6.1 Zoo Lab: Overview

In this lab we will be creating more specific animals classes and refactor our code to make use of inheritance.

6.1 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. Open the main window (MainWindow.xaml) in designer mode (right-click and click "View Designer" or press Shift-F7 to go to designer mode).

6.1 Zoo Lab: Object Diagram

Instantiate the objects and set their field values as specified in the following UML object diagram.
