#JavaNEXT

Java devs no longer need the visitor pattern! With sealed classes (final in #Java17) and pattern switches (preview in 17), #JavaNext offers a better and shorter solution to the problems the pattern addresses.

Presenting #JavaNext at #jPrime (slides: I asked "What's your newest Java version in prod?" Java 7: 1 (not the same guy as previous conferences - I asked) 8: 10% 11: 20% 17: 20% 18: 0 What about the other half? 🤷 But 40%-80% beyond 8 is very nice!

Over the last weeks, I've back-filled and updated my Java X Feature Demo, all the way up to #Java18, including a bit of vector API image manipulation for #JavaNext - check it out:

Conversation with @BrianGoetz about pattern matching in #JavaNext: * why `Map::get` should be a pattern * the linear thinking trap * null handling in pattern matches * exhaustiveness in switch statements * the rehabilitation of `switch`

Chipping away at Unsafe: JEP 371: Hidden Classes "Allow frameworks to define classes as non-discoverable implementation details of the framework, so that they cannot be linked against by other classes nor discovered through reflection." #JavaNext

Learn everything about #JavaNext in my speedrun through projects Amber, Loom, Panama, and Valhalla at #JavaLand2022 in Wintergarten. In 3 minutes, so better hurry. 😉

I had a great time yesterday at @virtualJUG talking about #JavaNext: recent and upcoming releases, OpenJDK vs Oracle JDK, licensing, going beyond #Java11 and current projects like Amber, Valhalla, and Loom. Slides: Video:

How do you name unused variables? If even just having to make that choice annoys you (it's not just me, right?), read on for how #JavaNext will fix that and make pattern matching (how's that related?!) more maintainable in the process. 🧵

Last week I gave my updated #JavaNext talk at @VoxxedZurich - in 45 minutes, you get an overview of the current state of projects Amber, Panama, Valhalla, and Loom: Here are four highlights. 👇🏾🧵

Want to peek into Java's future? Interested where Projects Amber, Loom, Panama, and Valhalla will bring #JavaNext? Find an hour over the weekend and let @mreinhold tell you about it: (Recorded at @DevoxxUK 2019.)

Big string template revamp - processors are out! 😳 "Processors were envisioned as a means to abstract the transformation of templates to their final form. However, Java already has a well established means of abstracting behavior: methods." #JavaNext

"Before we can talk about where generics are going, we first have to talk about where they are, and how they got there." writes @BrianGoetz in How we got the generics we have (Or, how I learned to stop worrying and love erasure) #JavaNext

How Java's upcoming string literals may manage indentation: #JavaNext

Interesting detail on primitive types: "As a matter of style, we suggest avoiding the legacy wrapper class names in new code, preferring the .ref types instead." I.e. `int.ref` instead of `Integer` just like we'd do with custom primitives, e.g. `Point.ref`. #JavaNext

Project Amber is making progress on pattern matching in #JavaNext. Here are three recent developments that I'm very excited about and I think you will be as well. (Caveats: these are ongoing discussions; none of this is final; speculation and strawman syntax ahead)

Sitting in the train to visit family over the weekend I'm watching the #JVMLS2019 talk on Project Loom by Alan Bateman and Rickard Bäckmann ( Wifi permitting, I will tweet my comments. 1/? #JavaNext

April will be busy: * talking about #JavaNext today at @jug_stuttgart, later at @DevoxxFR and @jugka * squeezed in two #JUnitPioneer streams * looking forward to modularizing @EclipseCollect with @TheDonRaab and @sirishapratha See you at the events or on Twitch! 😃

Wohoo, #ProjectValhalla started publishing early access builds: Will play with it on Friday. This is gonna be awesome!! #JavaNext

[NEW POST] How to use #JavaNext preview features like switch expressions and text blocks: * command line flags * Eclipse, IntelliJ, Maven, Gradle configuration * safeguards * WHY?!

#GeekOutEE just published videos of all talks. Kudos! If you have an hour to learn about how Java is evolved and which great things are coming, check out my talk #JavaNext: video: slides:
