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);
    }
