Vehicle regisstration Java program. Task is to write a program to registers information about vehicles, and should be buildt according to:

Write an abstract class Vehicle with the following properties:

- private String colour, name, serialNumber.

- private int model (rs modell), price, direction.

- private double speed.

- protected java.util.Scanner input.

- An empty constructor.

- A constructor to initialize all variables ( except for speed, (should be 0)).

- public void setAllFields() method which uses user-input to read in all values from user and put them in object(except from direction and speed,which shoul be 0))

- public abstract void turnLeft(int degrees).

- public abstract void turnRight(int degrees). Both abstract methods should implemented by subclasses.

- get and set methods for all members.

- public String toString() method to print information on all members of the class.

Car inherits from Vehicle

- private int power (hp).

- private Calendar productionDate.

- An empty constructor.

- A constructor to initialize all variables ( except for speed, (should be 0)).

- Override av setAllFields method to also initialize members in Car class.

- turnRight(int degrees) method should first check if 0

- turnLeft(int degrees) should do the same, in opposite direction.

- get and set methods for all members

- Override toString() method to print additional relevant information from Car class.

Bicycle inherits from Vehicle.

- private int gears.

- private Calendar productionDate.

- An empty constructor.

- A constructoor to initialize all variables( except fro speed(should be 0)).

- Override of setAllFields method to also inititialize members of Bicicle class.

- turnRight(int degrees) method should print the amount of degrees turned( no check needed)

- turnLeft(int degrees) should do the same, in opposite direction.

- get and set methods for all members.

- Override toString() method to print additional relevant info from Bicycle class.

TestVehicles should implement all functions marked as TODO.

The TestVehicles code is partly written and is found below :

import java.util.*; /** * Class that tests functionality of Vehicle, Bicycle and Car classes. */ public class TestVehicles { ArrayListVehicle> vehicles = new ArrayListVehicle>(); public static void main(String[] args) { TestVehicles vtest = new TestVehicles(); try { vtest.menuLoop(); } catch (InputMismatchException e) { System.out.println("InputMismatchException!"); System.out.println(e.getMessage()); System.exit(1); } } private void menuLoop() throws InputMismatchException { Scanner input = new Scanner(System.in); Vehicle vehicle; vehicles.add(new Car("Volvo 740", "blue", 85000, 1985, "1010-11", 0, 120)); vehicles.add(new Car("Ferrari Testarossa", "red", 1200000, 1996, "A112", 0, 350)); vehicles.add(new Bicycle("Monark 1", "yellow", 4000, 1993, "BC100", 0, 10)); vehicles.add(new Bicycle("DBS 2", "pink", 5000, 1994, "42", 0, 10)); while (true) { System.out.println("1...................................New car"); System.out.println("2...............................New bicycle"); System.out.println("3......................Find vehicle by name"); System.out.println("4..............Show data about all vehicles"); System.out.println("5.......Change direction of a given vehicle"); System.out.println("6..............................Exit program"); System.out.print(".............................Your choice? "); int choice = input.nextInt(); switch (choice) { case 1: System.out.println("Input car data:"); vehicle = new Car(); vehicle.setAllFields(); // TODO Override method vehicles.add(vehicle); break; case 2: System.out.println("Input bicycle data:"); vehicle = new Bicycle(); vehicle.setAllFields(); // TODO Override method vehicles.add(vehicle); break; case 3: // TODO ask for vehicle name and print out vehicle with that name break; case 4: // TODO list all vehicles break; case 5: // TODO ask for vehicle name and change its direction break; case 6: input.close(); System.exit(0); default: System.out.println("Invalid option!"); } } } }
