Write an abstract class carrental.Vehicle.
A carrental.Vehicle has an instance variable to store the color of the carrental.Vehicle.
The color can be retrieved with the getColor() method.
The toString() method returns a String like This vehicle is red, depending on the actual color.
Write a class Car that extends the class carrental.Vehicle.
A car has an instance variable of type boolean to define whether it has winter tires or not (default value: false).
The method toString() of the class Car prints the same message as the method of the class carrental.Vehicle, but it does also add another line with the content:
has winter tires: true/false, depending on the actual value.
Write a class Truck that extends the class carrental.Vehicle.
A truck has an instance variable of type boolean to define whether it has a trailer or not (default value: false).
The method toString() of the class Truck prints the same message as the method of the class carrental.Vehicle, but it does also add another line with the content:
has trailer: true/false, depending on the actual value.
Write a class Garage that has a carrental.Vehicle as an instance variable.
This garage can be used by Cars and Trucks.
Define a method setVehicle(carrental.Vehicle parked) to park a vehicle in the garage.
Provide a method toString() to print a message Description of the parked vehicle ...
followed by the description vehicle that is in the garage at this moment.
If there is no vehicle in the garage, "Garage is empty." should be output.
Write a class GarageTester with a method getExample() (see template). In this method, create an object of the Truck class (color is black, and the truck has no trailer).
Create an object of the Garage class. Put the Truck into the Garage.
Write a class Customer that contains a name and an address of a customer.
Define a class CarRentalContract that contains a Customer and a carrental.Vehicle.
We assume that one customer can only rent one vehicle at a time.
This class contains the customer and the vehicle he has currently rented.
CarRental has a method toString() that returns a String containing the name of the customer and the description of the vehicle, in the following format:
- customername[customeraddress]:vehicledescription
Example:
jim jones[Biel/Bienne]:This vehicle is red, has WinterTires: false
Write a class CarRental that contains an array of CarRentalContracts.
This array contains all the currently issued contracts.
The CarRental class provides a method to add new contracts (void addContract(CarRentalContract c1)) to the array and a method (String displayContracts()) that returns all the current rental contracts (by using the toString() method of the CarRentalContract class), each contract on a new line.
Think about the relations between the classes you wrote in this exercise. What is relationship between Garage and CarRental, if any? (You only have to submit the code, not the answer to this question).
