Java After Eleven

A live-coding talk during which I update a Java 11 code base to Java 17, making good use of new language features, additional and improved APIs, and JVM capabilities

Most projects that updated past Java 8 decided to stick to the LTS release 11. The new cadence created the illusion of not much happening after that, but nothing could be further from the truth - with new language features like switch expressions, text blocks, records, pattern matching, and sealed classes, Java is moving faster than ever.

In this talk, we'll take a simple Java 11 code base, update it to 19, and refactor it to use the new language features and APIs. You'll be surprised how much the code changes!


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.
