#JavaNEXT

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!

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. 🧵

val html = ` <div> <p>OMG, I can't <b>believe</b> we get multi-line strings in #Java12!</p> </div>`.align(); #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

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

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.

On holiday on Crete right now, right there at the beach! 🏝️ But it wouldn't be a real journey without a visit to the local Java community, so I'll be talking at @devstaff_gr about #JavaNext in a few hours! Meet you there?

Had a great time talking about #JavaNext at @VoxxedZurich! For the parts that I had to skip (gimme 60 minutes, please! 😉), check out the slides:

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

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:

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

Learned a ton about Java these last two days at #JBCNConf? Top it off now in room 111 and let me tell you about #JavaNext: How projects Amber and Valhalla, Panama and Loom are about to change Java forever.

Looking forward to talking about #JavaNext at #DevoxxUK in 2h, but also sad that I won't get to see @heathriel's talk: How to Close the Diversity Gap (or, How Not to Perpetuate Bro Culture in Tech) I don't have a choice, but you do - choose wisely! 😉

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

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

In 30 minutes, I'll be on stage at #JavaZone to update a code base to Java after eleven. (Or will I? 🎃) Slides: Code base: If you have any questions, ask here or use #JavaNext.

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:

Here we go with @BrianGoetz' #JVMLS2019 talk on Project Valhalla: Gather around the fire and let me tell you a story about brave coders who tackle bytecodes, arrays, generics, and more to bring us flat and dense memory layout and 10x performance. 1/?

(4) Migration `Optional`, `LocalDateTime`, and other value-based classes ( want to be values. Will that work? Lots of uncomfortable questions to discuss and lots to do! 19/?

But remember, Brian implores, there's a working prototype. Try it and report your experience! And that's it on Valhalla for #JavaNext. Thanks to everyone working on this and particularly to @BrianGoetz for his updates. Kudos! 20/20

#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:
