Scheduling task execution in defined intervalls

[Gabriel Beres]

Hi,

I would like to schedule task execution in bit complicated way.

I want to split a day into intervals, and define the periods of the task execution within these time intervalls.

For example:

8:00am to 13:00pm = 5000 (milliseconds)
13:00pm to 21:00pm = 3000

So, between the first period i want periodic task execution in 5 seconds, and for the latter 3 seconds.

Are there some scheduling framework which supports this, or shall i implement it with Timer?
If only the latter is possible any hint would be nice.

Thanks

Check if Quartz scheduler framework's cron-like trigger expressions do what you want - see the examples at the bottom of the page. 2 expressions - one for 5 second tasks and one for 3 second tasks - will probably be enough.

Try if This might help. This is using Timer and TimerTask. Currently i'm using threads for tasks.
You can change accordingly.

[color=brown]import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;

class MyTimerTask extends TimerTask {
  public void run() {
	  System.out.println("Timer task with Date.");
  }
}

public class time1{
	public static void main(String[] args){
		MyTimerTask myTask = new MyTimerTask();
		Timer myTimer = new Timer();
	    Date date = new Date();

	    /*
	     * Set as today's Date, then repeat every 10 seconds(present in milliseconds, to be converted accordingly).
	     */
	    myTimer.schedule(myTask, date, 10000);

	    try {
	      Thread.sleep(50000);//Sleep after 50 seconds
	    } catch (InterruptedException exc) {
	    }
	    myTimer.cancel();
	}

You can also look at ScheduledExecutorService class.

Quartz is always a better option.you will have lot of options to scedule a job.

I disagree. Just because it has more options does not mean it is the better choice for all situations. It also has higher overhead for settings things up, making its use questionable if the extra options aren't needed.

Ya I do accept. I should have not used the word "always"
