Java program.

Mike's Movie Theater is a local cinema showing the latest Hollywood hits. Create a class called Movie that stores basic information about a single movie: the title, the running time or length of the film (in minutes), the showtimes (as a single string, such as "11:00,3:15,7:30"), and the film's rating (R, PG-13, PG, or G). Include get and set methods for each; the setter for rating should check that the value is one of the four valid options and, if not, should set the rating to "Not Rated". Be sure to include a constructor that allows values to be set upon instantiation. Finally, a method called addPreviews should accept the number of previews to be shown prior to the movie, and then add 2 minutes for each to the movie's running time.

Demonstrate that your class works in a program called MovieDemo. It does not need to have user input, but make sure you demonstrate that all methods and fields work correctly.
