pattern matching
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:
Records, where and how to use them, apart from DTO/VO Pattern matching with instanceof A.
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?

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.
In the chase for non-trivial examples to illustrate possible usage of JEP 305, some people might have gone too far, I guess. In particular into the more challenging area of the equals() method, present in all Java objects.
Java 14 has a lot of new features. One of them (as preview feature) is pattern matching with instanceof. Some people programming in languages supporting the functional paradigm to some extent, e.g. Scala, Kotlin (not to mention Haskell) jumped high, full of joy ‘Yay, we gonna have match or when, extracting data, guards, deconstructors in companion objects and more!’
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.
