Friday (9/30/11)
Agenda:
- Sorting Quiz
- Introduction to Abstract Data Type (ADT)
- Introduction to Data Structures
- Stacks
- Stack Practice
- After studying the stack code, you will attempt to re-create the Stack.java code
- Create a new Java project called StackPractice
- Download Media:EmptyStack.java
- Rename EmptyStack.java to Stack.java AND add it to your StackPractice project
- Download Media:StackMain.java and add it to your StackPractice project
- Fill in the code for all the empty stack methods
- Test your own stack code with StackMain.java
Homework:
- Analyzing the Problem due Tuesday (10/4/11)
- Quick Stack Quiz on Tuesday (10/4/11)
Wednesday (9/28/11)
Warmup:
- Repeatedly comparing adjacent elements and swapping them so that they are in the correct order. Which sort am I?
- Repeatedly look for the smallest thing currently in the collection and putting it aside. Which sort am I?
Agenda:
- If you have no missing assignments, complete the optional survey.
- Insertion Sort
- From the very beginning...insert the value into the correct spot (there may need to be some shifting around)
- Quick Sort
- Start with a partition (will be the entire list in the beginning)
- Pick an element at random. It will be the pivot value.
- Go through the list and values less than the pivot are put before it and values greater than the pivot will come after.
- The pivot also partitions the list into two sublists. Repeat steps 1-4 for each of the sub-lists.
- Sorting Animations
- Quicksort
- Sorting Quiz this Friday (9/30/11)
- Be able to explain each of the sorts
- Work on your Analysis of the Problem
- Demo missing assignments
Homework:
- Sorting Quiz this Friday (9/30/11)
- Analyzing the Problem due Tuesday (10/4/11)
Back to School Night (9/26/11)
Monday (9/26/11)
Agenda:
- SelectionSort Review
- Demo SelectionSort.java
- Demo the sort option added to your AddressBook
- Introduction to Bubble Sort
- Initialize the front to be the top or beginning of the array
- Now go to the bottom/end of the array
- Compare the two adjacent elements to see if they are in proper sequential order
- Swap the elements if they are out of order (bigger number to the left of smaller number)
- Move to the next pair of adjacent elements/numbers
- Repeat steps 3 and 4 until the smallest number has "floated" to the top/front
- After you traverse the entire array
- Move the front so that the sorted numbers are ignored
- Go back to the end of the array
- Repeat steps 2 through 6 for the unsorted part of the array
- Sorting Animations
- More Sorting Animations
- Download Media:BubbleSort.java
- Fill in the commented parts of the BubbleSort.java file. Where there is a comment, you need to write code.
- Demo to Mr. Bui at the end of class
- Introduction to the Program Dossier
- Media:CriterionA1_problemAnalysis.doc
- Analyzing the Problem due Tuesday (10/4/11)
- Work on your Analyzing the Problem section
Homework:
- Any leftover AddressBook demonstrations (including a sort option)
- SelectionSort and BubbleSort
- Analyzing the Problem due Tuesday (10/4/11)
Thursday (9/22/11)
Warmup:
- Form a group of 3 people
- Receive several playing cards from Mr. Bui
- Shuffle the cards
- Sort them in numerical order by repeatedly finding the smallest card and separating it
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
- Selection Sort Animation
- Another Selection Sort Animation
- 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.
- Demo SelectionSort
- 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)
Friday - Tuesday (9/16/11 - 9/20/11)
Warmup:
- Download Media:ConsoleInput.java
- Download Media:ConsoleInputExample.java
- Create a new Java project to test out ConsoleInput
Agenda:
- Return Software Development Quizzes
- Corrections for 1/2 partial credit (Turn in corrections by the end of the week)
- Complete AddressBook class lab assignment by the end of class
Wednesday (9/14/11)
Warmup:
Agenda:
- Java Review?
- How does it all work?
- Create Java Classes (object blueprints)
- Create a separate main class with a main method. The main method can use other objects defined in classes.

- Car class lab assignment - Complete in 5-10 minutes
- CodingBat - Java - Practice!
- Review Arrays
- 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.
