I need a timer to be enabled so if I select "c" set the status as "Cleared for Landing" then = 5 seconds timer the automatically changes status = "Descending" then= 5 seconds then automatically changes auto status = "Landing" = 5 seconds then finally automatically changes to status ="Arrived" this ends select System.out.println("Change Flight Status = c");
if you select "ok" from the menu which is "Cleared for Landing" I was trying to use timer.schedule(new MyTimerTask(),5000); and then the status would automatically change from "Cleared for Landing" to "Descending" and 5 seconds after that the flight status would change to "Landing" and last.. 5 seconds the flight status would change to "Arrived". all using automation with something like the timer.schedule(new MyTimerTask(),5000); . can you help set the flight status?

=========================================================
//public void schedule(TimerTask task, long delay,long period)
-
// it will execute timer task after delay of 5 seconds
// timer.schedule(new MyTimerTask(),5000);
