Define the terms class, object and message. How does the concept of message passing help to encapsulate the implementation of an object, including its data? List all of FoodCo’s products that are described in the case study material in chapter B1. Arrange these into a hierarchy. Imagine some other products that make your hierarchy more interesting and add them to your description. If these were classes in an object model and were part of an inheritance hierarchy, would your resulting hierarchy comply with the Liskov Substitution Principle? If the resulting hierarchy would comply, explain some potential benefits of structuring classes into an inheritance hierarchy in this way. If the resulting hierarchy does not comply, explain some potential problems that may arise in future development of the model.
