Add Area of Two Figures


This section illustrates you how to add area of two specified figures in Graphics.

In the given example, the classes Rectangle2D and Ellipse2D are provided by the package java.awt.geom.*. These classes provides the shape rectangle and oval respectively. Object of class Area is created to pass the object of class Shape into its constructor. Set the size of rectangle with rect.setFrame(150, 150, 150, 100) and size of oval with oval.setFrame(100, 100, 150, 100). 

Following method adds the area of two shape:


Here is the code of

import java.awt.*;
import java.awt.event.*;
import java.awt.geom.Area;
import java.awt.geom.Ellipse2D;
import java.awt.geom.Rectangle2D;
import javax.swing.*;

 public class AddAreaExample extends JApplet {
  Rectangle2D.Double rect = new Rectangle2D.Double();
  Ellipse2D.Double oval = new Ellipse2D.Double();
  Area area1; 
  Area area2;

  public void init() {
 public void paint(Graphics graphics) {
  Graphics2D graphics2d = (Graphics2D) graphics;
  rect.setFrame(150, 150, 150, 100);
  oval.setFrame(100, 100, 150, 100);
  area1 = new Area(rect);
  area2 = new Area(oval);
 public static void main(String s[]) {
  JFrame frame = new JFrame("Add Area");
  frame.addWindowListener(new WindowAdapter() {
  public void windowClosing(WindowEvent e) 
  JApplet applet = new AddAreaExample();
  frame.getContentPane().add("Center", applet);
  frame.setSize(new Dimension(350,300));;
