-

i'm trying read url below appears work when try store in arraylist gives me error. ideas on whats causing error?

public abstract class itemlist implements itemlistinterface{  private static string inputline; private static arraylist<string> wordarray;  public static void main(string[] args) throws exception {     url wordlist = new url("http://dl.dropbox.com/u/18678304/2011/bsc2/phrases.txt");     bufferedreader in = new bufferedreader(             new inputstreamreader(                     wordlist.openstream()));        while ((inputline = in.readline()) != null){         system.out.println(inputline);         wordarray.add(inputline);     }     in.close();    }  }

you forget instantiate arraylist<string>.
