Hello! I am asking for help with a class assignment.
In the zip file below, I have attached all the files. The UML diagram and initial Design proposal were just required for class, if you have a better way to do it, I encourage you to do so.
I would like the state persistence to be coded in a way such that I can take it out for the first version. The current version will be submitted now, and when the final is due, I will submit the version with state persistence implemented.
You are looking mainly at the Project Description PDF to see what the project needs to do.
Do not worry about the evidence of testing or discussion. I just need working code and I will figure the rest out.
Thank you so much for the help. Don't hesitate to text me if you have any questions.
