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.

Simple code example for polymorphism:

//This pseudocode indicates that when the driver object issues a call to moveCar, whichever object has been instantiated (FourWheel or FamilyCar) will move.

Class Driver:

     Car myCar;

     myCar := new FourWheel;

     myCar.moveCar(); 

     myCar := new FamilyCar;

     myCar.moveCar();
