SimpleTrigger trigger = (SimpleTrigger) newTrigger()
.withIdentity("trigger1", "group1")
.startAt(myStartTime) // some Date
.forJob("job1", "group1") // identify job with name, group strings
.build();

trigger = newTrigger()
.withIdentity("trigger3", "group1")
.startAt(myTimeToStartFiring) // if a start time is not given (if this line were omitted), "now" is implied
.withSchedule(simpleSchedule()
.withIntervalInSeconds(10)
.withRepeatCount(10)) // note that 10 repeats will give a total of 11 firings
.forJob(myJob) // identify job with handle to its JobDetail itself
.build();

here i want to identify is all the triggers has been completed i.e the 11th one.
How to get details once the last trigger is completed. I need to execute the event after completion.
