Problem:

This assignment is intended as a means for you to practice file IO. You will be required to have an understanding of opening a file, closing a file, reading a file a line at a time and writing to a text file a line at a time. You will also be required to do some simple parsing of information read from a text file and formatting output to be written to a text file.

Create an AddressBookException class that you can use to throw exceptions in your address book. Your class should have a constructor that will allow you to set the particular message that corresponds to the error.

You should use your custom exception class to throw an error in the findPerson method if the person being searched for cannot be found, in the getPerson method if the AddressBook is empty. You should also throw an error any time that the addressbook file that you are attempting to read or write from cannot be opened.

In main test your AddressBook exception class by placing a try - catch around any code that could possibly throw an error. Supply a catch block to catch the AddressBook exception and provide a catch all block just in case an exception is thrown the you may have missed.
