Explanation / Answer

Here is the soluion:

import java.net.*;
import java.io.*;
public class MessageServer
{
   public static final int PORT = 6100;
   public static void main(String[] args) {
       Socket client = null;
       ServerSocket sock = null;
       BufferedReader reader = null;
       try {
           sock = new ServerSocket(PORT);
           /* After creating an object of ServerSocket, here we are using a while-loop and bufferedReader for reading every inputs from clients and storing in an object of MessageImpl class   */
           while (true) {
               client = sock.accept();
               reader = new BufferedReader(new InputStreamReader(client.getInputStream()));
               Message message = new MessageImpl(reader.readLine());
               /* Setting the number of characters and digits in the message */
               message.setCounts();
               /* Converting the java object to stream and writing it in the socket*/
ObjectOutputStream soos = new ObjectOutputStream(client.getOutputStream());
               soos.writeObject(message);
               System.out.println("wrote message to the socket");
               client.close();
           }
       }
       catch (IOException ioe) {
               System.err.println(ioe);
       }
   }
}
