Yоu hаve twо prоgrаmming tаsks following the problem described above: Task 1 (10 points): Create the CargoVan Subclass Write a class named CargoVan that inherits from DeliveryVehicle. It must include: An additional private instance variable: boolean rushHourTrafficActive. A constructor that accepts vehicleId, baseCostPerMile, and sets rushHourTrafficActive using a passed boolean parameter. An overridden calculateTripCost(int miles) method. Rule: If rushHourTrafficActive is true, idling wastes fuel, causing the trip cost to jump by an extra 50%. An overridden toString() method that returns a string format exactly like this: CargoVan [[vehicleId]] RushHour: [true/false] (e.g., CargoVan [Van_Grid4] RushHour: true).
Bаsed оn the fоllоwing definition of the Hаmster clаss, which of the following statements in the below segment of code would you expect to be valid (to NOT produce any Java syntax errors or throw any runtime exceptions)? You may assume that the necessary constructors are implemented. Each statement has an associated comment, which indicates the option corresponding to that statement. Select all valid options. public class Hamster extends Pet implements ThingsPetsDo { .... }public class PetDemo{ public static void main(String[] args) { Object o1 = new Pet(); // 1 ThingsPetsDo t1 = new Hamster(); // 2 Object o2 = new Hamster(); // 3 Hamster h = (Hamster) o1; // 4 Pet p1 = (Pet) o1; // 5 Pet p2 = (Pet) t1; // 6 ThingsPetsDo t2 = new ThingsPetsDo(); // 7 ThingsPetsDo t3 = new Pet(); // 8 }// end of the main method}
