java - Can ScheduledThreadPool be use to accept different type of threads? -

working on problem have 3 cash counters serving number of customers. every counter take 1 sec process 1 item apart third counter takes 2 sec process each item. (e.g. customer 5 items on counter 1 take 5 seconds complete), customer b 3 items on counter c take 6 seconds. every customer has different time of joining queue. used scheduledexecutorservice create number of threads equivalent cash counters.

scheduledexecutorservice scheduledexecutorservice =executors.newscheduledthreadpool(3); 

now runnable implementation checks number of items , runs loops accordingly.

i submitting number of task depending on number of customer.

scheduledexecutorservice.schedule(new runnable(),timetojoin, timeunit.seconds); 

how assign different priorities 3 threads created executor service. last counter(thread) takes 2 second process each item.

you have provide custom threadfactory executorservice. threadfactory allow create new threads suit needs.

scheduledthreadpoolexecutor(int corepoolsize, threadfactory threadfactory)
