Details

Forthisproject youaregoingtofurtherdevelop yourassignmenttwocode.

• identify three more functionalitiesthat may improve the grading system. For example, you may develop a unit/course/enrolment functionalitytolinkitwiththegrading system.Explain eachofthefunctionalitiesin details and what improvements would they bring to the system.
• Preparepseudocodefortheproposed threefunctionalities
• Basedonpseudocodebuiltjavacodetointegrate thesefunctionalitiesinyourassignmenttwo application. Forexample, anenrolment classcan be created that will allow studentsto record their enrolled units, status, and respective grade (if applicable). Please note, these new functionalities must be accessible by the users via themain menu of your application.

Thinkofnewfunctionalities

You willneed tothink ofagrademanagement systemofauniversity thatrequires furtherdetailslike enrolment, study progress, course information and payment status. These new functionalities ideally willrequire codeextensionlikeimplementingnewclass,methods, userinputandmewmenuoptions. Talk with your tutor if you are unsure of what scenario to use.
