Sailing modern Java
Another (half a) year has passed, another major Java™ version has been released.
Java was supposed "to be slow". However, Java turns out to evolve so fast, that next releases aren't just version bumps, but might significantly change the rules of the game. That's a good reason to check out what's new in Java.
We're going to cover some features of recent Java versions:
* Pattern matching with instanceof A.K.A. Smart casting
* Sealed classes, new dimension of types extensibility (for inheritance)
* Warnings from Jigsaw (--illegal-access strikes back!)
* And Valhalla (for value-based classes abuse)
* New GCs
* and mode
Important: in this talk we're not going to cover records. For records please attent "Java records for the Intrigued" talk.
