Getting Information from a Remote Site 

• So once you have a connection to a web server it is likely that the first thing you will want to do is get data. Getting data from a web server is as easy as opening a connection and uses a data stream to handle the flow of data between your application and the server. 
• Typically, you will read in a data file from a given URL using something like the following: 

try
  {
  Socket s = new Socket("www.extropia.com", 
                         80);
  DataInputStream d = new DataInputStream
                      (s.getInputStream());
  String line = d.readLine();
  System.out.println("line: " + line);
  
  System.out.println("" + url.openStream());
  }
catch (IOException e)
  {
  System.out.println("Error: " + e);
  }
