In this example we show how the Set operations going to make a union of 2 circles. Union exclusive (XOR ) examples how the code as follows:

import java.applet.Applet;

import java.awt.*;
import java.awt.event.*;
import java.awt.Color;
import java.awt.Graphics;
import javax.swing.*;
import java.awt.geom.*;
import java.awt.image.*;
public class DrawexclusiveOrExample extends Applet {
public static void main(String[] args) {
Frame DrawexclusiveOr = new Frame("Draw exclusiveOr Example");
DrawexclusiveOr.setSize(350, 250);
Applet DrawexclusiveOrExample = new DrawexclusiveOrExample();
DrawexclusiveOr.add(DrawexclusiveOrExample);
DrawexclusiveOr.setVisible(true);
DrawexclusiveOr.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
      }
    });
  }
  public void paint(Graphics g) {
    g.setColor(Color.blue);
    g.setFont(new Font("Arial",Font.BOLD,14));
    g.drawString("Draw exclusiveOr Example", 50, 40);
    g.setFont(new Font("Arial",Font.BOLD,10));
    g.drawString("http://ecomputernotes.com", 200, 205);
                Graphics2D G2D = (Graphics2D)g;
                GradientPaint GPaint = new GradientPaint(50.0f, 50.0f, Color.red,200.0f, 50.0f, Color.green);
                G2D.setPaint(GPaint);
                Ellipse2D E2D = new Ellipse2D.Double(50.0, 50.0, 80.0, 80.0);
                Ellipse2D E2D2 = new Ellipse2D.Double(100.0, 50.0, 80.0, 80.0);
                Area area1 = new Area(E2D);
                Area area2 = new Area(E2D2);
                area1.exclusiveOr(area2);
                G2D.fill(area1);
  }
}
