Identify void and non-void return types: https://padlet.com/ctabares1/7uso90oqkd9s/wish/144120078
Void is more of an interactive return type where it will be for commands for objects within the world while non-void is more informational, like how int can help you see stats on the scenario or be used to input numbers as parameters while something like boolean will answer true and false based on the conditions or question asked.

27.) What is the difference between sub and super classes?

A superclass holds the subclasses under one broad genre, for example the superclass in the piano scenario would be world while the class named piano in the world class is a subclass of the superclass world. Within the actor class, actor is a superclass of any object within the world. Any object would be a subclass of the actor class.


28.) What kind of return types are commands? Which return types are questions?

A void return type would be a command because it does not receive information back, for commanding within the scenario. Boolean and int are more informational as boolean returns true or false response and int is numbers, does not interact with the code directly.
