AddressBook class lab assignment

AddressBook class

• The objective of this assignment will be to design and implement an address book
• Your address book will allow you to add, remove, and search for contacts
• The first version of our address book will use a Contact array, but future versions of AddressBook will not

Attributes

• a Contact array
• a size variable to keep track of the size
• a MAX_SIZE variable to set the maximum size

Constructors

• a default constructor
  • assign MAX_SIZE to 20
  • assign the Contact array to a new Contact array of MAX_SIZE elements
  • set the size variable to 0

Methods

• getter methods for the attributes
• setter methods for the attributes (do NOT make a setter for MAX_SIZE)
• boolean add(Contact newContact)
  • check if the current size of the AddressBook is still less than the maximum size
    • return false if the AddressBook is full
  • insert the new Contact in the next free element at the end of the contacts array
  • increment size
  • return true if the new Contact was successfully added
• void print()
  • traverse the Contact array and print out the entire AddressBook
• Contact find(String fn, String ln)
  • traverse the Contact array and find the Contact with the matching first name and last name
    • HINT: Use a loop and if statement
  • return the Contact with the matching first name and last name
  • return null if the Contact is not found

AddressBook Main

• Create a new file named AddressBookMain
• Create a new main method to test your AddressBook
• Your AddressBook demo should use a menu system (see AddressBook Menu System below)
  • When the user selects to ADD a Contact, you should prompt them for a first name, last name, phone, and address.
  • You should then create a new Contact
  • Add the Contact to your AddressBook using the AddressBook's add() method
  • The PRINT menu choice should print the entire AddressBook using the print() method
  • Make sure your menu runs again after the user makes a choice (HINT: use a loop somewhere)

AddressBook Menu System

• You will be creating a user interface menu for use with your AddressBook
• Open / create your AddressBook's main method
• Print out a message that explains the program (e.g. "Welcome to YOUR_NAME's address book!")
• Print out a menu with the following options:

(a)dd to address book
(p)rint address book
(q)uit

What would you like to do? 

• You should prompt for input after the menu is printed. Review Media:JavaIOExample.java for examples of input/output
• If the user inputs 'a', then print a message that says "USER SELECTED ADD"
• If the user inputs 'p', then print a message that says "USER SELECTED PRINT"
• If the user inputs 'q', then print a message that says "USER SELECTED QUIT"
