JavaFX is a set of software APIs and tools that delivers desktop applications and rich internet applications (RIAs) that can run most anywhere Java runs. JavaFX applications run on Windows, MacOS, iOS, Android, Linux, and many other operating systems. JavaFX replaces Swing and the older AWT as Java SE’s GUI.

This short JavaFX tutorial goes into the three most common FileChooser uses. They are:
