Question
IN JAVA
I need help with the extPerson class within the problem. I've already defined the classes that this class will extend, however I have no idea how to start this problem. The problem is located below:
Using classes, design an online 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 (as defined in Example 8-8, Chapter 8), theclassDate (as designed in this chapter's Programming Exercise 2), 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 AddressBookshould 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 disk, or 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.

Any help is appreciated!!
Explanation / Answer
Below is your code. It was a big project, So I tried putting up everything I could. If something is left please comment, If I am able to solve, I'll do for sure.
Person.java
public class Person {
private String firstName; // store the first name
private String lastName; // store the last name
// Default constructor
// Initialize firstName and lastName to an empty string.
// Postcondition: firstName = ""; lastName = "";
public Person() {
firstName = "";
lastName = "";
}
// Constructor with parameters
// Set firstName and lastName according to the parameters.
// Postcondition: firstName = first; lastName = last;
public Person(String first, String last) {
setName(first, last);
}
// Method to output the first name and last name
// in the form firstName lastName.
public String toString() {
return (firstName + " " + lastName);
}
// Method to set firstName and lastName according to
// the parameters.
// Postcondition: firstName = first; lastName = last;
public void setName(String first, String last) {
firstName = first;
lastName = last;
}
// Method to return firstName.
// Postcondition: The value of firstName is returned.
public String getFirstName() {
return firstName;
}
// Method to return lastName.
// Postcondition: The value of lastName is returned.
public String getLastName() {
return lastName;
}
}
Date.java
public class Date {
private int dMonth; // variable to store the month
private int dDay; // variable to store the day
private int dYear; // variable to store the year
// Default constructor
// The instance variables dMonth, dDay, and dYear are set to
// the default values.
// Postcondition: dMonth = 1; dDay = 1; dYear = 1900;
public Date() {
dMonth = 1;
dDay = 1;
dYear = 1900;
}
// Constructor to set the date
// The instance variables dMonth, dDay, and dYear are set
// according to the parameters.
// Postcondition: dMonth = month; dDay = day;
// dYear = year;
public Date(int month, int day, int year) {
dMonth = month;
dDay = day;
dYear = year;
}
// Method to set the date
// The instance variables dMonth, dDay, and dYear are set
// according to the parameters.
// Postcondition: dMonth = month; dDay = day;
// dYear = year;
public void setDate(int month, int day, int year) {
dMonth = month;
dDay = day;
dYear = year;
}
// Method to return the month
// Postcondition: The value of dMonth is returned.
public int getMonth() {
return dMonth;
}
// Method to return the day
// Postcondition: The value of dDay is returned.
public int getDay() {
return dDay;
}
// Method to return the year
// Postcondition: The value of dYear is returned.
