Text Blocks

In the dark ages, we had to wait for 3-4 years to see the new Java version with some new features. Now there are two major releases every year! Can we benefit from the new features before the next LTS release?

We don’t have to wait 3 years or so for new features any more. Isn’t that cool? 😉 So… you’d like to check what has happened since Java 11? Record types? Switch expressions? Pattern matching? No more NPE? String blocks? New functions in APIs? What are the Shenandoah and ZGC about? AppCDS to speed up spin-off?

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 game rules. That’s a good reason for another deep dive in Java. We’re going to cover:

• Production ready GCs: ZGC and Shenandoah, if you don’t like ice ages
• Text blocks, which make Strings easy to declare also for non-liners
• Pattern matching with instanceof A.K.A. Smart casting
• Records, where and how to use them, apart from DTO/VO
• Sealed classes, new dimension of types visibility (for inheritance)
• Hidden classes, which are so hidden, that they can’t even use themselves
• Foreign memory access, for some off-the-heap data
• Helpful NPE messages, which make chasing nulls easier than ever

And of course removed, deprecated and tuned stuff (bye bye Nashorn). All visualised in actual code, not just slides.

Hey, there are two major Java versions released every year! We don’t have to wait 3 years or so for new features any more. Isn’t that cool? ;-)

So… would you like to check out what has happened in Java 14?
Switch expressions available to public?
No more NPEs?
Record types?
Pattern matching?
Text blocks?
If you find them interesting, let’s dive deep together into new interesting stuff.

This talk has been presented at Wrocław JUG and Warszawa JUG.
