Data Binding with Low-level binding API in JavaFX

Demo Code

import javafx.beans.binding.DoubleBinding;
import javafx.beans.property.DoubleProperty;
import javafx.beans.property.SimpleDoubleProperty;

public class Main {

  public static void main(String[] args) {
    // volume = 4/3 * pi r^3
    final DoubleProperty radius = new SimpleDoubleProperty(2);

    DoubleBinding volumeOfSphere = new DoubleBinding() {
      {/*from w  w  w .j a va 2  s  .c o m*/
        super.bind(radius);
      }

      @Override
      protected double computeValue() {
        return (4 / 3 * Math.PI * Math.pow(radius.get(), 3));
      }
    };

    System.out.println("Current - radius for Sphere: " + radius.get());
    System.out.println("Current - volume for Sphere: " + volumeOfSphere.get());


    radius.set(50);
    System.out.println("After - radius for Sphere: " + radius.get());
    System.out.println("After - volume for Sphere: " + volumeOfSphere.get());
  }
}
