Most of the applications written these days require some or the other network feature. Stand-alone Java applications are rare occurence these days. In order to write a Java program which reads a Webpage, follow the steps mentioned below.

1.) Instantiate a URL object by passing the URL string to its constructor. [Line 16 in the code below]

2.) Retrieve a URLConnection object . [ Line 17 in the code below]

3.) Get an input stream from the connection. [Line 18-20 in the code below]

4.) Create a BufferedReader on the input stream and read from it. [Line 23-25 in the code below]

In the code mentioned below, i have tried reading http://technofriends.in

public class ReadURL {

 public static void main(String[] args) throws Exception {

 URL url = new URL("http://technofriends.in");

 URLConnection tf = url.openConnection();

 BufferedReader in = new BufferedReader(

                                new InputStreamReader(

                                tf.getInputStream()));

 String inputLine;

 while ((inputLine = in.readLine()) != null)

            System.out.println(inputLine);

        in.close();

    }

}
