Warmup:
- Assume you have the following code:
a = 3
b = 5
System.out.println("a = " + a);
System.out.println("b = " + b);
//swap the values in the variables here
System.out.println("a = " + a);
System.out.println("b = " + b);
Agenda:
- Add a (s)ort option to your AddressBook
- In order to compare Strings:
if (str1.compareTo(str2) < 0)
{
System.out.println(str1 + " goes before " + str2);
}
- So inside your AddressBook, you'd have something like this:
if (myContacts[i].getLastName().compareTo(myContacts[j].getLastName()) < 0)

- 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
- Sorting Animations
- Another Selection Sort Animation
- Another Selection Sort Animation
- Download Media:SelectionSort.java
- Fill in the commented parts of the SelectionSort.java file. Where there is a comment, you need to write code.
- Demo SelectionSort

Wednesday (9/12/12)
Agenda:
- Demo Media:CombatSimulation.java
- Review Arrays
- Array practice activities. Create a new Java class named ArrayPractice
- 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 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 an array of 10 integers. Using a for loop, calculate the sum and average.
- Demo ArrayPractice
- AddressBook beginning walk-through
