During the Exam

If you have a question or need a clarification during the exam, you can make a PRIVATE post on the Ed forum. Do not send a message to the lecturer (or tutors), you may not get a response.

When posting a message to the forum, it's important that you provide all the required details. Failure to do this may result in delays in responding to your queries.

To ensure that you are as prepared for your online exam as you can be, make sure you check each point listed in the "Online Exam Preparation Checklist". In particular, read the following sections:

• 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.
