Applets - An Introduction to Network Programming with Java - page 359

Example
The applet below attempts to load an image (from the associated Web page's folder)
into an ImageIcon and then use the ImageIcon 's paintIcon method to display the
image on the applet window.
import java.awt.*;
import javax.swing.*;
import java.net.*;
public class ImageTest2a extends JApplet
{
private ImageIcon image;
public void init()
{
image =
new ImageIcon(getDocumentBase(), " earth.gif");
}
public void paint(Graphics g)
{
image.paintIcon(this,g,0,0);
}
}
Surprisingly, the above applet produces an empty display in the appletviewer and
in IE9! Chrome is also empty of any image, but shows a grey rectangle in the top
left corner, where the applet output would be, as shown in Fig. 12.12 .
