First Time With The URL Class

Question

Okay, I've been exploring the various classes available in Java, in the hope of building a web-indexer (more as an exercise in Java than anything useful). However, I've been snagged fairly early on, in that I can't even call the class constructor...
Here's what I've got so far, for the class (called WebDoc):
import java.net.URL;
public class WebDoc {
    WebDoc( URL myURL) {
        System.out.println("This method works");
}and for the test program:
import WebDoc.*;
public class WebIndexerTest1 {
    public static void main(String[] args) {
        WebDoc myDoc = new WebDoc("http://www.dcs.shef.ac.uk/~martin/test1.htm");
}The WebDoc class has compile successfully, and is in the WebDocClass folder, in the correct place.
At the moment, it throws the error:
WebIndexerTest1.java [5:1] cannot access WebDocClass.WebDoc
bad class file: C:\Documents and Settings\Joseph Lloyd\My Documents\Uni\OOPing\WebIndexer\WebDocClass\WebDoc.class
class file contains wrong class: WebDoc
Please remove or make sure it appears in the correct subdirectory of the classpath.
        WebDoc myDoc = new WebDoc("http://www.dcs.shef.ac.uk/~martin/test1.htm");
        ^
1 errorwhich I assume means it can't find the WebDoc class. I can't see why not though. Can anyone help me out with this? I'm pretty sure it's something fairly obvious, but unfortunately not to me...

Cheers for the input, especially about packages. It's been quite a bit since I last touched Java, and I've forgotten most of the syntax.
After looking over the code, it's now modified to the following, but still throws up the original error that prompted me to start messing about with importing (for some reason). The WebDoc code is identical to before, but the test program has changed:
import java.net.URL;
public class WebIndexerTest1 {
    public static void main(String[] args) {
        String myString = "http://www.dcs.shef.ac.uk/~martin/test1.htm";
        URL myURL = new URL(myString);
        WebDoc myDoc = new WebDoc(myURL);
}However, it still throws the following error, and I have, after perusing the documentation and help files, no idea on how to deal with it (I assume I should have some kind of exception handler there, but I don't see why the URL class is throwing the exception in the first place...):
WebIndexerTest1.java [6:1] unreported exception java.net.MalformedURLException; must be caught or declared to be thrown
        URL myURL = new URL(myString);
                    ^

Errors compiling WebIndexerTest1. Any further help would be greatly appreciated, as this has been winding me up all day, and I apologise in advance if I'm displaying excessive stupidity in not noticing glaring errors...
