  • Java 17 on the Raspberry Pi

    As part of the Foojay Virtual OpenJDK 17+ JUG Tour, I was asked to present the state of Java and JavaFX 17 on the Raspberry Pi.

    So, a perfect opportunity to freshen up my #JavaOnRaspberryPi presentation with some hot-off-the-press versions.

  • Learn JShell with JavaFX in 60 Seconds

    We started with an introduction of the basics of using jshell. Next, you got a chance to learn how to run a JavaFX application file from a terminal command prompt and from within jshell’s command prompt.

    After that, launching the application we were able to change the color interactively by setting the public static member variable color.

    Lastly, we learned how to stop a JavaFX application properly via /reset command.

  • JDKMon: Your Friendly JDK Distribution Updater

    JDKMon is just a little tool that scans your computer for installed OpenJDK distributions and uses the Disco API to check whether there are updates available for one of the distributions.

    In case it finds updates it will present you buttons for each package it finds.

    When you click on one of these buttons (e.g. tar.gz, zip, pkg etc.) you have to select a folder where the selected package should be downloaded to.

  • Java in Education: Combining Java with Raspberry Pi and the Pi4J Library

    Although a lot of universities and high schools focus on Python and C# in their program, there are luckily a lot of others who go “full Java”.

    Don’t get me wrong, I definitely don’t want to start a “programming-languages-war”, but Java is the language I used myself more than any other for the last 10 years.

    Setting up a new project or building a proof-of-concept for a new idea, is a matter of hours. And there is always a solution for the problem I need to solve.

    This is probably true for each developer who has enough experience in the language used the most. But having used and experimented with many other languages, I still keep returning to my “one true love”, being Java, as it always delivers the result I’m aiming for, with the right amount of code to be readable, understandable, and testable!

  • Creating a JavaFX World Clock from Scratch (Part 6)

    Hello, and welcome to the last part of this series of articles on creating a JavaFX World Clock from scratch!

    In this part, I will show you how to make WebService calls (RESTful) to retrieve weather data based on geographic locations.

    If you remember, in Part 5 you learned how to use the JavaFX WebView and the popular mapping library Leaflet JS enabling the user to discover geographic locations. In Part 6, I will show you how I used Java 11’s Http Client to retrieve and display weather content. If you are new to this series, you can visit Part 1-5.

  • How to Create Mobile Apps with JavaFX (Part 3)

    In Part 1, we introduced a mobile app game, TiltMaze, written completely in JavaFX, which you can download from either the Apple App Store or Google Play and install it on your mobile device or tablet.

    In Part 2, we showed you how to work with Gluon and GraalVM to build native images that execute on either Apple or Android mobile devices and tablets.

    In this article, we’ll discuss how to upload your application to the respective mobile app stores so the world can install your application on their devices.

  • How to Create Mobile Apps with JavaFX (Part 1)

    In this three-part series, I’ll show how to use JavaFX for mobile app development: JavaFX looks great and runs on both mobile platforms.

    You use the same JavaFX code targeting Google Play and Apple App stores. Performance is excellent and startup time is fast with native images.

    You use Java 11+ and the latest JavaFX.

    Our game is TiltMaze Labyrinth!

  • JavaFX: Gluon Status Update, Dual Screen on Raspberry Pi Sample, IntelliJ New JavaFX Project Wizard

    Since Java switched to a 6-month release cycle, JavaFX has done the same, so next version will be number 17.

    Keep in mind, although Java and JavaFX are on the same version-number, you can still use Java 11 and combine it with the JavaFX 17 runtime if you want to benefit from its improvements. Up till now, there were no breaking changes in either of the frameworks which force you to use a Java-version higher than 11.

  • Interviews with Robert Savage and Johan Vos on the State of Java on Raspberry Pi

    Here on Foojay.io, you can find already a long list of articles about Java on the Raspberry Pi.

    As you may know, already I’m a big fan of this combination. The Raspberry Pi on one side is a very cheap computer that allows you to experiment with electronic components thanks to the Pi4J library.

    And on the other hand, JavaFX is the ideal framework to build user interfaces that can directly control these components, all in one application!

    But maybe you don’t have / want to believe me? So let’s ask two experts what they think is the future of #JavaOnRaspberryPi.

  • Creating a JavaFX World Clock from Scratch (Part 5)

    Hello, and welcome back to this series of articles on creating a JavaFX world clock.

    In Part 5 below, we will be looking at JavaFX’s WebView API to display an HTML Web page containing a 2D map (Mercator projection).

    To render the 2D map I will be using the popular Leaflet JS library. This will enable the World Clock App to let the user explore map locations based on GPS coordinates (latitude & longitude).
