import java.net.*;
import java.io.*;

public class MessageClient
{
   public static final int PORT = 6100;
   public static final String host = "127.0.0.1";

   public static void main(String[] args) throws IOException {
       Socket sock = null;
      
       if (args.length != 1) {
           System.err.println("Usage: java MessageClient <message>");
           System.exit(0);
       }
      
       try {
/* Comment Here */
           sock = new Socket(host, PORT);

           PrintWriter pout = new PrintWriter(sock.getOutputStream(),true);

           pout.println(args[0]);

           /* Comment Here */
           ObjectInputStream ois = new ObjectInputStream(sock.getInputStream());

           Message message = (Message) ois.readObject();
           System.out.println(message.getCharacterCount());
           System.out.println(message.getDigitCount());
       }
       catch (IOException ioe) {
           System.err.println(ioe);
       }
       catch (ClassNotFoundException cnfe) {
           System.err.println(cnfe);
       }
finally {
   sock.close();
}
   }
