Using a java.util.Timer class you can create a timer and schedule it to run at specific time.
Below is the example:
//The task which you want to execute
private static class MyTimeTask extends TimerTask
{
public void run()
{
//write your code here
}
}
public static void main(String[] args) {
//the Date and time at which you want to execute
DateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = dateFormatter .parse("2012-07-06 13:05:45");
//Now create the time and schedule it
Timer timer = new Timer();
//Use this if you want to execute it once
timer.schedule(new MyTimeTask(), date);
//Use this if you want to execute it repeatedly
//int period = 10000;//10secs
//timer.schedule(new MyTimeTask(), date, period );
}
