177: Mainline

In the following definition of the Demonstrate class, a Movie instance is created, values are assigned to the instance variables, and the Movie instance's rating is computed by a class method named movieRating. The field-selection operator appears frequently:

public class Demonstrate { 
 public static void main (String argv[]) { 
  Movie m = new Movie(); 
  m.script = 8; m.acting = 9; m.direction = 6; 
  System.out.print("The rating of the movie is "); 
  System.out.println( 
   Movie.movieRating(m.script, m.acting, m.direction) 
  ); 
 } 
}
