Scenario You are designing the tracking module for a global shipping company’s autonomous delivery fleet. The system monitors the operational transit costs of different cargo vehicle types. The architecture includes an abstract base class DeliveryVehicle and a fully implemented subclass DroneDelivery. Your task is to complete the implementation by creating a second subclass, CargoVan, and writing a main method using standard ArrayList methods to demonstrate polymorphism and persistent file logging. Given Code (Do Not Modify) // Abstract Base Class public abstract class DeliveryVehicle { private String vehicleId; private double baseCostPerMile; // Flat standard operating cost public DeliveryVehicle(String vehicleId, double baseCostPerMile) { this.vehicleId = vehicleId; this.baseCostPerMile = baseCostPerMile; } public String getVehicleId() { return vehicleId; } public double getBaseCostPerMile() { return baseCostPerMile; } // Abstract method to calculate total trip cost over a given distance public abstract double calculateTripCost(int miles); } // Completed Subclass: DroneDelivery public class DroneDelivery extends DeliveryVehicle { private double batteryDepreciationRate; // Additional fixed multiplier per mile (e.g., 0.15) public DroneDelivery(String vehicleId, double baseCostPerMile, double batteryDepreciationRate) { super(vehicleId, baseCostPerMile); this.batteryDepreciationRate = batteryDepreciationRate; } @Override public double calculateTripCost(int miles) { // Drones add an extra flat depreciation tax per mile traveled return (getBaseCostPerMile() + this.batteryDepreciationRate) * miles; } @Override public String toString() { return “DroneDelivery [” + getVehicleId() + “] Battery Tax: $” + this.batteryDepreciationRate + “/mi”; } }

Task 2 (12 points): Demonstrate Polymorphism and File Processing in Main I In a separate manager class containing the main method, complete the full execution workflow: Collection Setup: Create a single ArrayList capable of holding both StandardRoom and LuxurySuite objects. Populate it with at least one StandardRoom and at least two LuxurySuite objects (one with the pool heating turned on, one off). File IO Streams: Wrap your processing operations inside a standard try-with-resources block utilizing FileWriter and PrintWriter to write to an output file named room_operating_costs.csv. Table Structure: Write a clear header row to the file first to define the table columns: Room Type,Room Number,Attributes/Status,Stay Duration (Days),Total Operating Cost ($). Index-Based Loop Processing: Use a standard index-based for loop driven entirely by ArrayList methods (like .size() and .get(int index)) to polymorphically process a 7-day booking period across all rooms. Dynamic Row Layout: Inside the loop, extract the room’s simple class name via .getClass().getSimpleName(). Construct and print each line of comma-separated values, ensuring text-heavy attributes (like the toString() result) are completely enclosed in quotes (“…”) within the CSV to guarantee clean data parsing. Expected CSV File Output Format When the generated room_operating_costs.csv file is opened in a plain text editor, its structured rows must look like this: Plaintext Room Type,Room Number,Attributes/Status,Stay Duration (Days),Total Operating Cost ($) StandardRoom,Room_204,”StandardRoom [Room_204] Eco-Tax: $5.50/day”,7,423.50 LuxurySuite,Suite_101,”LuxurySuite [Suite_101] HeatedPool: false”,7,700.00 LuxurySuite,Suite_102,”LuxurySuite [Suite_102] HeatedPool: true”,7,1225.00
