or can suggset some reference website to me?

I solve my problem la!
it is not the URL object problem,it can point to
a url.
I make a mistake in string.
I use URL.toString().substring(index) to solve.

yes, you are right!
SDK show that "NullPointerException"
I want open a image in a applet  through the
java.net.URL.
Must ues "java.net.URL" ?Can i use other method?
I want use a String to store the URL.
thx!

private java.net.URL texImage;
String str;

----------------------------------
why it is not work ?
