Project Profile: What's OpenJDK? How does it work? What does it do? Here are the answers to these questions along with an exploration of JDK Enhancement Proposals, the Java Community Process, why there are so many JDK providers, and how long-term support works.

What is OpenJDK? - Inside Java Newscast #28

Data-Oriented Programming - Inside Java Newscast #29

Nicolai Parlog, Java Developer Relations

Data-oriented programming focuses on modeling data as data (instead of as objects). Records for data and sealed types for alternatives let us model immutable data where illegal states are unrepresentable. Combined with pattern matching we get a safe, powerful, and maintainable approach to ad-hoc polymorphism that lets us define operations on the data without overloading it with functionality.

Billy Korando, Java Developer Relations

Do you want to try something out in Java? Or experiment with a new feature or API? But don’t want to have to go through the ceremony of creating an application? Then you should consider JShell, Java’s REPL! Let’s look at it in this article.

HotSpot Deep Dive — Safepoint

Markus Grönlund, Consulting Member of Technical Staff

A safepoint is a global JVM state where the Java world is stopped. It is therefore safe, as in exclusive access, to inspect and process by the JVM. This concept is central to many runtimes providing some form of Automatic Memory Management. Learn how safepoints are implemented in the HotSpot Java Virtual Machine (JVM) and get introduced to to some related JVM concepts and structures.
