    I am currently writing a Java application (not an applet). To load a particular file (from the local hard disk), I need to have it represented as a URL class object. If I know my file to be: "C:\JavaWork\Sounds\mysound.au", how do I turn this into a URL?

I am not sure how to tell the URL constructor that this is a local file and how to represent the path and file name to the URL constructor so it is found.

Generally you don't have to represent a file as an URL just to open it from a local disk from within an application (FileInputStream should do).

To create an URL object you can use several methods:
new URL("file:///C|/JavaWork/Sounds/mysound.au");
or
new URL("file", "", "C:\JavaWork\Sounds\mysound.au");

Protocol "file" is supported by JDK (along with such protocols as doc, http, gopher, ftp, mailto). That means that after constructing an URL object with file protocol you can open an URLConnection to that object (from which in turn you can get an input or output stream for the underlying resource).

myFile = new URL("file:///C|/JavaWork/Sounds/mysound.au");
URLConnection uc = myFile.openConnection();
InputStream fileInputStream = uc.getInputStream();

Check the URLConnection class, it has plenty of useful method to work with your resource.
