Exercise

Writing a non-public method

In the lesson, we covered how to add functionality to classes using non-public methods. By defining methods as non-public you're signifying to the user that the method is only to be used inside the package.

In this exercise, you will define a non-public method that will be leveraged by your class to count words.
