#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.

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:

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!

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.)

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`

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

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

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. 😉

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. 🧵

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

What a great day at @jdays2018! The slides for my talks are online: #Java11 Is Here! - Reactive HTTP/2 client, String/Optional improvements, and more #JavaNext - New Releases, Amber, Valhalla, And More Goodies

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! 😉

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

My talk on #JavaNext at #GeekOutEE starts in 15 minutes. Swing by room 1 to learn all about the interesting projects driving Java forward: Amber, Valhalla, Sumatra, ...

What is `size`? class WrappedList<T> implements List<T> { private List<T> inner; public int size() = inner::size; } It's a method with a "concise body", using the method reference syntax (lambda syntax would also be valid). #JavaNext

In a short interview with @InfoQ, @BrianGoetz comments on the proposal to allow hyphenated keywords in Java (e.g. `non-null` or `value-class`): The answer to `break-with` vs `yield` is interesting, too. #JavaNext

#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:

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?
