Question
Task 2: Vehicles and Stations Now we want to test our docking interface, but first we want to define an abstract class for our vehicles from which we will model all of our designs after. Instructions 1. Create an abstract class called Vehicle that has the following properties: . a private attribute called name of type String a protected attribute called chargeRemaining of type double • a protected attribute called maxChargeCapacity of type double appropriate getters/setters for the attributes. ● an abstract method called print Info an abstract method called calculateTotalCharge Needed that re- turns a double 2. Create a class called ChargingStation that uses the Dockable interface 3. Make sure that the ChargingStation class has the following properties: . a private array of Vehicle objects that represents the docked vehicles - The index of each object represents its docking number/bay 4. Implement all of the necessary methods in ChargingStation • canDock returns true if there is space for a vehicle to dock or false if the docking array is full dock must take a Vehicle as a parameter and add it to the array of docked vehicles: - if the vehicle is added to the array, return the index (charging port number) of the vehicle 1 . ● - if the vehicle cannot be added to the array return -1 calculateTotalCharge Needed must return the charge needed of the all of the docked vehicles - if the ChargingStation has one vehicle docked that has a maxi- mum charge capacity of 500 kAH with a chargeRemaining of 200 kAH then calculateTotalCharge Needed should return 300 - if the Charging Station has two vehicles docked that both have a maximum charge capacity of 500 kAH with a chargeRemaining of 100 kAH then calculateTotal Charge Needed should return 800 • print Info must print out the name of the ChargingStation and a list of the docked vehicles (see sample output) - if no vehicles are docked then it should print none 5. Create a subclass of Vehicle called Test Vehicle that implements the abstract methods of the Vehicle class: • print Info should print out the name and weight of the Test Vehicle • calculateTotalCharge Needed should return the maxCharge Capacity less the chargeRemaining of the Test Vehicle Hint: the docking array may be partially filled.
