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.awt.geom;

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

public class DrawArc extends JComponent {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Draw Arc Demo");
        frame.getContentPane().add(new DrawArc());
        frame.setSize(new Dimension(420, 450));

    public void paint(Graphics g) {
        Graphics2D g2 = (Graphics2D) g;

        g2.setStroke(new BasicStroke(2.0f));
        g2.draw(new Arc2D.Double(50, 50, 300, 300, 0, 90, Arc2D.PIE));
        g2.draw(new Arc2D.Double(50, 50, 300, 300, 90, 90, Arc2D.PIE));
        g2.fill(new Arc2D.Double(50, 50, 300, 300, 180, 90, Arc2D.PIE));

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