Chapter 9 of the text
Moodle:  Class Coding Style
Java Classes

Java Application – Chapter and ChapterReader

Create a class to encapsulate the data and behavior of a chapter from Assignment 9.  The class should have something like the following fields:

Chapter Number – int
Chapter Title – String
Starting Page Number – int
Ending Page Number – int

Use appropriate access modifiers when defining the data

Code accessor and mutator (get and set) methods for all class instance variables. Be sure to follow the class style and use _<classInstanceVariable> as the name for the parameter corresponding to the class instance variable. (Note the “_” starting the parameter name.) You will need to make a method that returns the number of pages in the chapter.

If the chapter title is blank, or the values passed for the chapter number or page numbers are not valid, leave the associated instance variable unchanged.

The main method in this class should read the table of contents from a text file named toc.txt and use the class mutators to put the information into the Chapter object. The Chapter object should then be passed to a method to display chapter information using the class accessors and member method.

The toc.txt file contains semi-colon delimited fields for the chapter number, title, starting page, and the ending page for each book chapter. Download this file from Moodle and use it in your application.

The program output should appear as shown here:
