Well. Applet cannot write or read from files, so you have to write another so called middle-ware program, that serves datas.
He sends to applet last high score and if player scores new high score, then send this data back to program, which stores it in the file.
This program is standalone application, which watch specific port for connections. Applet can connect to this program, because applets can connect to computer, from which they were loaded from. So program must run on web machine.
I will give you an example how to make a client, how to make a server is much easier.
 import java.io.*;
import java.net.*;

public  class SocketClient
{
  Socket socket;
  DataInputStream in;
  PrintStream out;
  boolean connected = false ;
 
  public SocketClient( String host, int port) throws IOException
  {
    socket = new Socket(host, port);
    in = new DataInputStream(socket.getInputStream());
    out = new PrintStream (socket.getOutputStream());
    connected = true ;
}

  public void write(String data)
  {
    out.println(data);
 }

  public String read() throws IOException
  {
    return in.readLine();
  }
 
  public void disconnect ()
     {
        if ( connected )
          {
             try
               {
                  in.close();
                  out.close();
               } catch (IOException e) { }
             if ( socket != null )
               {
                  try {socket.close();
                  }
                  catch (Exception e) { }
               }
          }
       in = null;
        out = null;
        socket = null;
        connected = false;
     }
 
 public boolean isConnected () { return connected;}



}
*********************************************
Use it in you code like this:
 try
   {    
    client = new SocketClient("name.of.the.machine",41234);
   }
            catch (IOException e )
if (client != null )
   {
     if ( client.isConnected())
       {
        //lets write something to server
      client.write("HELLO");
       //lets read lines until server closes connection
        while ( ( line = client.get_line()) != null)
                      {
                        System.out.println("GOT : "+line);
                      }
        //lets disconnect
        client.disconnect();

Hope this is the answer ?
