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 Battery Tax: $” + this.batteryDepreciationRate + “/mi”; } }
