JavaFX Cirlce

A circle is a special type of ellipse with both of the focal points at the same position. Its horizontal radius is equal to its vertical radius. JavaFX allows us to create Circle on the GUI of any application by just instantiating javafx.scene.shape.Circle class. Just set the class properties by using the instance setter methods and add the class object to the Group.

Properties

The class properties along with the setter methods and their description are given below in the table.

Property	Description	Setter Methods
centerX	X coordinate of the centre of circle	setCenterX(Double value)
centerY	Y coordinate of the centre of circle	setCenterY(Double value)
radious	Radius of the circle	setRadius(Double value)

Example:

package application;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
import javafx.stage.Stage;
public class Shape_Example extends Application{

	@Override
	public void start(Stage primaryStage) throws Exception {
		// TODO Auto-generated method stub
	primaryStage.setTitle("Circle Example");
	Group group = new Group();
	Circle circle = new Circle();
	circle.setCenterX(200);
	circle.setCenterY(200);
	circle.setRadius(100);
	circle.setFill(Color.RED);
	group.getChildren().addAll(circle);
	Scene scene = new Scene(group,400,500,Color.GRAY);
	primaryStage.setScene(scene);
	primaryStage.show();
}
public static void main(String[] args) {
	launch(args);
}
