Error in Applets

[jayalath.tharaka]

I downloaded the example applet on this page:

http://download.oracle.com/javase/tutorial/uiswing/components/applet.html

I tried to compile TumbleItem.java I got the following:

symbol : class SwingWorker
location: package javax.swing
import javax.swing.SwingWorker;

I have the latest installed java update for MAC so IDK whats going
on.
Thats what my friend got but I got a runtime following error -

java.lang.NoSuchMethodError: main
Exception in thread "main"
Process completed.

all are updated by the latest versions and I am using Windows XP.

The easiest solution is to upgrade your JDK. See

If you download the full example, you'll find TumbleItem.html, which
you should open in your browser after compiling TumbleItem.java.
