Nice thank you, I've been considering playing around with JavaFX for quite some time. Do you have any advice for someone getting started who has quite a bit of Swing experience but no JavaFX?
I think the best way to get started would be to download the sampler application from https://github.com/mkpaz/atlantafx. That is state of the art, good implementation. You can play around with it and jump to the source code to see how it is implemented. It contains almost everything an application needs.
Also depending how old your general Java knowledge is, the modern way of creating applications is through the module system and the jlink/jpackage tools. There are many outdated solutions for application packaging out there as well. If anything you see is using the classpath, builds jars or fat jars, or is using external tools outside the JDK, it's probably old and no longer appropriate.
