Excellent responses, thank you jewelsea for your input it helped me a lot.

I updated the DigitalClock posted previously in a leaner format using Java 8. Using the additions of Java 8 like Date API and of course the lambdas.

 import javafx.animation.Animation;
 import javafx.animation.KeyFrame;
 import javafx.animation.Timeline;
 import javafx.scene.control.Label;
 import javafx.util.Duration;

 import java.time.LocalTime;
 import java.time.format.DateTimeFormatter;

 public class DigitalClock extends Label
 {
    private static DateTimeFormatter SHORT_TIME_FORMATTER =       DateTimeFormatter.ofPattern("HH:mm:ss");

    public DigitalClock()
    {
        bindToTime();
    }

    private void bindToTime() {
        Timeline timeline = new Timeline(new KeyFrame(Duration.seconds(0),
                                                      event -> setText(LocalTime.now().format(SHORT_TIME_FORMATTER))),
                                         new KeyFrame(Duration.seconds(1)));

        timeline.setCycleCount(Animation.INDEFINITE);
        timeline.play();
    }
}
