Question

Must be written in JAVA Code

Modify the program you created in previous project to accomplish the following:

Support the storing of additional user information: street address (string), city( string), state (string), and 10-digit phone number (long integer, contains area code and does not include special characters such as '(', ')', or '-'

Store the data in an ArrayList object

Program to Modify

import java.util.ArrayList;
import java.util.Scanner;

public class Address
{
String firstname;
String lastname;
int zipcode;
  
Address(String firstname,String lastname,int zipcode)
{
this.firstname = firstname;
this.lastname = lastname;
this.zipcode = zipcode;
}

public String toString()
{
return this.firstname + " " + this.lastname + " " + this.zipcode;
}

public static void main(String[] args)
{
Scanner aa = new Scanner(System.in);
int n;
System.out.print("Enter a number up to 25: ");
n = aa.nextInt();
String firstname,lastname;
int zipcode;
ArrayList<Address> addr = new ArrayList<Address>();
aa.nextLine();
for(int i=1;i<=n;i++)
{
System.out.print("Enter First Name:");
firstname = aa.nextLine();

System.out.print("Enter Last Name:");
lastname = aa.nextLine();

System.out.print("Enter Zip Code:");
zipcode = aa.nextInt();
aa.nextLine();

Address ad = new Address(firstname,lastname,zipcode);
addr.add(ad);
}

System.out.println("\nFirstName/LastName/Zipcode");
System.out.println();
for(Address a:addr)
{
System.out.println(a);
}
}

}

import java.util.ArrayList;
import java.util.Scanner;

public class Address {
   String firstname;
   String lastname;
   int zipcode;
   // added variables
   String address;
   String city;
   String state;
   long phone;

   // changed constructor according to new variables
   public Address(String aFirstname, String aLastname, int aZipcode, String aAddress, String aCity, String aState,
           long aPhone) {
       super();
       firstname = aFirstname;
       lastname = aLastname;
       zipcode = aZipcode;
       address = aAddress;
       city = aCity;
       state = aState;
       phone = aPhone;
   }

   // added toString to return new fields
   public String toString() {
       return this.firstname + " " + this.lastname + " " + this.zipcode + " " + this.address + " " + this.state + " "
               + this.city + " " + this.phone;
   }

   public static void main(String[] args) {
       Scanner aa = new Scanner(System.in);
       int n;
       System.out.print("Enter a number up to 25: ");
       n = aa.nextInt();
       String firstname, lastname, add, c, s;
       int zipcode;
       long ph;
       ArrayList<Address> addr = new ArrayList<Address>();
       aa.nextLine();
       for (int i = 1; i <= n; i++) {
           System.out.print("Enter First Name:");
           firstname = aa.nextLine();

           System.out.print("Enter Last Name:");
           lastname = aa.nextLine();

           System.out.print("Enter Zip Code:");
           zipcode = aa.nextInt();
           aa.nextLine();
           System.out.println("Enter address: ");
           add = aa.nextLine();
           System.out.println("Enter city: ");
           c = aa.nextLine();
           System.out.println("Enter state: ");
           s = aa.nextLine();
           System.out.println("Enter phone: ");
           ph = aa.nextLong();
           aa.nextLine();
           Address ad = new Address(firstname, lastname, zipcode, add, c, s, ph);
           addr.add(ad);
       }

       System.out.println("\nFirstName/LastName/Zipcode/Address/City/State/Phone");
       System.out.println();
       for (Address a : addr) {
           System.out.println(a);
       }
   }

}
