public void schedule(TimerTask task,
                     Date date)

Schedules the task at the specified data for one time execution.

Throws:

IllegalArgumentException - if date.getTime() is negative

IllegalStateException - if the task was already scheduled or canceled or this Timer is canceled or the scheduler thread has died

public void schedule(TimerTask task,
                     Date date,
                     long period)

Throws:

IllegalArgumentException - if period or date.getTime() is negative

IllegalStateException - if the task was already scheduled or canceled or this Timer is canceled or the scheduler thread has died

public void schedule(TimerTask task,
                     long delay)

Schedules the task after the specified delay milliseconds for one time execution.

Throws:

IllegalArgumentException - if delay or System.currentTimeMillis + delay is negative

IllegalStateException - if the task was already scheduled or canceled or this Timer is canceled or the scheduler thread has died

public void schedule(TimerTask task,
                     long delay,
                     long period)

Schedules the task after the delay milliseconds and reschedules the task every period milliseconds after the last execution of the task finishes until this timer or the task is canceled.

Throws:

IllegalArgumentException - if delay or period is negative

IllegalStateException - if the task was already scheduled or canceled or this Timer is canceled or the scheduler thread has died

public void scheduleAtFixedRate(TimerTask task,
                                Date date,
                                long period)

Schedules the task at the specified date and reschedules the task at a fixed rate every period milliseconds until this timer or the task is canceled.

Throws:

IllegalArgumentException - if period or date.getTime() is negative

IllegalStateException - if the task was already scheduled or canceled or this Timer is canceled or the scheduler thread has died

public void scheduleAtFixedRate(TimerTask task,
                                long delay,
                                long period)

Schedules the task after the delay milliseconds and reschedules the task at a fixed rate every period milliseconds until this timer or the task is canceled.

Throws:

IllegalArgumentException - if delay or System.currentTimeMillis + delay is negative

IllegalStateException - if the task was already scheduled or canceled or this Timer is canceled or the scheduler thread has died
