Question
I am struggling to complete the computer programming assignment below. Any help would be extremely welcome.
Program Chapter 10
Comments are REQUIRED; flow charts and pseudocode are NOT REQUIRED.
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<LiFiAddressBook> aBook = new ArrayList<LiFiAddressBook>();
//Replace LiFi with Last Initial First Initial (for all instances)
for (int count = 0; count < 1; count++) //change 1 to add more than 1
{
//****************************
//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");
}
}

Output should be as shown in example at bottom.
LiFiAddressBook.java class
Instance variables:
First Name (string) Last Name (string) 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.
