Over the course of its runtime, this Transition generates a rotating animation. This is accomplished by routinely adjusting the node's rotation variable.
The angle measurement is given in degrees. If a fromAngle is not specified, the rotate value of the node is used instead. If toAngle is specified, it terminates there; otherwise, start value plus byAngle is used. If both toAngle and byAngle are provided, the toAngle takes precedence.

Rectangle rect = new Rectangle (100, 40, 100, 100);

rect.setArcWidth(50);
rect.setFill(Color.VIOLET);
RotateTransition rt = new RotateTransition(Duration.millis(3000), rect);
rt.setByAngle(180);
rt.setCycleCount(4);
rt.setAutoReverse(true);
rt.play();
