Java Records for the Intrigued
Conference
Java 14 brought Records as one of the preview features, and in Java 16 they're a standard feature. For many it was reasonable to say "no more JavaBeans code generation" or "Lombok is dead". Is that the case? What one can do with records and what can't? What about reflection and serializations? You will learn in this session.
Scheduled on Wednesday from 13:30 to 14:20 in Room 2
Sailing modern Java
Conference 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.
Scheduled on Wednesday from 16:00 to 16:50 in Room 2
