will be provided with a Revision Package containing sample and a few past Exam
Questions in Week 10.
There are three parts,
Part 1: Multiple Choice (20 marks).
Part 2: Short Answer (25 marks).
Part 3: Programming Questions (55 marks).
The Final Exam will be available on the class webpage at 9am
AEST Tuesday 17 August 2021.
You must submit your answers by 12pm AEST Tuesday 17 August
2021 (after 3 hours). If you don't submit your answers for your
Final Exam, it will be considered as absent fail for the Final Exam.
During the exam, you can access the course material available on
the class webpage and your course work (your tut/lab solutions,
assignment and project work). You can also access Java API
available online. Please note that you must not access any other
pages on the internet. We will use sophisticated plagiarism
software/techniques to detect any possible breaches, so
importantly, please make sure that you submit your original
work and don't copy!
During your exam, you must not seek/get help from other
students, any other person or internet resources. Any
communications (physical, digital) after you or another person
has started the exam time will result in disciplinary actions as per
the UNSW guidelines. The use of code-synthesis tools, such as
GitHub Copilot, is not permitted in this exam. Sharing,
publishing, or distributing your assignment work after the
completion of the exam is not permitted.
We will award you marks for your final exam based on your
submissions for all three parts. All work submitted must be your
own.
You are warned: please do not plagiarise, it's not worth it!
Notes:
Answer all questions. Questions may not be worth equal marks. Questions
may be answered in any order.
All answers must be submitted online using the provided instructions in the

Fit to Sit
Technical Issues
Communication during the exam
Sharing answers with others or posting them online
Part 1: Multiple Choice (20 marks)
There will be approximately 10 to 15 multiple choice questions. The marks for each
question may vary. Part 1 uses Moodle Quiz module. You can attempt multiple times.
Your final selections will be marked. Make sure to "Finish attempt" and also
"Submit all and Finish".
Part 2: Short Answer (25 marks)
Part 2 uses Moodle Short Answer module. You need to submit your answers following
the required instructions on Moodle.
Please carefully read the instructions provided in the questions. For example, you
may be required to briefly explain/justify one or two or three most important points
in your answer. You do not need to write a long description in your answer.
Part 3 (of 3): Programming Questions (55 marks)
There will be 4 to 5 questions in this part.
You can use VLab or your own machine. You need to submit your answer files using
the provided instructions in the respective questions (using the provided give
command or via WebCMS). All answers must be submitted online.
Question One (16 marks)
Given a problem specification, model an Object-Oriented Design for a possible
solution. If suitable, you must use a Design Pattern(s) taught in the course in your
solution.
You will need to provide the following:
Interfaces (with brief Javadoc comments)
Classes (with brief Javadoc comments) and
Method signatures (with brief Javadoc comments)
In a file Q1.txt, write a brief rationale explaining your design choices,
examples of adhering to design principles taught in the course, and a
justification for any Design Patterns you may use in your solution.
For this question:
You do NOT need to implement methods; you are simply writing class and
method declarations as stubs.
You do NOT need to draw a UML diagram.
You need to submit the required files using the provided give command or via
WebCMS.
Question Two (12 marks)
Given a problem specification, implement a solution in Java. The problem will involve
Generic Programming and implementing a Class given a contract.
You will need to implement methods such that they properly use Generics and
follow the contract specified by the starter code;
If suitable, you may need to use a Design Pattern(s) discussed in the course.
We will provide a series of tests to help you in your implementation. Passing
the provided tests is NOT a guarantee of any marks.
We will run additional tests on your code. To ensure your solution passes our
additional tests, you will need to write your own tests that account for cases
which the given tests do not account for.
If you don't properly use generics, follow programming by contract and/or
implement a suitable design pattern as discussed in the lectures, you will not
be awarded marks, even if you pass the tests.
You need to submit the required files using the provided give command or via
WebCMS.
Question Three (15 marks)
Given a problem specification, implement your solution using a suitable design
pattern (one of the design patterns discussed in the course). You need to implement
the following and also provide a brief justification for your selected Design Pattern in
your solution:
In a file Q3.txt, provide a brief justification for your selected Design Pattern.
Interfaces
Classes
Methods
For this question:
We will provide a series of tests to help you in your implementation. Passing
the provided tests is NOT a guarantee of any marks.
We will run additional tests on your code. To ensure your solution passes our
additional tests, you will need to write your own tests that account for cases
which the given tests do not account for.
Importantly, if you don't use a suitable design pattern in your solution, as
discussed in the lectures, you will not be awarded marks, even if you pass the
tests.
You need to submit the required files using the provided give command or via
WebCMS.
Question Four (12 marks)
You will be provided with a problem, and an existing solution to that problem which
contains a series of Design Smells. Your task will be to refactor the code, both at
low-level (code level) and if required at high-level (use a design pattern(s) discussed
in the course).
You need to do the following:
In a file Q4.txt, briefly describe the Design Smells you identified, justify your
refactoring both at low-level (code level) and high level (use a suitable design
pattern, if required).
Refactor the code to remove the Design Smells, and if required, use a design
pattern(s) discussed in the course for refactoring.
For this question:
We will provide a complete suite of tests for you. After refactoring, the
behaviour of the system should remain unchanged (i.e. the tests should still
pass unchanged)
You need to submit the required files using the provided give command or via
WebCMS.
