Submission of incorrect file

If you have submitted the incorrect file, you should email the correct file

to the instructors prior to the deadline. Submitting the incorrect file can

result in failure.

Special consideration Requests for an extension due to illness, misadventure, or other

extenuating circumstances beyond your control will only be considered

via a formal application for special consideration through e-Bridge.

Report format ALL answers must be written in English.

The report must:

• be submitted as a .doc, .docx (do not submit PDF or Apple Pages)

• contain headings and subheadings

• have 3 cm margins

• use a legible font (e.g., Calibri, Arial or Times New Roman)

• be presented in 11 point font size with 1.5 line spacing

• be paginated

Plagiarism and

academic misconduct

It is assumed that you are thoroughly familiar with the policies of XJTLU

regarding academic misconduct and plagiarism. Ignorance of the rules is

not an acceptable defence against an allegation of academic misconduct.

There are no excuses for engaging in plagiarism. Assignment answers

will be checked for plagiarism. Impermissible similarities between student

answers (current and former) can be detected by academic integrity

software and by instructor, and will be referred to the School’s Examination

Officer for investigation. Penalties will follow those of the University’s

Academic Integrity Policy on e-Bridge and can ranged from capped marks

to expulsions from the university.

For use of Generative Artificial Intelligence (AI), see below.

Use of Generative

Artificial Intelligence

(AI)

Simple Editing Assistance

For this assessment task, you may use standard editing software but

not generative AI. You are permitted to use the full capabilities of the

standard editing software, such as Microsoft Office suite, Grammarly, and

Integrated Development Environments (IDEs) for coding. If the use of

generative AI such as ChatGPT is detected, it will be regarded as serious

academic misconduct and subject to the penalties mentioned above.

Tips • Read the questions carefully.

• Write succinctly, and avoid repetition.

• Avoid being overly descriptive.

• Remember to save/back up your work regularly. XJTLU provides all

students free access to XJTLU Box. It may be prudent to save your

work to your XJTLU account so that you can access it from multiple

devices in case you encounter hardware issues.

• You are encouraged to post administrative/procedural questions

about the assignment on the LM Q&A Forum. The instructors will

answer for the benefit of all students.

CPT111: Java Programming Semester 1, 2024-25

Coursework 3: Programming Project – A Simple Quiz System

The purpose of this assignment is to design and develop an application that can be used to facilitate

educational quizzes, allowing users to select topics of interests, take quizzes related to those topics,

and view their quiz scores on a personal dashboard. The primary aim is to create a user-friendly

and interactive platform that enhances the learning experience through topic selection and question

assignment.

1 Functional requirements

As this is a programming assignment, not a software design one, here is a skeleton to guide you in

the creative part.

1.1 At startup

• The program should load data, such as user information, questions, etc., from selected files,

and store it in memory (using relevant variables and data structure).

– You may assume that all user information are stored in a comma-separated values (CSV)

file1

, as illustrated in resources user.csv, where the 1st, 2nd, and 3rd columns of the

file represent the user id, user name, and password of the user, respectively.

– You can assume that all questions are stored in some XML files, as illustrated in folder:

resources questionsBank. A Java class ReadQuestions has been provided to

you in the src folder demonstrating how the questions can be read from the XML files

into the memory, and the Javadoc of the classes used can be found under the folder

repositories javadoc xjtlu.cpt111.assignment.quiz.

Note: You need to add the library:

repositories xjtlu cpt111 xjtlu.cpt111.assignment.quiz

0.0.1 xjtlu.cpt111.assignment.quiz-0.0.1.jar

to the class path (of your IDE) first before running the ReadQuestion class.

• The program should:

– show information about data loaded.

– validate the questions read. That is, in our case, a question is valid if it

(i) falls into a topic (either new or an existing one)

(ii) has a question statement,

(iii) has more than one answer available for selection, and

(iv) has one-and-only-one answer.

– show a menu that present a list of interactions possible.

• Besides, you may need to add more questions (under different topics) to the question bank

yourself.

1CSV file: a text file format that uses commas to separate values, and newlines to separate records.

1.2 Menu — General behaviour

The application should support, at least, the following functions.

• User registration and authentication

• Topic selection

– The topics available should be based on the input from the questions.

• Quiz taking

– You can decide the number of questions in a quiz. However, each quiz should contains

questions at different level of difficulties.

– The questions should be shown to the user one-by-one!

– The order of answers available for selection should be shuffled every time before a

question is shown to the user.

• The score of the quiz should show to the user immediately after the quiz has been finished

and the results should be saved into a score file

– You should design the structure (and format) of the score file on your own, and make

sure that you can read its content back when the program start!

• User dashboard for viewing quiz results of each topic and history of the previous 3 tests

attempted.

• Leaderboard for showing the names of the users with the highest score in each topic.

1.3 Technical requirements

The objective of this assignment is for you to program a simple quiz system so it should be interactive

in the form of showing text to the user and requesting their answer and data update through user

input as well as reading data from different file types. If you fail to do so, your submission will

automatically attract a penalty of 50%.

1.4 Concept requirements

Your code must feature and make use of the following elements.

• All your code must be divided in relevant/meaningful functions and classes.

• Declare/define and use variables with the appropriate data types and meaningful names.

• Input will always be converted into proper data type.

• The program should prevent crash in any situation, thus make sure you test your program

properly.

1.5 Constraints

Dependencies Using libraries or modules that are NOT covered in this course is strictly prohibited

and will result in zero (0) marks automatically in this assignment.

Internet connectivity The application is assumed to be run locally on a computer; hence no internet

connection is required.

2 Important reminder

Documentation is also a critically important part of your software engineering. Your use of comment

(in Java source file) will be graded.

You must write the final version of the program totally on your own. Sophisticated plagiarism

detection system are in operation, and they are pretty good at catching copying! Re-read the policy

on the university home page, and note the University’s tougher policy this year regarding cheating.

Using libraries or modules that are NOT covered in this course is strictly prohibited and will

result in zero (0) marks automatically in this assignment.

Your programming style (how clearly and how well you speak a programming language, i.e.,

Java in this course) is what will be graded. Correct functioning of your program is necessary but

not sufficient; you must use the concepts covered in class and meet all requirements stated in this

assignment and as detailed in the marking rubrics (Section 4).

3 Submission requirements

Your assignment has to submit to Learning Mall (LM). You should submit the following:

A. A report (written using Microsoft Word) that includes the following items:

1. A cover sheet stating the student number of your team members.

2. A description of your project

3. Information and explanation of how you add, store and handle users’ data (including the

data structure that you used to store users’ data in memory), the algorithm that you used

to identify the user names in the leaderboard, how to handle problems that appear in the

questions (e.g., questions with more than one correct answers) and other parts of the program,

etc.

4. Tests performed to verify the correctness of the program.

5. Printouts/screen capture of your program’s execution and tests. (This can be incorporated

into Items 3 and 4 above)

6. Peer evaluation form (Section A). (This will be used to adjust the final mark of individual

students according to his/her contributions to the project.)

B. ALL Java source codes and resource files (e.g., images, questions and users files, etc.) that are

required to run the application.

You should compresses all files into a single “.zip” file before submission. You should NOT include

any files from the repositories folder or any files that are NOT relevant to the application into

the submission file. Failure to follow this requirement will result in mark deduction.
