Question

Consider the following scenario: A chicken, eagle and duck are birds. A dog, cat, cow, and lion are animals. Human and Birds are also animals. Peas, carrots, and grass are plants. Chicken, duck, cow, and plants are edible. Draw a class diagram for the above scenario. You can use classes, inheritance, interfaces, and associations (including composition or aggregation) when needed. You shouldn’t use operations. (4 points)

Answer 1

To create a class diagram for the given scenario, one would define a base class 'Animal' with subclasses 'Birds' and main categories such as 'Dog', 'Cat', 'Cow', 'Lion', and 'Human'. Another class would be 'Plant'. The 'Edible' interface would be implemented by Chicken, Duck, Cow, and Plant to represent their edibility.

Step-by-step explanation:

Class Diagram for the Given Scenario

In this scenario, we can identify several classes and their relationships, which can be represented in a class diagram. First, we will define the classes and then show the inheritance and associations between them.

Birds and Animals are connected through inheritance since Birds are a type of Animal. Similarly, Chicken, Duck, and Cow are marked as Edible, showing an association with the Edible interface. The Plant class is separate but is also associated with the Edible interface.

Here is a simplified version of the class diagram:

Additionally, Human can be associated with both the Animal base class and all instances of the Edible interface, since humans consume various animals and plants.
