Java Programming II - 2015: Exercise Java Basic Review

Submission Guide:
- Due Date: Before the next week's exercise class (April 16, 2015).
- Create a directory ~/java2/ex-review1/ and do a command "chmod 705 ~/java2/ex-review1", and save your answers to the directory.

In this exercise, you will review what you have learned in the Java Programming 1 class. You will design an abstract class and its subclasses to exercise Java polymorphism.

[Question] Designing Vehicle class and Its Subclasses

There are several Vehicles for transportation such as Car, MiniVan, and Truck. Details of the classes for the vehicles are shown in the Figure 1.

Request of the question:
Write Java program code to realize the Figure 1 to show the running result below referring to the template of main method.

Description of the fields and methods of the classes as follows:

1. For Fields

modelName: Model name of a vehicle
company: Company to produce the model
owner: Owner of the vehicle
engineType: Type of the engine. Classified by fuel type to be used such as gasoline, diesel, or hybrid
tankSize: Size of fuel tank. Unit is liter.
fuelConsumption: Fuel consumption. Unit is km/liter.
numberOfSeats: Integer number of seats in a vehicle.
airConditionOn: Boolean status of aircondition's working: ON/OFF.
hasAutoDoor: Boolean status of a vehicle's having auto door.
power: Horse Power of a vehicles's engine.

2. For Methods

movableDistance(): Getting information of movable distance of a vehicle when the tank of the vehicle is filled fully.
costFor100Km(PetroleumPrice): Calculating cost for running 100Kms with the engine type and the petroleum price passed by as parameter. It will be different according to fuel and aircondition's status.
setAirConditionON: Setting the aircondition of the vehicle to ON.
You can guess other methods.

3. Some conditions to write methods

The Car uses only gasoline engine.
The MiniVan can use engine of both gasoline and diesel. But the fuel consumption is same for both gasoline and diesel.
The Truck uses only diesel engine.
The engine type "Hybrid" uses only gasoline.
Default aircondition status is OFF, and the aircondition can be ON/OFF after instances being created by setAirConON/setAirConOFF methods.
Defualt fuel consumption is when aircondition is OFF.
Fuel consumption of the Car decreases by 90% when aircondition of the Car is ON.
Fuel consumption of the MiniVan and the Truck decreases by 80% when aircondition of the Car is ON.
For Petroleum Price: Gasoline(143 yen/liter), Diesel(99.4 yen/liter)

Figure 1. Classes for Question

Template of main method of the class "VehicleTest" is as follows:

---------------------------------------------------------

public class VehicleTest {

    public static void describe(Vehicle v) {
        System.out.println(v);
    }

    public static void main(String[] args) {
        Vehicle vehicles[] = {
        new Car("Camley", "Toyota", "Suzuki", "Gasoline", 70., 15.15, 5),
        new Car("Aqua", "Toyota", "Nakajima", "Hybrid", 36., 40.0, 5),
        new MiniVan("Sienna", "Toyota", "Tanaka", "Gasoline", 75., 9.0, 8, true),
        new MiniVan("Odyssey", "Honda", "Kikuchi", "Diesel", 56., 11.0, 8, false),
        new MiniVan("Presage", "Nissan", "Shirotora", "Gasoline", 60., 7.0, 7, false),
        new Truck("Tundra", "Toyota", "Sugai", "Diesel", 100., 6.76, 5, 310),
        new Truck("Ridgeline", "Honda", "Watanabe", "Diesel", 83.279, 7.23, 5, 250)
            };

        PetroleumPrice priceInfo = new PetroleumPrice(143., 99.4);

        for(Vehicle v: vehicles) {
                  describe(v);
        System.out.println("Movable distance: " + v.movableDistance() + " Km");
        System.out.println("Cost for 100 Km: " + v.costFor100Km(priceInfo) + " Yen");
        System.out.println();
         }
        System.out.println();
        System.out.println("After Aircondition is ON\n");
        for(Vehicle v: vehicles) {
        v.setAirConON();
                  describe(v);
        System.out.println("Movable distance: " + v.movableDistance() + " Km");
        System.out.println("Cost for 100 Km: " + v.costFor100Km(priceInfo) + " Yen");
            System.out.println();
         }

    } // end of main
}
