Question

Write a program that simulates an address book.

Driver main method should be as shown below. Add comments to explain functionality

import java.util.ArrayList;

public class LastFirstChapter10

//Replace LastFirst with your Last Name and First Name

{

public static void main(String [] args)

{

ArrayList aBook = new ArrayList();

//Replace LiFi with Last Initial First Initial (for all instances)

for (int count = 0; count < 1; count++)

{

//****************************

//add code here to add new entry to ArrayList

//call addEntry

//print blank line

//****************************

}

int foundIndex = LiFiAddressBook.search(aBook);

System.out.println();

if (foundIndex > -1)

aBook.get(foundIndex).display();

else

System.out.println("No Entry Found");

}

}

25%

Output should be as shown in example at bottom.

LiFiAddressBook.java class

Instance variables:

First Name (string)

Last Name (integer)

Street Address (string)

City State (string)

Zip Code (string)

addEntry method:

Get input for variables above. See sample in example at bottom.

search method:

Receive ArrayList as argument

Output Search Menu (see example at bottom)

Utilize a switch and search ArrayList for field specified.

Return index number if entry found or -1 if not found

display method:

Print results as shown in example at bottom.
