Create a class named Movie that can be used with your video rental business. The Movie class should have ID Number, and movie title with appropriate getter and setter methods.

Next, create three additional classes named Action, Comedy, and Drama that are derived from Movie. Finally, create an overridden method named calcLateFees that takes as input the number of days a movie is late and returns the late fee for that movie. The default late fee is $2/day. Action movies have a late fee of $3/day, comedies are $2.50/day, and dramas are $2/day. Test your classes from a main method.

Q   Imagine a publishing company that markets both book and audio-cassette versions of its works. Create a class publication that stores the title and price of a publication. From this class derive two classes:  a. Book, which adds a page count  b. Tape, which adds a playing time in minutes. Each of these three classes should have set() and get() functions and a display() function to display its data. Write a main() program to test the book and tape class by creating instances of them, asking the user to fill in their data and then displaying the data with display(). Solution code class Publication{ int price ; String title ; public Publication ( int price , String title) { this . price = price ; this . title = title ; } public int getPrice () { return price ; } public void setPrice ( int price) { this . price = price ; } public String getTitle () { return title ; } p...
