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

All coursework code on this module is submitted via Blackboard. It may be automatically scanned through a text matching system

(designed to check for possible plagiarism).

You DO NOT need to attach a copy of the CA1 form;

To submit your assignment:

? Log on to Blackboard at http://learning.westminster.ac.uk; and follow the instructions below.

If you are unable to submit your work on Blackboard due to a finance hold you must email your work to ecs-registry@westminster.ac.uk

by the same deadline, putting on the subject line the module code, assessment number, and your name. This shows that you have

completed your work by the deadline. After the finance hold is lifted you must then submit the same work as normal on Blackboard,

otherwise it will not be marked and you will get a fail for that part of the assessment.

Airplane seat booking - Coursework and In-Class Test

You are to be assessed on how well you know methods, arrays, and array manipulation code. Most

of the marks will come from your in-class test result. Please refrain from copying other student’s

code. It is OK to discuss how to implement the solution, but the code you write must be your own. A

good way to test your understanding of the code is to make sure that you can write the code

yourself without needing to look at your friend’s code, or follow a Youtube video. Concentrate on

developing the code step by step and make sure you always have a running version of your program.

That way, if you add code and it causes problems you will know that the problem was caused by

your new code. Write your test cases as you are developing each method and thoroughly test your

code before implementing additional methods.

Airplane seat booking program.

Task 1. Design and implement a program for booking seats on an Airplane with 12 seats. You will

need to adhere to good programming style and conventions, for example, avoid magic numbers in

your code by declaring a global constant (final) to represent the number of seats for your airplane.

static final int SEATING_CAPACITY = 12;

All other variables must be local. Pass variables as parameters if they are needed in other methods.

The Airplane’s seating will be represented by an array of strings.

String [] airplane = new String[SEATING_CAPACITY];

In this representation, airplane[4] = “e”, means that seat 4 of the airplane is empty, airplane[0] =

“Pilot” means that seat 0 is occupied by the pilot of the airplane, and, airplane[1] = “Mary Drew”

means that Mary is occupying seat 1. You must not allow a passenger to book the pilot seat. (Hint.

You may start by using code which is similar to the hotel code given in your notes)

Once the basic code runs then add code to ‘Views All seats’ and ‘Add passenger to seat’ into

separate methods, and test it works. You can build up your test cases as you develop your program

(see 2 below).

Then add a menu system which will allow the user to choose what they want to select. Enter an ‘A’

to add a passenger to a seat, and a ‘V’ to view all seats. Ensure that all menu options call a separate

method to execute the option. When an ‘A’ is pressed it should call the Add method, a ‘V’ should call

the View method.

One by one, add extra methods to do each of the following. The user should be able to choose from

the menu what the program does, until they enter ‘Q’ which should quit the program.

E: Display Empty seats

D: Delete passenger from seat

F: Find the seat for a given passengers name

S: Store program data in to file

L: Load program data from file

O: View seats Ordered alphabetically by name. (Using the bubble sort algorithm in the notes)

Task 2. Create a table of test cases showing how you tested your program (see below). Write a

brief (no more than one page) discussion of how and why you chose your test cases and comment

on your test coverage. Also discuss whether you would “sign off” to having your program used

commercially, and if not, what still needs to be done so that you can confidently “sign off”.

Test Case Expected Result Actual Result Pass/Fail

(Seats Initialised correctly)

After program starts, Press ‘E’

Displays ‘e’ for all seats Displays ‘e’ for all seats Pass

(Add passenger “Bob” to seat 5)

Press ‘A’, enter “Bob”

Press ‘V’ Displays “Bob” for

seat 5

Displays “Bob” for seat 4 Fail

….etc…. ….. ….. …..

Submission Instructions:

1. Java Program code to be submitted as a single text file by the date shown above on Blackboard

4COSC005 ‘Submit Coursework’ link. For this submission you should copy and paste your program

into a text file, type the filename at the top of each piece of pasted code, and at the very top of the

text file type your name and ID number. Call this saved file by your ID number (e.g. . w123456.txt )

and ensure it is saved as plain text (not .doc or .zip). Do not change your code after it has been

submitted.

2. Submit your test table and report separately as a pdf or word document.

3. Submit your self assessment form as a separate word document.

Tutorial in-class test.

There will be a short in-class test in the Workshop tutorial session following the submission of the

coursework. We need to know that you fully understand the code you use, and have not just

stumbled on a solution, or copied it from elsewhere. For the test you will be assessed on how well

you know arrays, array manipulation code, and methods, so look at the examples in the notes as

well as understanding your Airplane program.

Do not attempt to go to the wrong tutorial group without the tutor’s permission. If you miss the test

there will be no other opportunity to redo the work in a later week unless you have approved

mitigating circumstances. Sign-in on the class list during the test.

Marking Criteria

80% of the marks will come from the in-class test result. If you score 30% or less in the in-class test

then your code solution mark will be limited to a maximum of 50% as the test will have proved you

did not really understand the code.

20% of the marks will come from your ‘Airplane’ code solution.

Code marking (see self assessment form):

20% - A basic menu loop which prompts for input until 'Q' is pressed.

+25% A reasonable attempt at (A V E D F) options (5% each).

+20% For options (S L) Save and Load of the Airplane seating configuration (10% each)

+20% For option ‘O’ – bubble sort implementation and not library sorting routines.

+10% Test cases and test coverage report.

+5% Self assessment and demonstration.

Warning: All code must be done by yourself to ensure you can answer questions during the test and

demonstration. You will be capped at 50% if you cannot explain the code or received less than 30%

in the in-class test.

Pass grade: A basic code solution and 40% in the in-class test.

Distinction grade (>=70%).
