Suppose that you want to define for the Movie class a constructor that
takes four arguments: the familiar script, acting, and direction values,
plus the length of the movie in minutes. You want to use the
constructor to create new Movie instances as follows:
*-- Ratings for script, acting, and direction
|
| *-- Length
v |
------- v
new Movie(4, 7, 3, 88)
The fourth argument establishes the value of the minutes instance
variable inherited from the Attraction class.
