A circle is a line forming a closed loop, every point on which is a fixed distance from a center point. A circle is defined by its center and radius: distance from the center to any point on the circle.
In JavaFX an ellipse is represented by the javafx.scene.shape.Ellipse class. This class contains four properties they are −
centerX − This property represents the x coordinate of the center of the ellipse, you can set the value to this property using the setCenterX() method.
centerY − This property represents y coordinate of the center of the ellipse, you can set the value to this property using the setCenterY() method.
radiusX − This property represents the width of the ellipse in pixels, you can set the value to this property using the setRadiusX() method.
radiusY − This property represents the height of the ellipse in pixels, you can set the value to this property using the setRadiusY() method.
To create a circle you need to −
Instantiate this class.
Set the required properties using the setter methods or, bypassing them as arguments to the constructor.
Add the created node (shape) to the Group object.
Example
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
import javafx.scene.shape.Ellipse;
public class DrawingEllipse extends Application {
public void start(Stage stage) {
//Drawing a Ellipse
Ellipse ellipse1 = new Ellipse();
//Setting the properties of the ellipse
ellipse1.setCenterX(200.0);
ellipse1.setCenterY(150.0);
ellipse1.setRadiusX(100);
ellipse1.setRadiusY(50);
//Setting other properties
ellipse1.setFill(Color.DARKCYAN);
ellipse1.setStrokeWidth(8.0);
ellipse1.setStroke(Color.DARKSLATEGREY);
//Drawing a Ellipse
Ellipse ellipse2 = new Ellipse();
//Setting the properties of the ellipse
ellipse2.setCenterX(450.0);
ellipse2.setCenterY(150.0);
ellipse2.setRadiusX(35);
ellipse2.setRadiusY(100);
//Setting other properties
ellipse2.setFill(Color.CHOCOLATE);
ellipse2.setStrokeWidth(8.0);
ellipse2.setStroke(Color.BROWN);
//Setting the Scene
Group root = new Group(ellipse1, ellipse2);
Scene scene = new Scene(root, 595, 300, Color.BEIGE);
stage.setTitle("Drawing an Ellipse");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]){
launch(args);
}
}Output
