Assessment regulations
Refer to section 4 of the“How you study”guide for undergraduate students for a clarification of how you are
assessed,penalties and late submissions,what constitutes plagiarism etc.
Penalty for Late Submission
If you submit your coursework late but within 24 hours or one working day of the specified deadline,10 marks
will be deducted from the final mark,as a penalty for late submission, except for work which obtains a mark in
the range 40 – 49%,in which case the mark will be capped at the pass mark (40%).If you submit your
coursework more than 24 hours or more than one working day after the specified deadline you will be given a
mark of zero for the work in question unless a claim of Mitigating Circumstances has been submitted and accepted as valid.
It is recognised that on occasion, illness or a personal crisis can mean that you fail to submit a piece of work on
time. In such cases you must inform the Campus Office in writing on a mitigating circumstances form, giving
the reason for your late or non-submission. You must provide relevant documentary evidence with the form.
This information will be reported to the relevant Assessment Board that will decide whether the mark of zero
shall stand. For more detailed information regarding University Assessment Regulations, please refer to the
following website:http://www.westminster.ac.uk/study/current-students/resources/academic-regulations
Coursework Description
Objectives:
The aim of this coursework is to assess the knowledge and skills that you have acquired about object-oriented
programming during the module. You are asked to implement a program in which objects interact in order to
fulfil with a set of functional requirements.
Analyse the problem statement:
An important skill that you will start to develop in this module is analysing a problem statement in order to
identify the details needed to develop a solution.
In this assignment, the first task you should perform is a careful analysis of the problem statement in order to
make sure you have all the information to elaborate a solution. If you have any questions please write your
queries on the Padlet on BB.
Design a solution
The design of your system should be consistent with the Object Oriented principles and easy to understand by
an independent programmer.
You are required to design your program using UML diagrams. In particular you have to draw:
• two use cases for the system (6 marks).
• a class diagram (6 marks)
Problem description and requirement statement
You are required to develop a program that implements a basic vehicle rental system.
You should implement a console system from where the manager can add new vehicles, delete if needed, edit
the vehicle information, etc. (as described in detailed below).
You should implement a Graphical User Interface (GUI) from where a customer can see the list of vehicles and
book available vehicles for specific dates.
In this assignment, you will be required to implement the following functionality:
1. According to the Inheritance principle you have to design and implement a super class Vehicle (6 marks)
and the subclasses Car and Motorbike.The classes should include appropriate methods in order to
comply with the encapsulation principle and hold information about the Plate number, and the Make
(You can add any other information that you consider appropriate for a rental vehicle system and you can
implement additional classes with justification to make the code more robust or user friendly).
In particular:
• The Car class should hold specific information and methods. You should add at least 2 instance
variables (attributes that you believe are important to be held in this class) and the relative get/set
methods (5 marks).
• The Motorbike class should hold specific information and methods.You should add at least 2
instance variables (attributes) and the relative get/set methods (5 marks).
• You should implement a class Schedule to represent the time slot when a vehicle has been booked.
The class should have a pick-up date and a drop-off date (to represent the date you can use either
the class provided during tutorials or you can use any java API). (5 marks).
2.Design and implement a class called WestminsterRentalVehicleManager,which implements the
interface RentalVehicleManager (2 marks). WestminsterRentalVehicleManager maintains the list of the
vehicle to rent and provides all the methods for the system manager.
The class should display in the console a menu containing the following management actions from which the
manager can select one.
• Add a new vehicle in the rental system. It should be possible to add a new vehicle, either a car or a
motorbike with all the relevant information. You should consider that in the rental car park there
are max 50 parking lots (5 marks).
• Delete a vehicle from the system,selecting the plate number.Display a message with the information of the vehicle that has been deleted (if it is a car or motorbike) and the number of
available parking lots in the garage (5 marks).
• Print the list of the vehicles in the system. For each vehicle, print the plate number, the type of
vehicle (if is a car, a van or a motorbike). The list should be ordered alphabetically according to the
vehicle make (5 marks).
• Write/Save the vehicle stock list in a file after any changes (5 marks).
Create a Graphical User Interface (GUI) that can be opened selecting an option from the menu
console (? marks).
You should implement the GUI according the following specification:
• The user can visualise the list of vehicles in WestminsterRentalVehicle system (8 marks).
• The user can filter the vehicles according at least one parameter (e.g. the type of the vehicle,
or the engine size, or the make, etc.) (4 marks).
• The user can check the availability of the vehicle in specific dates and can book make a
reservation if it is available (8 marks).
Note: You can choose how the GUI should look like and how to meet at the best these specifications.
3. Testing and system validation:
• Write a test plan designed to ensure that the coded solution works as expected. The test plan will
include specific instructions about the data and conditions the program will be tested with (5marks).
• Implement an automated testing (you can use JUnit or feel free to use any other tool or scripts for
unit testing) that runs scenarios of each of the use cases you implemented in the console menu (10 marks).
• The following will be evaluated:
o The robustness of the code through the use of error handling and input validation (5marks).
o The quality of the code and the adherence to coding standards and conventions (5 marks).
Demonstration
You will be expected to be familiar with your code and required to make any ad-hoc changes during
the demonstration
Please note that no marks will be given to a task if there is no understanding of the code.
Note that the maximum mark for work marked without a viva/demonstration shall range from 1-30% only.
Coursework Guidance
The implementation goals are split into 4 phases:
Phase I This involves an initial design of your system through UML diagrams and the implementation of the
classes Vehicle, Car, Motorbike and Schedule (plus any accessory class you might need), and the Interface
RentalVehicleManager. The marking scheme allows for students to score up to 35%. I would suggest
concluding this Phase 1 by Week 05.
Phase II This is for implementing the system functionalities through a console menu. You should provide the
implementation (in the class WestminsterRentalVehicleManager) of methods to add, delete, print, sort
vehicles and generate report. The marking scheme allows for students to score up to 55%. I would suggest
concluding this phase 2 by Week 07.
Phase III This phase involves the GUI implementation and the possibility for a user to visualise and book a
vehicle. The marking scheme allows for students to score up to 75%. I would suggest concluding this phase 3
by Week 09.
Phase IV This phase is dedicated to the testing and evaluation of your system and the marking scheme allows
for students to score up 100% for completing all the phases. This Phase 4 needs to be concluded by week 11
(week of final submission).
