        </dependency>
_______________________________

Make Two Classes : 1. HelloJob.java 2. SimpleTriggerExample.java

1. Hello.java
__________________________
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class HelloJob implements Job
{
    public void execute(JobExecutionContext context)
    throws JobExecutionException {

        System.out.println("Hello Quartz!");   

    }

}
______________________________
2. SimpleTriggerExample.java
______________________________
import java.util.Date;

import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SimpleTrigger;
import org.quartz.impl.StdSchedulerFactory;

public class SimpleTriggerExample
{
    public static void main( String[] args ) throws Exception
    {
           JobDetail job = new JobDetail();
        job.setName("dummyJobName");
        job.setJobClass(HelloJob.class);

        //configure the scheduler time
        SimpleTrigger trigger = new SimpleTrigger();
        trigger.setName("mytrigger");
        trigger.setStartTime(new Date(System.currentTimeMillis() + 1000));
        trigger.setRepeatCount(SimpleTrigger.REPEAT_INDEFINITELY);
        trigger.setRepeatInterval(3000);

        //schedule it
        Scheduler scheduler = new StdSchedulerFactory().getScheduler();
        scheduler.start();
        scheduler.scheduleJob(job, trigger);
    }
}
______________
save both and Run SimpleTriggerExample
it will repeat the job at interval of 3 second.
