        URL url=__________________________________;
        BufferedReader in =_________________________________;
        String inString;     
        File outfile=new File("test.html");      
        PrintWriter out=new PrintWriter(new FileWriter(outfile));
        while ((inString=in.readLine())!=null){ 
               out.println(inString);
        }
        in.close();
