I see what you mean....each time its just going to print the current line, instead of appending it to the end.

I've tried to move the file/Output stuff outside the while but that doesn't work.

I tried this
Code:
import java.io.*;
import java.net.*;

public class scrapeSite
{
    public static FileOutputStream Output;
    public static PrintStream file;
    public static String line;

   public static void main( String[] args )
   {
      try
      {
         BufferedReader br;
         BufferedWriter bw;

         // create a connection to 'www.yahoo.com' on port 80
         Socket s = new Socket( "www.yahoo.com", 80 );

         // create the reader and writer objects
         br = new BufferedReader( new InputStreamReader( s.getInputStream() ));
         bw = new BufferedWriter( new OutputStreamWriter( s.getOutputStream() ));

         // request the 'root' page
         bw.write( "GET / HTTP/1.0\n\n" );
         bw.flush();

         // while more lines, output to the standard output stream
         while( (line = br.readLine()) != null )
         {
            Output = new FileOutputStream("myfile.txt");
         }
      }
      catch( IOException e )  // catch any errors
      {
         System.out.println( "There was an IOException error!" );
      }
      file = new PrintStream(Output);
      file.println(line);
   }
}
but that doesn't work either. It runs but give NullPointerExceptions and it prints null in myfile.txt

I don't know how to break out of the loop, or move the code out of the loop
I'm looking at these sites (1,2) but I cant get this thing to run.
Any more hints?
