Create a JAVA program using classes, design an address book to keep track of the names,

addresses, phone numbers, and birthdays of family members, close friends,

and certain business associates. Your program should be able to handle a

maximum of 500 entries.

a. Define the class Address that can store a street address, city, state, and

zip code. Use the appropriate methods to print and store the address.

Also, use constructors to automatically initialize the data members.

b. Define the class ExtPerson using the class Person , the class Date, and the class Address. Add a data member

to this class to classify the person as a family member, friend, or business

associate. Also, add a data member to store the phone number. Add

(or override) methods to print and store the appropriate information.

Use constructors to automatically initialize the data members.

c. Define the class AddressBook using previously defined classes. An object

of type AddressBook should be able to process a maximum of 500 entries.

The program should perform the following operations:

i. Load the data into the address book from a .txt file.

ii. Sort the address book by last name.

iii. Search for a person by last name.

iv. Print the address, phone number, and date of birth (if available) of a

given person.

v. Print the names of the people whose birthdays are in a given month or

between two given dates.

vi. Print the names of all the people between two last names.
