3 Downloading JavaFX
Download the JavaFX SDK from JavaFX Downloads. You can also download JavaFX JMOD files as a compressed archive file, which you can use to create a custom runtime image for your JavaFX application. See Creating a Custom JRE for a JavaFX Application.
After downloading the JavaFX SDK or the JavaFX JMOD archive file, unzip it or extract its files into a directory on your computer.
