Assignment Description
This assignment will give you practice with interactive programs, if/else statements, arrays, loops and methods.
Problem Description
A small car yard dealing in second hand cars needs an application to keep records of cars in stock. Details of each car shall include id (unique for each car), model, year of manufacturing, price paid for the car (i.e. purchase price) and selling price.
Selling price is calculated as old price plus mark-up of 30%. For example, Ford Transit bought for $20,000 will have the selling price of 20000 * (1 + 0.3) = 26000.
The car yard does not buy cars manufactured before 2009.
Task Requirements
Imagine you have been invited to develop a menu driven java application to manage records of cars in stock.
Familiarise yourself with the problem description provided above and complete the following tasks.
1. Develop a UML class diagram based on the problem description. The name of the class must be Car
a. Identify all the required attributes (includes id and selling price) for the Car class.
b. Identify a constructor for the class. Attributes id and selling price are calculated fields and should not be included as constructor parameters.
c. Identify all the set and get methods for each of the attributes identified in 1.a
2. Write a Java implementation of the UML diagram defined in 1. In your class, include comments describing the function of the class, the name of the programmer and the date of implementation.
3. Write a Java program (driver class) named CarYardMITnnnnn (nnnnn is your MIT ID) with a main method. Within the main method, design and implement the menu driven program functions of buying, selling, displaying and terminating the program as described below. Include comments describing the function of the program, the name of the programmer and the date of implementation.
a. Declare all required variables including the list of cars (arrays/ArrayList) as static variables.
b. Include static methods to implement buy, sell, and display functions
c. Populate the list of cars (arrays) on start-up with three car objects of your choice which should be displayed when user selects option three (3) from program Menu.
d. Program displays a main menu on execution and allows user to interact with the program until the user selects menu option four (4) which terminates the program.
Description of Program functions
Program displays a menu on execution. Four menu options are available to allow the user to buy a car, sell a car, display all cars, and exit program respectively. Program functionality and screen output for each of the menu option when selected by the user follows:
Program menu on execution:
~~~ Main Menu ~~~
1. Buy Car
2. Sell Car
3. Display all cars
4. Exit
Enter menu choice (1-4):
Invalid menu choice: User enters 5
~~~ Main Menu ~~~
1. Buy Car
2. Sell Car
3. Display all cars
4. Exit
Enter menu choice(1-4): 5
