public class TicktimeRefresh extends Thread {
  public TicktimeRefresh() {

  public void run()
  {
    while(true)
    {
      for (int i = 0; i < WholeChatRoomInfo.ticks.size(); i++) {
        TickInfo tInfo = new TickInfo();
        tInfo = (TickInfo) WholeChatRoomInfo.ticks.elementAt(i);
        Date current = new Date();
        if (tInfo.Ticktime.before(current)) {
          WholeChatRoomInfo.ticks.remove(i);
          i--;
        }
      }
      try {
        sleep(6000);
      }
      catch (Exception e) {
