Pattern Matching is finding its way into Java, one step at a time, along three paths:
- support for patterns
- starting with type patterns (in Java 16)
- next are deconstruction patterns (candidate for preview in Java 18)
- improvements of
switch
- making it an expression (in Java 14)
- supporting patterns (preview in Java 17)
- sealed classes (in Java 17)
In this presentation, we'll follow these three paths to see them all come together for a happy end. We'll also discuss when (not) to use pattern matching, so you can make the right choices from day one.

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.
