Isn't that just generic notation saying it takes an event handler where you indicate \
the specific type.

e.g. this https://docs.oracle.com/javafx/2/events/handlers.htm \
<https://docs.oracle.com/javafx/2/events/handlers.htm> includes

node.addEventHandler(DragEvent.DRAG_ENTERED, 
                    new EventHandler<DragEvent>() {
                        public void handle(DragEvent) { ... };
                    });

showing that this handler is for DragEvent's, specifically the DRAG_ENTERED event in \
this case.  So you need to pass your own handler as that parameter.
