Create object-oriented programs using a variety of objects you use in real-life
Create graphical user interfaces using MAUI that work with business logic objects
Using many objects will teach you to switch your hat when implementing your object-oriented programs
Draw your "thinking map" in UML to ensure you don't get lost
Implement something interesting with each object
Access the object's properties using accessor and mutation methods
Create object and set its properties
Interact with the user to ask for values of properties of the object
Extend in-class exercises with additional functionality
Add functionality to your objects (e.g. add perimeter calculation to an object that can calculate area)
Add information to your objects via field variables
Interactivity
Design/extend GUIs for the exercises we have done in class
Implement any TODOs left for practice in the in-class exercises
Re-create the same exercises from scratch. Just change the words (e.g. instead of Account use Employee)
Verify your understanding in the in-class exec ises
Use the Debugging functionality of the IDE for every program we have done in class
Incremental development
Do NOT write all the code before you compile and run the program for the first time
Run the program often.
If you think the code should have no runtime errors verify it by running the program
Debug the program often
Verify your assumptions
Compile very often. Know the keyboard shortcut.
If you think the code should have no syntax errors verify as often as you can
Take it step by step, one small step at a time
Must use your laptop
If your laptop is not working you will take the exam on paper
You will be evaluated as if you would have taken the exam using an IDE on your laptop
Make sure it works
Implement using the IDE used in class
DO NOT FORGET TO COMMIT YOUR FINAL CODE
There will be no time to study something for the first time during the exam. The open book is useful so you don't have to memorize things that are readily available like function names, predefined modules and classes etc.
NOT allowed access to AI assistants of any kind (e.g. ChatGPT, Perplexity, GitHub Copilot)
NOT allowed to post or send any information outside of the classroom on the Internet
NOT allowed any means of communicating with someone
NOT allowed to use someone else's work
Access to the professor's solutions for exercises and assignments
Access to YOUR OWN solutions for exercises and assignments
Access to the Internet for online documentation
Access to textbook(s)
Access to slides
Practice
Troubleshooting and fixing errors leads to very detailed and through understanding of what you are reading
Verify your solutions against solutions provided in SLATE
Practice using recommended execises
Complete all assignments using provided solutions
Finish all in-class exercises
