Contact Lists

Create a menu-driven program to emulate a Contact Lists Application. You might see such apps in smartphones, you are free to go ahead and take ideas from your own contact applications.

Your menu-driven program must look like:

Welcome to DBC's Contact List App
Press 1 to add a new contact
Press 2 to view all contacts
Press 3 to search for a contact
Press 4 to delete a contact
Press 5 to exit program 

The 'Add a new contact menu'

You have chosen to add a new contact: 
Please enter the name of the Person
First Name: Divyansh
Last Name: Bhardwaj
Contact Number: 1234567891
Would you like to add another contact number? (y/n): y

Would you like to add another contact number? (y/n): n
Would you like to add email address? (y/n): y
Email Address: divyansh.bhardwaj@gla.ac.in

Information about the 'add a contact menu'

1. This program will store this Person as a type (you have to create a Person class). That means this program uses a list of Persons.

public class Person {
    // a field to store the first name
    // a field to store the last name
    // a list to store multiple contact numbers (i.e a list of numbers)
    // a field to store the email address of the person 
}
