I am working on a simple method that will assign a specific extension

You might try the URI class. Make a URI, get the path, and then just
check that one string for a valid extension. This will be much easier
than trying to parse a URI yourself.
Going forward that is perhaps a really good idea for checking the
validity of a URL, however, what i was trying to do was to check to
see if the URL had an extension and add ".jsp" if it did, otherwise,
add nothing.
What I wound up doing, though, was a lot simpler, by chopping off any
optional query strings and anchors I then checked the newly-created
end of the URL for an extension via Pattern.matches("xxx") and added
".jsp" accordingly.
But the URI class looks interesting as does the URL class. Thanks!
