So, you're a Java developer, or maybe you're aspiring to be one. Either way, you've probably faced the challenge of managing multiple versions of Java on your machine. One project requires Java 8, but another needs Java 11, yet another requires Java 17. The open-source library you're keen on contributing to needs yet another version. What do you do? You start juggling environment variables, and before you know it, your system is a tangled mess of configurations. Not fun, right?

And let's not even get started on the difference between JRE and JDK. It's easy for beginners to get confused about the distinction between the two. The JRE (Java Runtime Environment) is sufficient if you just want to run Java applications, but if you're going to be developing them, you'll need the JDK (Java Development Kit). The JDK includes everything the JRE has, plus additional tools and utilities for developers like the Java compiler, or javac.

Tired of all this complexity? Let me introduce you to SDKMan!, a version manager that streamlines the process, making it a breeze to manage multiple Java versions on your machine. Not just Java, SDKMan! can be used to manage a lot more kits and tools such as Maven. In this blog post however, we see how to use SDKMan! to effortlessly manage different versions of Java on the same machine.

Sealed classes are a powerful feature introduced in Java 15 that allows developers to control the inheritance hierarchy of a class. In this blog, we will explore the concept of sealed classes in the context of Jakarta EE, a set of specifications for building enterprise applications in Java.

Upcoming Java 21 brings a bunch of new features, including very interesting progress in concurrency. There are two main improvements – virtual threads and structured concurrency.

In this article, we discuss incoming usage of these enhancements inJakarta EE (formerly Java EE, now an open source project maintained by the Eclipse Foundation), a set of specifications that enables the worldwide community of Java developers to work on cloud native Java enterprise applications. Jakarta Concurrency is the concrete specification describing the expected behaviour.

The support in Jakarta EE is currently under development, details may change in the final implementation.
