You'll change the public properties to private and then add "getter" and "setter" methods to the class to enable controlled access of the values of these private properties.
Note: the word "hooks" in this video does not refer to hooks in Drupal's API.
Note: PHP does provide magic methods for getting and setting which are explained in this tutorial: Magic Methods: __toString(), __get, __set.
