This is my favourite, here are two solutions for the task
"Write a threaded server that offers the time"
(Ruby example is taken from the book 'The Ruby Way'):


# Ruby
require "socket"

server = TCPServer.new(12345)

while (session = server.accept)
   Thread.new(session) do |my_session|
     my_session.puts Time.new
     my_session.close
   end
end




// And the functional equivalent in Java:
package at.martinus;

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.Date;

public class TimeServer {
   private static class TellTime extends Thread {
     private Socket soc;

     public TellTime(Socket soc) {
       super();
       this.soc = soc;
     }

     public void run() {
       try {
         this.soc.getOutputStream().write(new Date().toString().getBytes());
       } catch (Exception e) {
       } finally {
         try {
           this.soc.close();
         } catch (IOException e1) {
         }
       }
     }
   }

   public static void main(String args[]) throws Exception {
     ServerSocket server = new ServerSocket(12345);
     while (true) {
       new TellTime(server.accept()).start();
     }
   }
}
