Have fun with this overview of the “JavaFX LinksOfTheWeek” that got published on jfx-central.
Thanks to the Devoxx conference, there are many hours you can spend on JavaFX-related videos!
On July 15th of 2023, I published a post here about my initial experiments with CRaC on the Raspberry Pi.
One of the most “fancy” electronic components is definitely a LED strip.
These are all the links of my presentation at Devoxx Belgium, Wednesday 12:00-12:50, Room 7.
This month OpenJDK and OpenJDK 21 got officially released, so links to the new downloads but also to the early access builds of the next one!
Java 21, released on September 19th, 2023, brings many new features, 8 which are fully integrated and 7 which are incubator or preview.
Just like Foojay wants to be the starting place for all info related to Java, JFX Central is the place to be for all JavaFX info.
I’ve taken a holiday this month, so probably missed a lot of the amazing JavaFX news, but still some things caught my attention and you can find them in this LinksOfTheMonth overview.
Yes, the Raspberry Pi Operating System is awesome! But the Pi4J project made it if even more awesome by adding “goodies” for Java developers!
Although I skipped a few weeks because of busy schedules, holiday interruptions, and too few hours in a day, there was still a lot to report in the two #LinksOfTheWeek that were published on jfx-central.
Reading the temperature, humidity, and pressure from a BME280 Sensor with Java, Pi4J, I2C, SPI, and JBang
To make it as easy as possible to get started with Java on the Raspberry Pi to interact with electronic components, I started a new section on the Pi4J website with JBang examples.
Again a lot has been shared this month in the jfx-central.
With the April release of the Zulu Build of OpenJDK, Azul announced the integration of CRaC in its version 17 of Java for Linux.
Writing has always been my passion, and even in my previous jobs as a developer, I stood out as the one who enjoyed creating and maintaining documentation.
Again a busy month in JavaFX-world! Here is a nice list with links for your reading and clicking pleasure!
Some time ago on Twitter, I discovered @OrangoMango, who shared his progress in creating a 3D engine with JavaFX.
This is the summary of the #LinksOfTheWeek as published on jfx-central.
Interview by Bazlur Rahman: Unlocking Java Secrets with Frank Delporte - Insights, Stories, and Tips for Success
On Foojay.io, Bazlur Rahman is publishing a series of interviews with various people from the OpenJDK community.
This is the summary of the #LinksOfTheWeek as published on jfx-central.
Let’s take a look at the power and beauty of what Java Enums can provide…
Hone your software design skills by implementing popular design patterns in Java This book is for sale on Amazon in Kindle and Paperback editions.
February is a short month, but this list seems to be longer than ever… A lot of game development, releases, interesting ongoing development, and so much more to read.
2023 has taken off with a flying start in JavaFX-world!
Foojay.io aims to be the starting point for “all-things OpenJDK,” but during one of my morning walks the idea struck me that this site really needs complete beginner materials, too.
If anyone needs a reminder Java and JavaFX are “alive and kicking”, you can not only check out jfx-central.
Exactly one year ago, in December 2021, I published three articles of MQTT messaging with Raspberry Pi, Raspberry Pi Pico and HiveMQ Cloud.
The end of the year is approaching, so it’s time to start scheduling your holidays for the next year.
Time flies when having fun… So here we are again, another month has passed and this is a summary of the Links Of The Week that were published on jfx-central.
After my talk at J-Fall I got the question what is required to get started with #JavaOnRaspberryPi.
When I (re)started the JavaFX Links Of The Week on jfx-central.
This summer I read the book “Entreprenerd” by Bruno Lowagie. It tells the story of how he started with the iText PDF Java library and turned that into a company together with his wife, and eventually sold it with all problems related to most sales and acquisitions trajects… In “Entreprenerd”, he also describes the process of writing two books about the iText library itself, as there were no good manuals available and he wanted to liberate himself from the ever-returning same questions.
Links used in my talks at Devoxx 2022 (Antwerp, Belgium) and J-Fall (Ede, The Netherlands).
The JavaFX links of the week are back on jfx-central.com, and here we collect the complete month for you in an excellent overview.
It has been a while since I last had to create documents in a program, and iText has been “on my radar” to try out for a while now.
As I’m becoming a senior developer in terms of age, I’ve transitioned from one language to another.
If you create a new SD card for a Raspberry Pi with the operating system, you can choose the “Raspberry Pi OS Full (32-bit)” edition, which includes Java 11.
On the OpenJFX website you can find a lot of getting started documentation.
In the previous two posts in this series, we used Java on the Raspberry Pi mini-computer to send sensor data to HiveMQ Cloud, and visualize it on a dashboard.
In the previous post we started our discovery of HiveMQ Cloud with Java on the Raspberry Pi.
A few years ago I did my first experiments with an MQTT server (Mosquitto) running on a Raspberry Pi to connect an Arduino and Raspberry Pi for the drumbooth of my son.
The Raspberry Pi in combination with an inexpensive touch screen, makes a perfect controller for a machine or game console.
In a previous post “Getting Started with FXGL Game Development” we already have taken a look at the FXGL game development framework developed by Almas Baimagambetov.
Are you a serious Java-developer looking for a fun project? Or want to learn something completely new and use your Java-knowledge to control electronic components?
Today I could give my talk “Having fun with Java and JavaFX on the Raspberry Pi” at the JFXDays.
Building native applications for all PC and mobile platforms from a single JavaFX project with Gluon Mobile and GitHub Actions
The post “Starting a JavaFX Project with Gluon Tools” shows you how to start a Gluon Mobile Multiview project with a few clicks in IntelliJ IDEA thanks to the “Gluon plugin”.
On foojay.io you can already find two posts by Carl Dea to get you started with JavaFX:
Today I had my first Devoxx talk, after my Java virtual talk a few weeks ago at the “Oracle Groundbreakers APAC Virtual Tour 2020” conference (21/10)!
Confused about the release cycles of OpenJDK and OpenJFX and the relationship between them?
After my virtual conference talk “Java and JavaFX on the Raspberry Pi” at the “Oracle Groundbreakers APAC Virtual Tour 2020”, I got in touch with some people who were working on JavaFX 3D in the past, and were curious how that would behave on the Raspberry Pi.
Today I had the honor to speak at the “Oracle Groundbreakers APAC Virtual Tour 2020” conference.
The OpenJDK sources are now fully available and developed on GitHub as a result of Project Skara.
In my book “Getting Started with Java on the Raspberry Pi”, I give more info about IDEs (= Integrated Development Environment) for Java development.
A topic which comes up from time to time in questions related to Java and the Raspberry Pi, is the support of the 4th version of this board in combination with Pi4J, “the friendly object-oriented I/O API and implementation library for Java programmers to access the full I/O capabilities of the Raspberry Pi “.
A micro SD card is the default way to add an operating system to the Raspberry Pi.
Thanks to Twitter and LinkedIn I got into contact with several developers who are doing Java stuff on Raspberry Pi and I want to share those projects with you as they can be an inspiration for all of us to get started with Java development on the Raspberry Pi.
For this post I did some experiments with Java 15, reusing the Ubuntu 64bit SD card which was also used for the earlier post “Comparing a REST H2 Spring versus Quarkus application on Raspberry Pi”.
In this article “Java vs Python - Which Programming Language Should Programmer Learn First?
In a previous post “Installing Java and JavaFX on the Raspberry Pi”, you can read how to install BellSoft LibericaJDK to be able to run JavaFX applications with a graphical user interface on a Raspberry Pi with ARMv7 or ARMv8 processor.
Goal of this comparison In my previous post “A Spring REST and H2 database application on the Raspberry Pi” an example was described to store sensors and measurements in a H2-database through REST API’s with a Spring application on the Raspberry Pi.
Java on Raspberry Pi The “Pi” in the name of the Raspberry Pi refers to Python, but as a Java developer I love to know and experiment with the various Java frameworks I also use at work.
In my book “Getting Started with Java on Raspberry Pi” I dedicated a chapter on Pi4J, the leading framework to combine the power of Java with the hardware capabilities of the Raspberry Pi.
In “The MagPi Magazine” #93 and #94, published by the Raspberry Pi Foundation, you can find two articles which describe how you can get started with Java, Maven, Visual Studio Code and Pi4J on the Raspberry Pi.
FXGL is a Java, JavaFX and Kotlin Game Library (Engine) made by Almas Baimagambetov.
One of the most read articles on this blog is about the installation of a recent Java on Raspberry Pi (March 13, 2019), so it’s time for an update!
Based on multiple examples from my book “Getting started with Java on Raspberry Pi”, I created a touchscreen controller for the drum booth of my son.
While looking for a cheap and nice component to demonstrate the use of SPI (Serial Peripheral Interface) I found out this 8x8 matrix LED display on a board with a MAX7219 chip is the perfect piece of hardware!
Pi4J contains helper methods to minimize the work needed to use certain hardware modules on the Pi with Java.
Trisha Gee (Coder, blogger, speaker, Developer Advocate at JetBrains, @trisha_gee), which I interviewed for “Chapter 4: Choosing an IDE”, and Josh Long (Spring Developer Advocate at Pivotal, @starbuxman) worked together on a blog series in which they showed the power of reactive data produced by a Spring application.
In my book I explain the use of bits and bytes by using a shift register SN74HC595 IC and 5101AS LED number display.
To create some timeline images for my book, I created this little JavaFX application to be able to easily update the content and recreate the image.
Using the Java library I created (see previous post), it was a piece of cake to create a JavaFX UI on top of it!
Next step in my book progress, is getting more into the details of hardware components.
The best way to understand and learn something new, is to document it yourself.
One of the example applications in my book “Getting started with Java on the Raspberry Pi” combines a JavaFX application with Mosquitto on the Raspberry Pi to control a LED strip with an Arduino.
A story of bits, bytes, signed and unsigned Some time ago there was a question on the Pi4J-forum caused by some confusion about a numeric value handled as a byte which was logged as a negative number -86 instead of the expected value 170.
My very first open source JavaFX library is now available in the Maven repository!
Great move of Microsoft! They provide an all-in-one installer for Java dependencies and Visual Studio Code.
What is Pi4J See https://www.pi4j.com/1.2/index.html This project is intended to provide a friendly object-oriented I/O API and implementation libraries for Java Programmers to access the full I/O capabilities of the Raspberry Pi platform.
As I was learning Spring Boot myself, I thought the easiest way to learn was trying to build an example and write about it.
While trying out what Pi4J can do, I found it could easily be extended with a JavaFX application to provide info about the headers on a Pi board.
As my daily work mainly is Java and back-end stuff on “real servers”, I set myself for 2019 as a personal goal to experiment with Java 11 on a Raspberry PI.
What we will do Based on the previous blog posts
In part 2 of this blog series Java 11 was successfully installed on a PI.
I prefer a Java app above a web app, because starting a new “modern” web development requires you to pull a bunch of dependencies and a lot of files before you can start.
What is JavaFX? From the Oracle site: “JavaFX is a set of graphics and media packages that enables developers to design, create, test, debug, and deploy rich client applications that operate consistently across diverse platforms.
After my first (and failed) attempt to get Java 11 running on an old Raspberry PI, I bought a brand new 3 Model B+ version.
One of my goals for 2019 is experimenting with the latest Java and JavaFX versions on a Raspberry PI.
