Polymorphic class diagram | Computer Science homework help

Polymorphism is one of the fundamentals of software engineering. Polymorphic behavior implies, at runtime, that the same message has different behavioral effects. For this week’s Critical Thinking Assignment, create a polymorphic class diagram of a design of your choosing. Add an aggregation relationship to this diagram. Write a sample pseudocode script to explain the polymorphic class diagram (see example below).

Additionally, in a one-page paper, explain why polymorphism is a runtime characteristic of object-oriented designs. Describe the structural design necessity to ensure polymorphism at runtime.
