Show Intersection between the Area of two Shapes
This section illustrates you how to show the intersection between the
area of shapes in Graphics.
Intersection means 'the common part'. Classes Rectangle2D and Ellipse2D
are provided by the package java.awt.geom.*. These classes provides the shapes rectangle and oval respectively. Object of
Area class is
created to pass the object of shape class 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 code shows the
intersection between the two shapes:
Here is the code of IntersectAreaExample.java
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 IntersectAreaExample extends JApplet {
Rectangle2D.Double rect = new Rectangle2D.Double();
Ellipse2D.Double oval = new Ellipse2D.Double();
Area area1;
Area area2;
public void init() {
setBackground(Color.white);
}
public void paint (Graphics g) {
Graphics2D g2 = (Graphics2D) g;
rect.setFrame(150, 150, 150, 100);
area1 = new Area(rect);
oval.setFrame(100, 100, 150, 100);
area2 = new Area(oval);
area1.intersect(area2);
g2.fill(area1);
}
public static void main(String s[]) {
JFrame f = new JFrame("Intersect Area");
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e)
{System.exit(0);}
});
JApplet applet = new IntersectAreaExample();
f.getContentPane().add("Center", applet);
applet.init();
f.pack();
f.setSize(new Dimension(350,300));
f.show();
}
}
