Answer 1

The class java.util.Timer has exactly what you need:

First, set-up the task to be scheduled:

TimerTask task = new TimerTask() {

  void run() {
    //do the task
  }

};

Second, schedule the task:

Date futureDate = ...///whenever you want
Timer timer = new Timer();
timer.schedule(task, futureDate); 

Answer 2

Compute the delay between now and your target date, and call schedule() with this delay as argument:

Date targetDate = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss").parse(dateAsString);
long delayInMillis = targetDate - System.currentTimeMillis();
scheduler.schedule(task, delayInMillis, TimeUnit.MILLISECONDS);
