Assignment 1
File to Submit:
• TestDealer.java, which contains classes TestDealer, Car, NewCar, UsedCar, CarDealerShip (Note: make sure that only class TestDealer has "public" in front. Do not send multiple files in a ZIP file).
Introduction
In this assignment you will create a stand-alone application for a car dealership.
The dealership deals with two types of cars - new and used cars. Each car has the following common information: model, year made, and price. In addition a new car has information on its color and a used car has information on whether it is rusty. If a used car is rusty, its selling price will be discounted by $800; if it is not rusty its selling price is equal to its price.
Your task
Create three classes: Car, NewCar, and UsedCar, where NewCar and UsedCar inherit Car. The class Car should have the following fields: model, price, and year. The class NewCar should have the String field color; the class UsedCar has the boolean variable rusty. Each class should have a constructor that takes arguments of all its fields. Hence, the class Car should have a constructor Car(String model, int year, int price), class NewCar has the constructor NewCar(String model, int year, int price, String color), and class UsedCar has the constructor UsedCar(String model, int year, int price, boolean rusty). All these classes should have methods toString() which will return a string that displays all the information encapsulated in the class.
Create another class named CarDealerShip, which has the following methods: void addNewCar(String model, int year, int price ,String color);
void addUsedCar(String model, int year, int price, boolean rusty); String printReport();
String printAllCarsWithSellingPriceBelow(int price); String printAllCarsOfColor(String color);
The class CarDealerShip should use an array named "cars" to store all the available cars up to a maximum of 80 cars.
You should use only one array to store all the cars, including used and new cars. The method addNewCar() will instantiate a NewCar object and add it to the array cars while the method addUsedCar() will instantiate a UsedCar object and add it to the same array. The method printReport() will return a string that displays the information of all cars added to the array cars, method printAllCarsWithSellingPriceBelow(int price) will return a string that displays the information of all cars with selling prices below the price argument and method printAllCarsOfColor(String color) will return a string which displays the information of all cars of a color given as argument.
Test program
The following test class is to be entered at the beginning of your file TestDealer.java: public class TestDealer {
public static void main(String[] args) {
CarDealerShip dealer = new CarDealerShip(); dealer.addNewCar("GM Buick Century", 2004, 20000,"Silver"); dealer.addUsedCar("Toyota Corolla", 1999, 9000, true);
dealer.addNewCar("Honda Civic", 2004, 15000, "Green");
dealer.addNewCar("BMW 320i", 2004, 35000, "Black");
dealer.addUsedCar("Toyota Sienna", 2000, 11000, false);
System.out.println(dealer.printReport()); System.out.println("****************************************");
System.out.println(dealer.printAllCarsWithSellingPriceBelow(10000)); System.out.println("****************************************"); System.out.println(dealer.printAllCarsOfColor("Green");
}
}
In the same file, below class TestDealer add classes CarDealerShip, Car, NewCar and UsedCar, which you have created.
The correct output of TestDealer should be: Car 1: New car
Model: GM Buick Century Year Made: 2004
Price: 20000 Color: Silver
Selling Price: 20000
Car 2: Used car Model: Toyota Corolla Year Made: 1999

Selling Price: 15000
Car 4: New car Model: BMW 320i Year Made: 2004
Price: 35000 Color: Black
Selling Price: 35000
Car 5: Used car Model: Toyota Sienna Year Made: 2000
Price: 11000
Body Condition: good Selling Price: 11000
Car 2: Used car
Model: Toyota Corolla Year Made: 1999
