public class ch7_fig5
extends Applet
A class that prompts the user for a URL, then goes through the, presumably HTML, content of that URL checking for links to other WWW content and making sure that the documents those links connect to actually exist and that all THEIR links are valid. This is recursive and potentially time-wasting.
