The class java.net.URL has methods to create and manipulate URL objects:
String urlStr = "http://www.npac.syr.edu/";
try {
  • URL url = new URL( urlStr );
} catch ( MalformedURLException e ) {
  • System.err.println( "Bad URL: " + urlStr );
}
The document at this URL may be displayed in the current browser window with:
getAppletContext().showDocument( url );
Another version of showDocument(...) permits the document to be loaded into an arbitrary HTML frame.
