public class FadeTransitionExample extends Application { 
   @Override 
   public void start(Stage stage) {
      //Drawing a Circle 
      Circle circle = new Circle(); 
      
      //Setting the position of the circle 
      circle.setCenterX(300.0f);  
      circle.setCenterY(135.0f); 
      
      //Setting the radius of the circle 
      circle.setRadius(100.0f); 
      
      //Setting the color of the circle 
      circle.setFill(Color.BROWN); 
      
      //Setting the stroke width of the circle 
      circle.setStrokeWidth(20); 
       
      //Creating the fade Transition 
      FadeTransition fadeTransition = new FadeTransition(Duration.millis(1000)); 
      
      //Setting the node for Transition 
      fadeTransition.setNode(circle); 
      
      //Setting the property fromValue of the transition (opacity) 
      fadeTransition.setFromValue(1.0); 
      
      //Setting the property toValue of the transition (opacity) 
      fadeTransition.setToValue(0.3); 
      
      //Setting the cycle count for the transition 
      fadeTransition.setCycleCount(50); 
      
      //Setting auto reverse value to false 
      fadeTransition.setAutoReverse(false); 
  
      //Playing the animation 
      fadeTransition.play(); 
         
      //Creating a Group object  
      Group root = new Group(circle); 
         
      //Creating a scene object 
      Scene scene = new Scene(root, 600, 300); 
      
      //Setting title to the Stage 
      stage.setTitle("Fade transition example"); 
         
      //Adding scene to the stage 
      stage.setScene(scene); 
         
      //Displaying the contents of the stage 
      stage.show(); 
   }      
   public static void main(String args[]){ 
      launch(args); 
   } 
}
