JavaFX | Arc with examples

Arc class is a part of JavaxFX. Arc class creates an arc on some given values specified, such as center of the arc, the start angle, the extent of arc(length), and radius. Arc class extends Shape class.

Constructor for the class are

1. Arc(): creates an empty instance of arc class
2. Arc(double centerX, double centerY, double radiusX, double radiusY, double startAngle, double length): creates an arc with given coordinates and values

commonly used methods

Method	Explanation
getCenterX()	returns the x coordinate of the center of arc
getCenterY()	returns the y coordinate of the center of arc
getRadiusX()	returns the x coordinate of the radius of arc
getRadiusY()	returns the y coordinate of the radius of arc
getStartAngle()	returns the start angle of the arc
getType()	Gets the value of the property type.
setCenterX(double v)	sets the x coordinate of the center of arc
setCenterY(double v)	sets the y coordinate of the center of arc
setLength(double v)	sets the length of the arc
setRadiusX(double v)	sets the X radius of the arc
setRadiusY(double v)	sets the y radius of the arc
setStartAngle(double v)	sets the start angle of the arc
setType(ArcType v)	sets the arc type of the arc

The following programs will illustrate the use of the Arc class

Java program to create a arc
This program creates a Arc indicated by the name arc( center, radius, start angle and arc length is passed as arguments). The arc will be created inside a scene, which in turn will be hosted inside a stage. The function setTitle() is used to provide title to the stage. Then a Group is created, and the arc is attached.The group is attached to the scene. Finally, the show() method is called to display the final results.

// Java program to create a arc
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.shape.DrawMode;
import javafx.scene.layout.*;
import javafx.event.ActionEvent;
import javafx.scene.shape.Arc;
import javafx.scene.control.*;
import javafx.stage.Stage;
import javafx.scene.Group;
public class arc_0 extends Application {

    // launch the application
    public void start(Stage stage)
    {
        // set title for the stage
        stage.setTitle("creating arc");

        // create a arc
        Arc arc = new Arc(100.0f, 100.0f, 100.0f, 100.0f, 0.0f, 100.0f);

        // create a Group
        Group group = new Group(arc);

        // translate the arc to a position
        arc.setTranslateX(100);
        arc.setTranslateY(100);

        // create a scene
        Scene scene = new Scene(group, 500, 300);

        // set the scene
        stage.setScene(scene);

        stage.show();
    }

    public static void main(String args[])
    {
        // launch the application
        launch(args);
    }
}
