4.1 Zoo Lab: Overview

In this assignment, create methods and call them from button-click event handlers, passing parameters to them and accepting return values from them, as specified.

This week's object diagram is relatively simple. A couple fields are being deleted, and the two animals that used to be in the birthing room are instead only being added to the zoo's Animals list.

4.1 Zoo Lab: 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).
