hi all, been tryin to find wat is wrong with this code. It works for sometime then starts repeating the same value continuossssssly. any help will be appreciated. thanks

```
/* THIS PROGRAM IS TO RUN A SIMULATION PROGRAM OF ARRIVAL AND SERVICE TIMES OF AN AUTO-REPAIR WORKSHOP
* servTime = serviceTime, depTime = departureTime, arrTime = arrivalTime.
* **/
package home;

depTime = (int) (arrTime+ Math.round(servTime)); //departure time = arrival +service
depTimes.add(depTime);
}
//this is to arrange in ascending order
if (arrTime <= min(depTimes)){

}else {simClock = min(depTimes);
createEvent = false;
for (int i=0; i<depTimes.size(); i++){

}
}
System.out.printf("%d\n",simClock);
}
