public class CustomTimerTask extends TimerTask {

	public Date setDate = null;

	public CustomTimerTask() {

	}

	public CustomTimerTask(Date setDate) {
		this.setDate = setDate;
	}

	@Override
	public void run() {
		if (setDate != null) {
			Date date = new Date(System.currentTimeMillis());

			if (date.toLocaleString().equals(setDate.toLocaleString())) {
				System.out.println(date.toLocaleString());
			}
		}
	}

}

public class StartTask {
	
	public static void main(String[] args){
		SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		Timer timer=new Timer();
		//第一个任务的时间
		Date setDate=format.parse("2012-7-10 15:51:05");
		timer.schedule(new CustomTimerTask(setDate),setDate);
		//第二个任务的时间
		setDate=format.parse("2012-7-10 15:51:25");
