented programming
  • type inference, records, and sealed types
  • text blocks and template strings
  • a modern HTTP client and improved collections
  • modules and OS-specific binaries

The end result will look very different from just a few years ago, let alone 10. This is not your parents' Java!


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.

Upcoming Presentations

In the coming months, I'll present this talk at GOTO Amsterdam and J-Spring. 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.)

Past Presentations

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.
