Exercise-17: Consider the single server-single queue system that we have discussed. Make necessary changes in the class definitions for the following policy modifications: When selecting a job from the queue select the last job added to the queue. When selecting a job from the queue select the job with largest processing time. Let's suppose that we want to add multiple queues to the system and represent the multiple number of queues with an ArrayList collection in Simulation Manager class. Make necessary changes such that when a job is going to be added to a queue select the queue with least jobs and when a job is going to be selected from a queue select the first job in the most crowded queue.
