Answer 1

As I know you can use Quartz-scheduler for this. I have not used it yet, but many people have recommended it to me.

Answer 2

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 );
}

Answer 3

Its is possible, and I would use a library such as http://quartz-scheduler.org/

Quartz is a full-featured, open source job scheduling service that can be integrated with, or used along side virtually any Java EE or Java SE application - from the smallest stand-alone application to the largest e-commerce system. Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs; jobs whose tasks are defined as standard Java components that may execute virtually anything you may program them to do.
