'''Warmup:'''
 
−
* You will be creating a user interface menu for use with your AddressBook
 
−
* Open / create your AddressBook's main method
 
−
* Inside the main method, create an AddressBook variable:
 
−
 
 
−
<source lang="java">
 
−
AddressBook book = new AddressBook();
 
−
</source>
 
−
 
 
−
* 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:
 
−
 
 
−
<pre>
 
−
(a)dd to address book
 
−
(f)ind a Contact
 
−
(p)rint address book
 
−
(q)uit
 
−
 
 
−
What would you like to do?
 
−
</pre>
 
−
 
 
−
* You should prompt for input after the menu is printed.  Review [[Media:JavaIOExample.java]] for examples of input/output
 
−
*# Add '''import java.io.*;''' at the very top
 
−
*# Add '''private static BufferedReader stdin = new BufferedReader( new InputStreamReader( System.in ) );''' before main()
 
−
*# Add '''throws IOException''' so that main() reads like '''public static void main(String [] args) throws IOException'''
 
−
*# You may now use '''stdin.readLine();''' to read in a String
 
−
*# To compare Strings, use .equals() like so: '''myStr.equals("a")'''
 
−
* If the user inputs 'a', then print a message that says "USER SELECTED ADD"
 
−
* If the user inputs 'f', then print a message that says "USER SELECTED FIND"
 
−
* 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"
 
−
 
 
−
'''Agenda:'''
 
−
* Complete [[AddressBook class lab assignment]]
 
−
* Create the '''Contact remove(String fn, String ln)''' method for the AddressBook
 
−
*# Using a for loop, find the Contact that matches fn and ln, and save it in a variable
 
−
*# Once you have found the Contact, you should remember its index (location) in the array
 
−
*# Check if the Contact was found in the array
 
−
*## If it was found, you must use a loop to shift all the array elements down one index
 
−
*## HINT: myContacts[i] = myContacts[i+1] //where i is a loop counter
 
−
*# Be sure to set the last element to null (so that there isn't a duplicate Contact in the end)
 
−
*#* HINT: myContacts[size-1] = null;
 
−
*# Decrement size
 
−
*# Return the removed Contact
 
−

 +
** General questions should be posted in the Canvas Discussion area; however, the student should check if any existing discussion threads already answer their question. If not, then a new thread should be created for their question
 +
** Specific questions about student code will require students to take a screenshot of their own code and message it to Mr. Bui. The Canvas messaging system will likely be used for this because Mr. Bui does not want his inbox to be flooded
