How can i do the server send a message in a particular time?

Question

Hi everyone!
in my program, clients choose a number from 1 to 10 and send it to the server.
server produces a number every 5 min and send the client the result (if they
win or lose) immediately.
i 'd like to convert this, in order the result to be sent from the server to client when the time(5min) is finished - just before a second draw occurs.
so the clients must wait to be notified by the server and disconnected when
the server sends the result.
can anyone help me on how to convert this piece of code to do that task?
// control thread's execution
      public void run()
         int message=0;
         Timer timer = new Timer();
         TimerTask task = new TimerTask(){
            public void run() {               
               rnum=randGen.nextInt(10);
        display.append( "\n"+ "THE MAGIC NUMBER IS: " + rnum );
     timer.scheduleAtFixedRate(task, 100, 30000) ;
// process connection
         try {
            // read message from client
            do {
               try {
                  message =  input.readInt();
                  if (message==rnum){output.writeUTF("SERVER>>> YOU WON: MAGIC NUMBER IS: " +rnum);}
                   else {output.writeUTF("SERVER>>> YOU LOSE: MAGIC NUMBER IS: " +rnum);}
                  display.append( "\n\n" +"PLAYER " + clientNumber + " SELECTED NUMBER " + message );
                  display.setCaretPosition( display.getText().length() );
               // process problems reading from client
               catch ( IOException ioException ) {
                  display.append( "\nUnknown object type received" );
            } while ( message!=-1 ); //temporary

Do you not have a Sent Items folder of some description? 
Search using Spotlight (little magnifying glass in the top right of your screen), that may be able to help.
