Set operations Subtraction Java Example

In this example we show how the Set operations going to make a Subtraction of 2 circles . Subtraction 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 DrawsubtractExample extends Applet { 
 public static void main(String[] args) { 
 Frame Drawsubtract = new Frame("Draw subtract Example"); 
 Drawsubtract.setSize(350, 250); 
 Applet DrawsubtractExample = new DrawsubtractExample(); 
 Drawsubtract.add(DrawsubtractExample); 
 Drawsubtract.setVisible(true); 
 Drawsubtract.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 subtract 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.subtract(area2); 
                 G2D.fill(area1); 
   } 
 }
