JavaFX working with threads and GUI

Question

I have a problem while working with JavaFX and Threads. Basically I have two options: working with Tasks or Platform.runLater. As I understand

Answer 1

Use a Worker (Task, Service) from the JavaFX Application thread if you want to do something in the background.

Use Platform.runLater from a background thread if you want to do something on the JavaFX Application thread.
