== Thursday (9/30/10) ==
'''Warmup:'''
* Pickup 5 playing cards from Mr. Bui
* Use the SelectionSort algorithm to hand-sort the cards from least to greatest

'''Agenda:'''
* Turn in field trip slips
* Turn in quiz corrections
* Demo [[AddressBook class lab assignment]]
* Demo ArrayPractice exercises
* Demo SelectionSort
* Add a (s)ort option to your AddressBook
** In order to compare Strings:
<source lang="Java">
if (str1.compareTo(str2) < 0)
{
System.out.println(str1 + " goes before " + str2);
}
</source>
* So inside your AddressBook, you'd have something like this:
<source lang="Java">
if (myContacts[i].getLastName().compareTo(myContacts[j].getLastName()) < 0)
</source>

== Back To School Night (9/29/10) ==
* [[Media:B2snIBCS2.ppt]]

== Tuesday (9/28/10) ==
'''Warmup:'''
* Create a Java file with a main() called SelectionSort
* Create an array of 20 ints
* Use your own numbers in the array

'''Agenda:'''
* Introduction to Selection Sort
# Find the smallest element
# Move to the front of the array (swap with front)
# Repeat Steps 1&2, but ignoring the sorted front
* [http://www.cs.oswego.edu/~mohammad/classes/csc241/samples/sort/Sort2-E.html Selection Sort Animation]
* [http://www.cs.ust.hk/faculty/tcpong/cs102/summer96/aids/select.html Another Selection Sort Animation]
* [http://math.hws.edu/TMCM/java/xSortLab/ Sorting Animations]
* Download [[Media:SelectionSort.java]]
** Fill in the commented parts of the SelectionSort.java file. Where there is a comment, you need to write code.

== Friday (9/24/10) ==
'''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
* Demo all assignments

'''Homework:'''
* Install the [http://www.oracle.com/technetwork/java/javase/downloads/jdk6-jsp-136632.html Java JDK] on your computer (be sure to choose your corresponding operator system)
* Install [http://www.eclipse.org/downloads/packages/eclipse-classic-360/heliosr Eclipse Classic] on your computer (be sure to choose your corresponding operator system on the right)
* Test it out, and let Mr. Bui know if you run into problems

* Array practice activities
*# Create a new Java class named ArrayPractice1. Create an array of 10 Strings (Use names of students in the room). Using a for loop, print out all the Strings in the array.
*# Create a new Java class named ArrayPractice2. Create an array of 10 integers (make a bunch of numbers up). Using a for loop and an if statement, print print out only numbers greater than 10.
*# Create a new Java class named ArrayPractice3. Create an array of 10 integers. Using a for loop, calculate the sum and average.
