In this version, you will be adding some inheritance, as well as introducing some collection classes – ArrayList and Map. The basic operation output is similar to the previous versions, with the following changes • Multiple phone numbers are allowed for a phone book entry • Each phone numbers is accompanied by a description (e.g. 'mobile', 'home', etc.) • The phonebook array is replaced by a map (which supplies the lookup functionality directly). • Reverse lookup goes away • A command line argument is used to determine the phonebook file to be used Sample Test Run #1 For example if the file phonebook.text contains: 1 mobile (123) 456-7890 2 home (234)567-8901 work (243) 123-6574 3 cell (345) 678-9012 work (324) 564-0987 fax (987) 234- David Harrow Keith Jones Jackie 9823 here is a sample execution of the program: lookup, quit (1/g) ? 1 last name? Jones first name? Jackie Jackie Jones's phone numbers: [cell: (345) 678-9012, work: (324) 564-0987, fax: (987) 234-9823] lookup, quit (1/g) ? 1 last name ? Doe first name? John -- Name not found lookup, quit (1/g) ? q Sample Test Run #2 If the application is run without a command line argument, the output should be: Usage: RhonekaakARR 'phonebook-filename'

In PB3 your map will have (key, value) pairs as (Name, PhonebookEntry) Take note: Name has to be unique. I recommend using TreeMap and implementing for the Name class Comparable<Name> private Map<Name, PhonebookEntry> map = new TreeMap<Name, PhonebookEntry> (): 1. Change the PhoneNumber class to have 2 strings: number and description (you can write a class ExtendedPhoneNumber that inherits your old PhoneNumber class) 2. change the PhonebookEntry class to have an ArrayList of type ExtendedPhoneNumber 3. change the Phonebook class to have a Map with the new PhonebookEntry as the value type
