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
- check if the current size of the AddressBook is still less than the maximum size
- 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
- 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 you create
- 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)
