why no one is not helping?Pls guys help meDon't say things like that.
It looks like your URL is wrong. Basically you are trying to construct a URL in a bit of a dodgy way. Why don't you just create a File object that corresponds to the audio file (clue: you don't need to give it a full path, as it looks like the file is in the same relative path as the class anyway, due to your use of '.'), by just giving it the filename, then do File.toURL() to get the URL, and pass this in to Applet.play(). Your code would be far simpler, and hey might even work. Read the APIs.
