How does a community of Java enthusiasts drive innovation for 15 years, turning ideas into designs into code into features you can use in your IDE. OpenJDK is one of the world's most influential open source communities. It drives the reference implementation of Java SE and the Java Virtual Machine, a programming language and runtime environment used daily by millions of software developers. More than that, the community drives its innovation - 15 years and counting of new language features, core library additions, performance improvements, runtime enhancements, and new tooling. But how does it ..read more

Oracle will contribute GraalVM's just-in-time compiler and native image technology to OpenJDK. It will also create EA and GA builds for JavaFX 20+ and is hard at work at creating generational ZGC to vastly improve ZGC's already impressive performance. And then there's the Java SE Subscription Enterprise Performance Pack, a drop-in replacement for JDK 8 with JDK 17 performance. Intro Welcome everyone to the Inside Java Newscast, where we cover recent developments in the OpenJDK community. I'm Nicolai Parlog, Java developer advocate at Oracle, and today we're gonna look into JavaFX EA builds, Gr ..read more

Visibility, classes, methods, instance and static members, parameters - a newcomer to programming needs to learn all of these concepts to truly understand a simple hello-world program in Java. Time to make that simpler and cut down on what needs to be known up front. Intro Welcome everyone to the Inside Java Newscast, where we cover recent developments in the OpenJDK community. I'm Nicolai Parlog, Java developer advocate at Oracle, and today we're gonna look at how the smallest possible Java program may soon turn from "public class Hello public static void main String bracket bracket args" to ..read more

Project Amber steadily and carefully chips away at Java's persistent pain points. This talk discusses released, previewing, and upcoming features achieve that and make Java more expressive, more succinct, and more readable. Java has issues! Verbose, cumbersome, no expressiveness, no fun. (Or so the kids say.) Jokes and the craving for syntax sugar aside, Java does have some persistent pain points and Project Amber was set up to tackle them. Not as a single solution to a narrow problem, but as a solution factory that's steadily and carefully chipping away at them: text blocks and interpolation ..read more

Among other things, Java 19 ships with virtual threads, structured concurrency APIs, sealed types, and pattern matching in switch - all of them as previews, but still very cool! I'm using these features here to create a GitHub crawler. This episode was not scripted and so there's no written version of what I said. Another one you gotta watch. ?

String templates make it easy and safe to embed variables and expressions in strings; JavaFX 19 comes with many improvements, chief among them derived observables; and the deserialization filter can keep apps safe from certain attacks. More on all of this at JavaOne! Welcome everyone to the Inside Java Newscast, where we cover recent developments in the OpenJDK community. I'm Nicolai Parlog, Java developer advocate at Oracle, and today I have another JavaOne-inspired mix of topics for you, namely string templates, the deserialization filter, and JavaFX 19.

Sequenced collections introduce an abstraction for collections with a known encounter order like all lists and some sets and maps. It will be easy to add, get, or remove the first and last elements and to iterate or stream in reverse order. We're also discussing immutable collections and pure functions. More on all of this at JavaOne! Welcome everyone to the Inside Java Newscast, where we cover recent developments in the OpenJDK community. I'm Nicolai Parlog, Java developer advocate at Oracle, and today we're gonna look at sequenced collections and the meaning of immutability and purity. And i ..read more
