i have some questions regarding URL class in java.net ,
i have 2 q's
  • by using URL class we can download and upload data via http protocol just like what we do using ftp protocol ?
  • suppose i have a code where i m using URL class to connect to localhost 127.0.0.1 through an http protocol so by default this code will conect to port 80 right ? ,
    but the big question is who will receive the data , if suppose i send some data like string ? i m asking this because using socket and server socket we know with whom we are connected or communicating and the server socket (server ) will receive our data and do some processing
    but who will receive the data in case of URL class ?

  • any explanation ?




    The Only way to learn is ...........do!

    If you create a URL that starts "http" the request will go to a HTTP server living at the specified host and listening at the default port (if you don't specify a port).

    If there is no HTTP server living at that location you will of course get an error.

    It is sorta covered in the JavaRanch Style Guide.
