In the following code shows how to use Arc2D.equals(Object obj) method.

//from   w  w  w .  j  a  v a 2s  .c  o m
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Rectangle;
import java.awt.geom.Arc2D;

import javax.swing.JFrame;
import javax.swing.JPanel;

public class Main extends JPanel {

  public void paint(Graphics g) {
    Graphics2D g2 = (Graphics2D) g;
    int w = getSize().width;
    int h = getSize().height;

    Arc2D arc = new Arc2D.Double(0.0, 0.0, w, h, 0.0, 60.0, Arc2D.CHORD);
    System.out.println(arc.equals(new Arc2D.Double(0.0, 0.0, w, h, 0.0, 60.0, Arc2D.CHORD)));
    g2.draw(arc);

    arc = new Arc2D.Float(0.0f, 0.0f, w, h, 80.0f, 110.0f, Arc2D.PIE);

    g2.fill(arc);

    arc = new Arc2D.Float(0.0f, 0.0f, w, h, 210.0f, 130.0f, Arc2D.OPEN);

    g2.draw(arc);
  }

  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.getContentPane().add(new Main());

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(200, 200);
