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) Java // 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”; } }

Consider the following code snippet. Select all correct options that can be used as MyType. public static MyType GetMax3 (MyType i, MyType j, MyType k) { // determines max};

Consider a try block with multiple catch blocks. Inside the try block, you have written a segment of code that may cause one of the following three exceptions to be thrown, depending on the circumstances: IOException SocketTimeoutException ConnectException Put the catch blocks  in the correct order in the try block, so that your program can respond differently to each exception. The class hierarchy (parent->child relationship) of these exceptions are as listed in the above order. Please refer to the provided JavaDoc links, for further details.

Which of the following is not a benefit of abstraction in OOP?

  Complete the following SQL to retrieve records for all Product and related records from ProductsBrowsed (where available).  Only include products that with dateIntroduced in the months of Jan, Feb, March of 2020 and belonging to Subcategory that is one of the following: hardware, electronics, appliances  Copy-paste the SQL from below into your answer and complete the remainder to meet the requirements. SELECT  P.*         , PB.* FROM PRODUCT P 

Given the following two tables TABLEA and TABLEB with FKAB as foreign key.  Which of the following SQL choices produces this result table: T1.pkA T1.attra1 T2.pkB T2.attrB1 T2.fkAB 1 A1 A B1 1 1 A1 B B2 1 2 A1 D NULL 2 3 A2 NULL NULL NULL 4 A2 NULL NULL NULL 5 NULL F B3 5 NULL NULL C B1 NULL NULL NULL E B2 NULL

  Assuming that the table AIRPLANES already exists, which of the SQL statements correctly removes all records with manufacturer WRIGHT and model X-WING

   Based on the ER above — CUSTVEH entity is _____________ with respect to VEHICLE entity

  Write SQL query to show UPC_CODE for all Product, number of times the product was browsed, number of times product was ordered, and total quantity for product that has been ordered.   NOTE: each time a product is browsed, it is tracked using unique viewingID  each time a product is ordered, it is identified using unique orderNumber qtyOrdered in OrderedItems tracks the quantity of a product in each order. HINT: Only required tables for the query are — Product, ProductsBrowsed and OrderedItems
