Tuesday (10/6/09)

Warmup:

  • Upload AddressBook.java and AddressBookMain.java to SchoolWebLockers
  • Demo SelectionSort.java to Mr. Bui
  • Turn in your Dossier idea sentence

Agenda:

  • Introduction to Bubble Sort
  1. Initialize the front to be the top or beginning of the array
  2. Now go to the bottom/end of the array
  3. Compare the two adjacent elements to see if they are in proper sequential order
    1. Swap the elements if they are out of order (bigger number to the left of smaller number)
  4. Move to the next pair of adjacent elements/numbers
  5. Repeat steps 3 and 4 until the smallest number has "floated" to the top/front
  6. After you traverse the entire array
    1. Move the front so that the sorted numbers are ignored
    2. Go back to the end of the array
    3. Repeat steps 2 through 6 for the unsorted part of the array
  • Bubble Sort Animation
  • 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 or at the beginning of class tomorrow
  • Introduction to Program Dossier

Homework:

Wednesday (9/30/09)

  3. Repeat Steps 1&2, but ignoring the sorted front

Back to School Night

Monday (9/28/09)

Warmup:

  • Create a Java program called ArrayWarmup
  • Declare and initialize an int array of 10 numbers (I don't care what)
  • Write a for loop that traverses the array and prints all the numbers out

Agenda:

Thursday (9/24/09)

Homework:

Tuesday (9/22/09)

  • College Presentation with Ms. Settlemyer

Friday (9/18/09)

Warmup:

  • Demo your Person and Car classes to Mr. Bui

Agenda:

Homework:

Wednesday (9/16/09)

Warmup:

  • Complete the Circle class with the following methods:
    • Circle()
    • getRadius()
    • setRadius()
    • getDiameter()
    • getArea()

Agenda:

Homework:

Monday (9/14/09)

Warmup:

  • Be sure that you have completed the Hello, world Java programs from last week

AddressBookMenu Warmup

  • You will be creating a user interface menu for use with your AddressBook
  • Open / create your AddressBook's main method
  • 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:
(a)dd to address book
(p)rint address book
(q)uit

What would you like to do?
  • You should prompt for input after the menu is printed. Review Media:JavaIOExample.java for examples of input/output
  • If the user inputs 'a', then print a message that says "USER SELECTED ADD"
  • 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:

Homework:

Thursday (9/10/09)

  1. Write a Hello, world! program ( Hint: Java program template )
    1. Create a new Java program using JEdit or whatever editor you prefer
    2. Use the Java program template as a guide
    3. Insert your code
    4. Compile and execute your code
      1. Open terminal
      2. Navigate to your Java file
      3. javac FILENAME
      4. Execute your code: java PROGRAM_NAME
  2. Write a program that prints Hello, world 20 times (You may login to eimacs to remember how)
  3. Write a program that prints Hello, world infinite times

Tuesday (9/8/09)
