Question
Picky Publishing House publishes stories in three categories and has strict require ments for page counts in each category. Create an abstract class named Story that includes a story title, an author name, a number of pages, and a String message. Include get and set methods for each field. The method that sets the number of pages is abstract. Also include constants for the page limits in each category. Create three Story subclasses named Novel, Novella, and ShortStory, each with a unique setPages() method. A Novel must have more than 100 pages, a Novella must have between 50 and 100 pages inclusive, and a ShortStory must have fewer than 50 pages. If the parameter passed to any of the set methods in the child class is out of range, set the page value but also create and store a message that indicates how many pages must be added or cut to satisfy the rules for the story type. Write an application named StoryDemo that creates an array of at least six objects to demonstrate how the methods work for objects created both with valid and invalid page counts for each story type. For each story, display the title, author, page count, and message if any was generated. Save the files as Story.java, Novel.java, Novella.java, ShortStory.java, and StoryDemo.java
Write an exception program to display the invalid page count message and save it as InvalidPageCountException. Java. Adapt the previous programs to use the Exception program
BELOW IS THE CODE I ALREADY HAVE.
public abstract class Story
{
private String title;
private String authorName;
protected int numberOfPages;
private String message;
protected final int MIN_PAGES_IN_NOVEL = 101;
protected final int MIN_PAGES_IN_NOVELLA = 50;
protected final int MAX_PAGES_IN_NOVELLA = 100;
protected final int MAX_PAGES_IN_SHORT_STORY = 49;
public Story(String title, String authorName)
{
this.title = title;
this.authorName = authorName;
}
public String getTitle()
{
return title;
}
public String getAuthorName()
{
return authorName;
}
public int getNumberOfPages()
{
return numberOfPages;
}
public String getMessage()
{
return message;
}
public void setTitle(String title)
{
this.title = title;
}
public void setAuthorName(String authorName)
{
this.authorName = authorName;
}
public abstract void setPages(int numberOfPages);
public void setMessage(String message)
{
this.message = message;
}
public String toString()
{
String retString = ">>>Title: " + this.getTitle() + ", Author: " +
this.getAuthorName() + ", Number of pages: " + this.getNumberOfPages();
if (!this.getMessage().isEmpty())
{
retString = retString + " Note: " + this.getMessage();
}
return retString;
}
}

OUTPUT:
>>>Title: Moby-Dick, Author: Herman Melville, Number of pages: 350
>>>Title: The Great Gatsby, Author: F. Scott Fitzgerald, Number of pages: 98
Note: You still need 3 pages.
>>>Title: Breakfast at Tiffany's, Author: Truman Capote, Number of pages: 83
>>>Title: The Time Machine, Author: H.G. Wells, Number of pages: 300
Note: You have 200 extra pages.
>>>Title: The Lottery, Author: Shirley Jackson, Number of pages: 70
Note: You have 21 extra pages.
