java - Create SWT browser exception -


how create exception seturl() method swt browser ? want show url wrong or problem connectivity.

it seems want check if given url available/reachable. in case, code want:

private static boolean isreachable(string url) {     try     {         httpurlconnection connection = (httpurlconnection) new url(url).openconnection();         connection.setrequestmethod("head");         int responsecode = connection.getresponsecode();          return responsecode == 200;     }     catch (ioexception e)     {         return false;     } }

just call before call browser#seturl().
