4.2 Gradebook Assignment: Overview

Plato is the new instructor for the OOP2 class. This week we are finding students who are struggling with their homework, and helping them by offering tutoring sessions to get them off of probation.

In this assignment, you will create methods and call them by referring to the included UML sequence diagram(s).

4.2 Gradebook Assignment: Class Diagram

Implement the changes specified in the following UML class diagram.

Create any button(s) and button click event handler(s) in the WPF window designer (if specified in the class diagram).

  1. When creating classes be sure to:
    1. Ensure the class in the root namespace. This can be done in one of two ways. Either by adding the class in the project, i.e. scenario, or by adding the class to the business classes folder and removing the ".Business_Classes" designation from the namespace.
    2. insert the following line of code immediately above the class definition:
      [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.StyleCop.CSharp.MaintainabilityRules", "SA1401:FieldsMustBePrivate", Justification = "Encapsulation not yet taught.")]
  2. Open the main window (MainWindow.xaml) in designer mode (right-click and click "View Designer" or press Shift-F7 to go to designer mode).
