Has anybody written a Java program to get Source code from a URL ?

Question

Hi,
I have a program written in another language (Not Java) to basically
pull in the source HTM or HTML code, given a URL.
ex. getsource www.any.com output
So, ==> output will contain the source HTM or HTML code of
www.any.com.
Is there a Java program that do the same ? Like to see it.
Please append here, or provide pointer to get it.
Thanks,.... -- gte99te

Here's a quick program that does just that.
I'd suggest taking a look at the Java Tutorial, at it's section on using URLs descibes how to do this, and it shouldn't tank more than 45 minutes to get through.
import java.io.*;
import java.net.*;
public class SavePage{
    public static void main(String[] args) throws Exception
     // make sure we've been given a URL
     if (args.length != 2)
         System.err.println("Usage: java SavePic <URL> <filename>");
         System.exit(1);
     // convert the string argument to a URL
     URL url = new URL(args[0]);
     // open a connection to the resource with the given URL
     URLConnection connection = url.openConnection();
     // get an input stream from the connection, and wrap it in a buffer
     BufferedInputStream bis = new BufferedInputStream(connection.getInputStream());
     // open an output file and get an output stream to it
     FileOutputStream file = new FileOutputStream(new File(args[1]));
     // wrap[ the file's output stream in a buffer
     BufferedOutputStream bos = new BufferedOutputStream(file);
     // read each byte from tne connection, and write it to the file     int b;
     while( (b = bis.read()) != -1 )
         bos.write(b);
     // clean up
     bis.close();
     bos.close();
}
