Question

1. Maryland Animal Sanctuary and Rescue is a small Pet adoption place right here in our area and has different animals up for adoption. Design an application for their pets, creating a class diagram and writing the pseudocode for both the class definition and the application. Be sure to follow the Style Criteria for naming conventions, class diagrams, pseudocode, keywords, and operators.
   1. Create the UML class diagram for the Pet class that contains the type of the pet, the breed of the pet, and the weight. Examples of valid values for the type of the pet are "dog" and "rabbit". Examples of valid values for the breed are "husky" and "checkered giant". Examples of valid values for the weight are 32 and 3 1/2. Be sure to choose the most appropriate data type for the attributes. Include the methods of the Pet class listed below as well as the application class. Add the correct relationship and multiplicity.
   2. Create a class definition
      • Create a Pet class that contains the attributes in the class diagram. Additionally, include the following:
        • A default constructor that initializes each attribute to some reasonable default value for the pets.
        • Another constructor method that has a parameter for each data member. This constructor initializes each attribute to the value provided when an object of this type is instantiated.
        • Accessor and mutator methods for each attribute.
        • A method that displays all the data about the pets.
   3. Create the main application
      • Write the pseudocode for the application program for the pet sanctuary with a main() module that instantiates two objects of the Pet class.
        • The first object should be named dog and use the default constructor.
        • The second object should be named cat and use the second constructor to initialize the type to "cat", the breed to "Siamese", and the weight to 3.  
      • Include the following instructions in the main() method, in the order specified below
        • A call to set the type of the dog to "Large Dog".
        • A call to set the breed of the dog to “German Shephard”.
        • A call to set the weight of the dog to 50.
        • A Statement that displays the breed of the cat, using the appropriate method call.
        • A call to change the weight of the dog to 45.
        • A statement that displays the weight of the dog, using the appropriate method call.
        • A call for the cat object to the method that displays all the information about the cat.
        • A call for the dog object to the method that displays all of the information about the dog.
