hi i'm kind of new to java an i want to copy a file between a simple server and a simple client.

I know how to do the client and the server (using Socket class and ServerSocket), but i dont know how to copy a file. I know how to copy a file in my machine with Input Stream and FileInputStream, but i don't know how to use it over the net.

Server

Code:

import java.net.*;
public class server
{
 public static void main(String arg[]) throws IOException
 {
  int port = 8080;
  ServerSocket s = new ServerSocket(port);
 
  try
  {
   Socket socket = s.accept();
   //copy file  code here
 
   socket.close();   
  }
  finally
  {
   s.close();
  }
 }
}

Client

Code:

import java.net.*;
public class client
{
 public static void main(String arg[]) throws IOException
 {
  InetAddress addr = InetAddress.getByName(null);//because i'm in my pc
  Socket socket = new Socket(addr, server.port);
 
  try
  {
 
 
  }
  finally
  {
   socket.close();
  }
 }
}

If you can provide a simple example it will be very helpful

Thanks in advance for your help.
