You can't get the code, an applet is compiled. And from the names in the code there, I'm guessing it has something to do with
fourier

That's correct. It is related to
Fourier
Transforms. Well, I'm not interested in the code. I'm interested in the applet itself. Then, is there any way I can save it in my computer?
