2.1 Zoo Lab: Overview

Como Zoo has a vending machine and a birthing room.

This week you will be defining classes to represent these new ideas, and will be creating instances of these objects and setting their field values.

2.1 Zoo Lab: Class Diagram

Implement the changes specified in the following UML 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).
