I need to make a bank simulation where a user enters the number of tellers they want and then for every tick there's a chance that a customer object will be created with a process time and priority time. Customers who have a higher priority time should be helped first when the next teller is available, and the process time determines how many ticks the customer will spend at the teller before the teller can help the next customer. The customers are stored in a MaxHeap. Below is a portion of my output. My terminal is not printing when the customer leaves and so I am not even sure if the customer is being stored in the heap. Tick 10 *************** Tick 11 New customer has arrived with the priority 4 and transaction time: 8 Below is the output I want.
