How do I draw an arc in Java 2D?

Arc2D is the abstract superclass for all objects that store a 2D arc defined by a framing rectangle, start angle, angular extent (length of the arc), and a closure type
(Arc2D.OPEN, Arc2D.CHORD, or Arc2D.PIE).

To constructs a new arc in double values, such as defining the specified location, size, angular extents, and closure type we can use the Arc2D.Double static-inner class.

package org.kodejava.example.awt.geom;

import javax.swing.*;
import java.awt.*;
import java.awt.geom.Arc2D;

public class DrawArc extends JApplet {
    @Override
    public void paint(Graphics g) {
        Graphics2D g2 = (Graphics2D) g;

        g2.setStroke(new BasicStroke(2.0f));
        g2.setPaint(Color.RED);
        g2.draw(new Arc2D.Double(50, 50, 300, 300, 0, 90, Arc2D.PIE));
        g2.setPaint(Color.GREEN);
        g2.draw(new Arc2D.Double(50, 50, 300, 300, 90, 90, Arc2D.PIE));
        g2.setPaint(Color.BLUE);
        g2.fill(new Arc2D.Double(50, 50, 300, 300, 180, 90, Arc2D.PIE));
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("Draw Arch Demo");
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

        JApplet applet = new DrawArc();
        frame.getContentPane().add(applet);
        frame.pack();
        frame.setSize(new Dimension(400, 450));
        frame.setVisible(true);
    }
}

Here is the result you’ll get when you run the snippet:
