Here on foojay.io you can already find two posts by Carl Dea to get you started with JavaFX.

In this post, I want to show you yet another approach that uses the tools provided by Gluon, who are the maintainers, and the driving force behind OpenJFX.

The Gluon start website and the plugin allow you to get started with a new JavaFX project in a few clicks.

Thanks to the amazing work done by the Gluon team this also gives you a quick-start for the creation of a mobile application which can be built for both Android and iOS.

Ever since Java announced their 6-month release cycle, there is excitement around exploring new features and even more so with preview features.

Now, what is a record? It is a new variety of type declaration. It is also a sub-type of class. A common type of class, as we all know, is the data-carrier class. They are classes that have some fields and their corresponding getters and setters. They usually have little to no logic.

Records help provide a way to succinctly describe the intent of these data-carrier classes. A little less conversation, a little more action.

In this article, you’re presented with four short videos that will take you step-by-step through installing, writing, and deploying an application to Payara Server, even if you’ve never used the application server before.

Visit the Payara Getting Started page for further resources on getting started, including: Configuring, Adding a data source, Adding functionality, monitoring, security auditing, Creating a Restful Web Service, Logging, Testing Apps, etc.

Until recently, I last wrote Java in anger in 2002. IntelliJ IDEA had just been released; it wasn’t remotely on my radar. I honestly can’t remember what IDE we were using back then, but it certainly was a very long way to the fully featured IDE that JetBrains produce today.

Here’s my personal experience of using IntelliJ IDEA for the first time.

The “Hello World” version of electronics programming is a blinking LED. But, in this post, we will go a few steps further and control 8 LEDs inside a number display.

Igor De Souza, Dublin based Principal Big Data Consultant at Oracle, set up an interesting experiment in which he combines a LED number display with the Raspberry Pi and Quarkus.

I will demonstrate how to create a simple Web Service using Spring Boot.  This framework makes it almost effortless to develop web services, so long as the appropriate dependencies are in place.

In this example, I will create a Web Service that will read the current temperature from a file and make it available to clients via a RESTful endpoint.
