Starting JDK15, ZGC is no longer an experimental feature. ZGC is a low latency garbage collector in Java that keeps pause times to no greater than 10ms and is a great option for heap spaces running to terabytes. #Java #ZGC #JDK15

First or Last access out of the box from Java 21 onwards! [Github code in comments] Sequenced Collections """ Introduce new interfaces to represent collections with a defined encounter order. Each such collection has a well-defined first element, second element, and so forth, up to the last element. It also provides uniform APIs for accessing its first and last elements, and for processing its elements in reverse order. """ Sunit Ghosh #java #jdk #jdk21 #OpenJDK #java21 

Java 21 enters the release candidate stage with 15 finalized features including virtual threads, a generational Z garbage collector, and a key encapsulation mechanism API. #onetikk #JDK21 #JDK #javavirtualmachine #java21

Virtual Threads are one of the most anticipated and exciting new features of the just released JDK 21. They mark a significant milestone in Java's journey to support highly concurrent and scalable applications. Do you already plan to adopt them? Does it make the difference for your project and tip the scale in favour of Java when considering Node? #RoadTo21 #java #jdk21 #development

Java 22 brings back Structured Concurrency as Second Preview Code available at: github -> engineersunit/java-twenty Attaching a doc which explains code run on JDK20 ✅ Improves reliability ✅ Enhances observability ✅ Streamlines error handling and cancellation ✅ Eliminate risks of thread leaks and cancellation delays ✅ Treats multiple tasks running in different threads as a single unit of work ✅ Used to ensure that the lifetime of a concurrent operation is confined by a syntax block, just like that of a sequential operation in structured programming Background ✅ JDK 19: Delivered as an incubating API ✅ JDK 20: Reincubated with update to inherit scoped values ✅ JDK 21: Previewed with changes to StructuredTaskScope fork() ✅ JDK 22: Previewed without changes ⏰ To be noted:  It first previewed in JDK 21 via JEP 453 with StructuredTaskScope::fork(...) changed to return a Subtask rather than a Future The code in the github is the JDK 20 version with return type as Future.

As per the release schedule, JDK 21 will be formally released today! The final set of 15 new features, in the form of JEPs, can be separated into four categories: Core Java Library, Java Language Specification, HotSpot and Security Library! #java21 #jdk #craftsmanship #raisingthebar

No, it is not dear.....It is the JDK21 that deprecates the URL class's constructors and certainly not the good old JDK8. Interestingly this particular LLM tool took one of StackOverflow's answers to build an inference to the prompt's response. https://lnkd.in/e7nuafXj Perhaps the question is too generic or something else..

Come 2023/09/19 YOU need to deal with the Ultimate Conundrum - "With Great Power Come Great Responsibility" Java 21 - Virtual Threads is handing Java Developers around the globe a formidable feature where millions of threads can be let loose in your application How do you plan to put a leash on this BEAST of a feature? OpenJDK team has bestowed upon the following magical stuffs (JVM system properties) 👉 jdk.virtualThreadScheduler.parallelism The number of platform threads available for scheduling virtual threads. It defaults to the number of available processors 👉 jdk.virtualThreadScheduler.maxPoolSize The maximum number of platform threads available to the scheduler 👉 jdk.virtualThreadScheduler.minRunnable The minimum number of platform threads available to the scheduler #OpenJDK #Java21 #JDK21 #OpenJDK21 #JavaVirtualThreads

callin out all #javadevelopers the beast is out this new feature makes javas power unparalleled in comparison to any other language or tool check this out #jdk21 #java #multithreading
