#java21

Java Tip 💡 Since Java 21 ☕️ the most popular implementations of the Java Collection API like `ArrayList`, `LinkedHashMap`, or `LinkedHashSet` are sequential collections. #java #openjdk #java21 #collections

#Java21 has arrived in a production release with 15 features including virtual threads, a generational Z garbage collector, and a key encapsulation mechanism API. @InfoWorld takes a deeper look.

The road to #Java21 starts... now! 🚗 @nipafx gets you in the right lane by covering everything you need to know to update from Java 17 to 21.

Welcome Java 21. Goodbye "public static void main(String[] args){}." Yes, you read it right. Java is advancing and making it easier to write less code. Record, Pattern-matching, var, and switch expressions are some new features. [1/2] #Java21 #java #unnamedclasses

Sequenced Collections in #Java21 Introduce new interfaces to represent collections with a defined encounter order.

First in your 💕, always. Attend this panel session at #CloudWorld with the #Java team as they explore updates from #Java21 and growing the Java community.

#Java21 is gonna be big! One recent addition: // in void main() { System.out.println("Ha!"); } # run with java That's all it takes. 😮 More on that and the rest of the on-ramp in today's Newscast:

Will pattern matching in switch and record patterns finalize in #Java21? 😮 The latest JEPs no longer mark them as preview: * * I take that as a sign that it is at least under consideration. 🥳

Get back on the road to #Java21 with @JosePaumard, as he looks at Virtual Threads—how to use them and how they're working under the hood.

Inspired by a server challenge from @SinghDevHub I built a TCP web server using Java virtual threads (Project Loom) — and scaled it to 60,000+ clients on my laptop (Ryzen 5 5500U) Learned a lot about sockets & performance tuning,threading, & I/O bottlenecks. Blog soon #Java21

The Collections API got a big update in #Java21, adding new API that makes it easier to navigate and modify collections with a defined encounter order. @BillyKorando takes a look.

At #JForum Stockholm I showed a String template processor with some if/else branches. I got feedback they do not look elegant so...I refactored those to a nice exhaustive switch. Can you spot another preview feature of #Java21 in the switch expression?

The next #JEPCafe is almost out! It is about using Data Oriented Programming and plenty of other new features to solve the Countdown game. What about we take this coffee break together? I'll be there to chat with you! #Java #Java21
