Hi Chris, I can try. As Philip says in the documentation inheritance is used when you have objects that are similar and share common variables and methods. An interface is used when you have two different classes that are very different but need to share one or more functions or variables.
What this gains you is you don't have a lot of extra methods and variables hanging around that you don't need. Keep in mind every variable you create in a class gets loaded onto the heap in memory that could be used for something else. There is no sense inheriting a super class if all you need is one variable and related functions that interact with that variable. Instead you can move that variable and related functions to an interface that can be shared between the two classes without dumping a bunch of unnecessary variables onto the heap. Does that make sense?
