please solve this using the code given on the bottom. please show the output and the previous question has also been added for reference

Code:

public class BankSimulation{ private final List queue; private int totalWaitingTime; BankSimulation() { queue = new ArrayList(); totalWaitingTime = 0; } public void runSimulation() throws FileNotFoundException { final Scanner filereader = new Scanner(new File("input.txt")); int previousDepartureTime = 0; // until there is input while (filereader.hasNext()) { final Event arrivalEvent = new Event(filereader.nextInt(), "arrival"); final int processingTime = filereader.nextInt(); int departureTime = 0; if (arrivalEvent.getTime() > previousDepartureTime) {// immediate processing departureTime = arrivalEvent.getTime() + processingTime; } else { // wait to get processed departureTime = previousDepartureTime + processingTime; } previousDepartureTime = departureTime; totalWaitingTime = totalWaitingTime + departureTime - arrivalEvent.getTime() - processingTime; final Event departureEvent = new Event(departureTime, "departure"); queue.add(arrivalEvent); // add the arrival and departure events to queue. queue.add(departureEvent); } filereader.close(); Collections.sort(queue, new ListComparator()); } public void printResults() { System.out.println("---Simulation Begins---"); for (final Event event : queue) { if (event.getType().equals("arrival")) { System.out.println("Processing an arrival event at time: " + event.getTime()); }else { System.out.println("Processing a deparature event at time: " + event.getTime()); } } System.out.println("---End of Simulation---"); System.out.println("Final Statistics: "); System.out.println("Total number of people processed: " + queue.size() / 2); System.out.println("Average amount of time spent waiting: " + (float) totalWaitingTime / (queue.size() / 2)); } public static void main(String[] args) throws FileNotFoundException { final BankSimulation bankSimulation = new BankSimulation(); bankSimulation.runSimulation(); bankSimulation.printResults(); } }

The bank is considering the following change: Instead of having three distinct lines (one for each teller), there will be a single line for the three tellers. The person at the front of the line will go t the first available teller. Modify the simulation of Part c to account for this variation. Run both simulations on several sets of input data. How do the various statistics compare (averages and maximums)? What can you conclude about having a single line as opposed to having distinct lines? a
