public class newshandler extends defaulthandler {     private string url = "http://tomasinoweb.org/feed/rss";     private boolean indescription = false;      private string[] descs = new string[11];      int = 0;          public void processfeed() {              try {              saxparserfactory factory =               saxparserfactory.newinstance();              saxparser parser = factory.newsaxparser();              xmlreader reader = parser.getxmlreader();              reader.setcontenthandler(this);              inputstream inputstream = new url(url).openstream();               reader.parse(new inputsource(inputstream));               } catch (exception e) { e.printstacktrace(); }         }         public void startelement(string uri, string localname, string qname,              attributes attributes) throws saxexception {             if(qname.equals("description")) indescription = true;          }          public void characters(char ch[], int start, int length) {              string chars = new string(ch).substring(start, start + length);              if(indescription) descs[i] = chars;          }          public void endelement(string uri, string localname, string qname) throws saxexception {             if(qname.equals("description")) {                            indescription = false;                           i++;                      }         }          public string getdesc(int index) { return descs[index]; }          public static void main(string[] args) {             newshandler nh = new newshandler();             nh.processfeed();              for(int i=0; i<10; i++) {                 system.out.println(nh.getdesc(i));             }          } } 

solution:

instead of using string url = "url", used url url = new url("url") , urlconnection con = url.openconnection() , con.addrequestproperty("user-agent", user-agent string);
