java.applet.Applet class contains two methods
which download a sound file from a particular URL and play it.
public void play(URL soundfile)
public void play(URL directory, String filename)
For example, the music you're hearing about now is produced by the following applet:
import java.applet.*;
public class SoundApplet extends Applet {
public void init() {
String soundfile = this.getParameter("soundfile");
if (soundfile != null) this.play(this.getDocumentBase(), soundfile);
}
}
