Summary
A car hire company is an organisation that generally rents vehicles to clients over a time frame of a
couple of days to a couple of weeks.

Hiring a car is a common practice for those who have taken a plane to a destination and wish to be
able to manage their own transport needs on the ground. It is also becoming increasingly common
for residents of a town to avoid the ongoing expenses of owning their own car, and to simply hire a
car locally whenever they need one.


In this assessment task you will create your own Java based (command line) program that will allow
a customer to make a partial booking of a vehicle through a car hire company.

It is strongly recommended that you read through the entire assessment before commencing any of
the tasks.
Scenario
Carrington Cars has been a player in the car rental market for many years. The organisation prides
itself on customer service and has numerous rental centres in convenient locations around the city
of Melbart. The organisation has recently seen a significant increase in the number of customers
arriving at their centres without securing a booking online. In many cases the staff at centres are
overwhelmed, leading to delays in customer support. In an effort to streamline the customer service
experience Carrington wish for customers to be able to make a partial booking onsite
using an in-store console-based system. This partial booking is then finalised by Carrington staff in
person with the customer when they become available.


Implementation in Java
Your Java based implementation will be console based. As such the Car Booking system will be
implemented with text prompts, standard output, and an ASCII-art drawing where required. You will
also need to read data from a file in CSV format.

Initially when the program starts, the following should be in place:
• a welcome message
• A prompt to the customer to retrieve the file, as shown in the figure 1.
• Figure 2 shows the session trace for booking operation

Figure 1: The user enters the file name (carlist.csv).
Cars available and the totals displayed.
The user gets two option to proceed ahead.

Figure 2: Make a booking option selected.
Allows the user to select the car from the car list.
Enters the start, end dates and the customer details.
Generates the summary based on the details entered.
Menu option displayed for another booking or exit the program.

Solution design
The solution will comprise of eight classes as outlined below
It is expected that your solution will have the following functionality:
• The user should be presented with an initial welcome message
• The program should ask the user for the file name to retrieve the records and display in a
tabular format. An appropriate error message should be displayed if the file is unable to be
retrieved.
• Details on the cars to be hired (including daily rates) are to be retrieved the ‘CarList.csv’
file.
• The program should allow the user to enter a selection to proceed or exit from the program
o Make a booking
o Exit
• The program should allow a user to select a car that they would from the list
• The program should prompt the user for the start and end dates of a hire.
• The program should capture the following details from a user
o Name
o Email
o Address
• There are two types of Cars:
o Standard Cars (as represented in the Car class). Standard cars have a base daily
rate of hire.
o Premium Cars (as represented in the PremiumCar class, an extension of the Car
class). On top of the daily rate, premium cars have extra costs as outlined below
The program should be able to manage the fact that there are extra costs associated with
the hire of Premium cars, those being:
o The need to pay insurance on the hire of a premium car. Insurance is calculated as
being 5% of the value of the daily rate.
• The program should calculate the cost of the hire dependent upon
o Daily rate of hire
o Number of days of hire
o Extra costs for Premium cars (as outlined above)
© Didasko 2019. All rights reserved. 7
• The following information should be displayed to the user as a summary
o Customer details
o Booking confirmation
o Car Hired
o Start and End dates of hire
o Number of days of hire
o Rate per day
o Total Cost of Hire


The following sections describe the classes that make up the program

Assessment Tasks
Task overview
The assessment is sub divided into UML and Java tasks. Out of these the first tasks are UML while
the rest are of Java. Ensure that you complete the tasks in sequential order i.e. you do not start a
task until the preceding tasks are finished.
Tasks 1-2: UML
Create a complete UML class diagram in Visio 2016 for the Car Rental program. Marks will be
awarded for classes (Task 1) and relationships (Task 2). Details of the classes and relationships are
given in the solution design section. The marking rubric below gives more details about the
components we are expecting.

Task 3: Test scenario 1
Download and fill in the Test_Case_Template.docx from the learning portal. The document can be
found in Week 8 for the subject. The template will be used for testing the inputs for the
CarAndBookingDates.validateDayString() method.
The test scenario should cover the following tests that generate valid outcomes
1. The day for hire is greater than zero
2. The day for hire is 30 or less for the month of November
…and the following test cases that generate invalid outcomes
3. The day for hire is less than zero
4. The day for hire is 32 or more for the month of January
5. The day for hire is 31 or more for the month of November.

a) Error handling for user input.
b) Consistent code indentation with one level of indentation per block.
c) Code commenting for each class, all methods, and some inline comments.
d) Good naming conventions.
e) Reasonable code line lengths.

Marks of allocated for following these best practices. Refer the rubric for further details.


Testing the code
After you have finished writing the code, test it by performing the following tasks. Your response
must include a screenshot of the output for each of the following tasks.

Task 4:

Run the code with the inputs to test for exception handling:
File name: car.csv

Task 5:

Run the code with the following inputs to validate the car number selection:
Car number: 6

Implementation tips for Tasks 4-9
Try to break down the logic in the assessment into small sections. In general, you should focus on
implementing, testing and running small sections of the assessment at a time. This ensures that
building blocks for your assessment are sound. Also, if you make any errors in your code, they will
be more easily identified and rectified.
If you find that any of the methods are particularly long, you are welcome to introduce additional
‘helper’ methods to break up your work.
Make sure that you lodge a support request if you would like any guidance.


Submitting your assignment
When you have completed your answers, submit the assessment on the Learning Portal. You should
submit the following:
