练习使用数据结构中的Queue，模拟一个银行的排队场景。 ObjectiveCreate and use queues InstructionsDevelop a java program that simulates the queues in a bank. Bank Queue Simulation ProblemImplement the event-driven simulation of a bank that this chapter described on pages 434 through 444. A queue of arrival events will represent the line of customers in the bank. Maintain the arrival events and departure events in an ADT event list, sorted by the time of the event. Your program must count the customers and keep track of their cumulative waiting time. These statistics are sufficient to compute the average waiting time after the last event has been processed. Display a trace of the events executed and a summary of the computed statistics (total number of arrivals and average time spent waiting in line). InputIn this section, the various input tables are described. Customer TableThe Customer Table identifies the Customers coming into the bank, the time they arrive and the transactions they wish to perform. Note that a Cust
omer may want to perform multiple transactions. Transaction Number Customer ID Arrival Time Transaction Type 1 1 1 Transfer 2 1 Deposit 3 2 4 Withdrawal 4 2 Account Balance 5 3 7 Account Balance 6 3 Withdrawal 7 3 Deposit 8 4 8 Withdrawal 9 5 9 Transfer 10 6 13 Transfer Transaction Type TableThe Transaction Type table identifies the duration for the teller to perform each Transaction Type. Transaction Type ID Transaction Type Description Duration 1 Deposit 4 2 Withdrawal 2 3 Transfer 3 4 Account Balance 1 OutputThe table below should be output to show the customers arrival time, the time waiting in line and the time they depart. This information should be used to calculate the total number of arrivals and the average wait time. Customer Arrived Waiting Time At Teller Transaction Time Departed 1 1 0 1 7 8 2 4 4 8 3 11 SubmitSubmit the following: Requirements Test Cases UML diagram for the application Text file(s) containing the classes and methods Text file containing the results
