Devoxx Belgium 2023, the premier Java developer conference, held in Antwerp, Belgium is an event we eagerly anticipate. As representatives of Payara, a sponsor of the conference, we had the privilege of attending this year's gathering, which took place at the iconic Kinepolis Antwerpen Cinema.

Pattern Matching for switch, introduced in Java 21 via JEP 441, marks a significant enhancement to the Java programming language, offering a more expressive and compact way to handle complex decision blocks. This feature extends the existing switch construct by allowing patterns in case labels, thus facilitating more concise, readable, and safe code when dealing with multi-way comparisons​​.

Java 21 introduces the Foreign Function and Memory (FFM) API, which allows Java programs to interoperate with code and data outside the Java runtime. Java operates within a managed environment known as the Java Virtual Machine (JVM). The JVM serves as an abstraction layer between the executing Java code and the underlying hardware and OS. One of the core design principles behind the JVM is to provide a secure and isolated environment for Java applications to run. This isolation is beneficial for several reasons, including security and stability; it mitigates risks such as unauthorized access to system resources or memory corruption, which could lead to vulnerabilities like buffer overflows.

In the ever-evolving landscape of enterprise applications, staying updated with the latest technologies is not just an option—it's a necessity for competitive advantage. The release of Jakarta EE 10 brought forth a myriad of enhancements that can significantly improve the scalability, security, and performance of your enterprise applications. But how do you make the transition smoothly? What are the best practices and strategies for upgrading?

In this recorded webinar tutorial - watch here -  we guide you through the essential steps and considerations for a successful upgrade. We will delve into the new features and improvements introduced in Jakarta EE 10 and why they make a compelling case for the upgrade.

Developers use MySQL databases in every corner of the world to create cloud-based applications. As they continually look for tools that offer better scalability, performance, and flexibility, many are pairing MySQL with the JSON data format.

Combined, these provide a wealth of benefits for developers. We’re going to briefly examine the ins and outs of MySQL and JSON to get you up to speed, then take a look at some of the things you can achieve using them together.

With Java 21 released today and Jakarta EE 11 slated for release in Q1 of 2024, the landscape for Java development is evolving rapidly, particularly in the cloud-native space. Although these two are not being developed together, they are intrinsically linked: Jakarta EE 11 will have Java 21 as its base Java SE version. This blog post will explore what these two significant releases bring to the table individually and how they can collectively enhance cloud native Java development.
