java.util.Timer.schedule()
Schedules the specified task for execution after the specified delay. @param task task to be scheduled. @param delay delay in milliseconds before task is to be executed. @throws IllegalArgumentException if delay is negative, ordelay + System.currentTimeMillis() is negative. @throws IllegalStateException if task was already scheduled orcancelled, or timer was cancelled.
