How do I make a filename URL?

[Steven Davidson]

I want to play an AudioClip and the static method Applet.newAudioClip requires a URL. I am stumped as how to make a URL that represents a file on my computer. The API docs are not very usefull. Thanks.

A code like this should work i guess
File f = new File("mysound.au");
AudioClip theSound;
try {
theSound = Applet.newAudioClip(f.toURL());
} catch (java.net.MalformedURLException e) {
theSound = null;
}
if (theSound != null) {
theSound.play();
}
