or this assignment, you will select either the Cat or the Dog Java class from the UML diagram. Open the Virtual Lab (Apporto) by clicking on the link in the Virtual Lab Access module. Then open your Eclipse IDE and create a new class. Use the Eclipse IDE Tutorial if you need help with creating a class in Eclipse. Before you begin, review the following UML Class Diagram, paying special attention to the attributes and behaviors of each class. As a note, though the diagram illustrates an inheritance relationship between the classes, the class you choose to implement does not have to inherit from the Pet class for the purposes of this assignment. You will learn more about implementing inheritance in later modules. Next, you will implement either the Cat or Dog Java class. Your class must meet all of the specifications from the UML Class diagram. Be sure to include the following in your Cat or Dog class: All attributes (variables) with appropriate data types. Note that the types are…
