# How to create an Arc using JavaFX?

JavaObject Oriented ProgrammingProgramming

In general, an arc is a small segment of a curve. In JavaFX it is represented by the javafx.scene.shape.Arc class. This class contains six properties they are −

• centerX − This property represents the x coordinate of the center of the arc. You can set the value to this property using the setCenterX() method.

• centerY − This property represents the y coordinate of the center of the arc. You can set the value to this property using the setCenterY() method.

• radiusX − This property represents the width of the full ellipse of which the current arc is a part of. You can set the value to this property using the setRadiusX() method.

• radiusY − This property represents the height of the full ellipse of which the current arc is a part of. You can set the value to this property using the setRadiusY() method.

• startAngle − This property represents the starting angle of the arc in degrees. You can set the value to this property using the setStartAngle() method.

• length − This property represents the angular extent of the arc in degrees. You can set the value to this property using the setLength() 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.Arc;
import javafx.scene.shape.ArcType;
public class DrawingArc extends Application {
public void start(Stage stage) {
//Drawing a cubic curve
Arc arc = new Arc();
//Setting properties to cubic curve
arc.setCenterX(280);
arc.setCenterY(230);
arc.setStartAngle(45);
arc.setLength(100);
arc.setType(ArcType.ROUND);
//Setting other properties
arc.setFill(Color.CHOCOLATE);
arc.setStrokeWidth(8.0);
arc.setStroke(Color.BROWN);
//Setting the scene object
Group root = new Group(arc);
Scene scene = new Scene(root, 595, 300, Color.BEIGE);
stage.setTitle("Drawing arc");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]){
launch(args);
}
}
