AP CS Summer 2008

Welcome to
AP Computer Science!

Goals for today:

get acquainted - download
and fill out this questionaire
ask a few "big questions"
set up BlueJ
watch a movie and make the
obligatory "hello world"
program in java
take a break
talk about program design
complete lab 1: bike wattage
program, the console version

To work at home (hopefully you won't
have to), you'll need BlueJ on your
home computer. Here's a movie that
will help you get set up at home.

More fun with java!

Goals for today:

Mr. Franke's next movie will guide you through making a graphical application out of your Bike Wattage program -- watch the movie and follow along with BlueJ
Take a break
At 10:30 we'll talk about Karel
Here's a video that will help
you get started with Karel
Complete Lab 2: H-Bot
Complete Lab3: Handoff-Bot
Learn how to load worlds and how to make new methods
Do Lab 4: ArrangeBot
with this world
Do Lab 5: Stair Sweeper
with this world

Hands-on with Karel

Continue where you left off with

Lab 4: ArrangeBot
using this world
Lab 5: Stair Sweeper
using this world

Next we'll talk about polymorphism
and begin work on

Lab 6.1: Harvester
using HarvesterWorld
Lab 6.2: DiamondHarvester
using DiamondField.kwld

Extra Credit problem: PlanterBot
using this world.

Fun with Polymorphism

Continue with yesterday's tasks. (Click on the 25th in the calendar to get at what we did yesterday).

If you are done, try this challenge. You'll have to download this BlueJ project and this world.

Mr. H is going to introduce you to Boolean functions and conditional (a.k.a. "if") statements. Here's a list of what the new and improved Robot can tell you.

Extend your Harvester and DiamondHarvester classes so they can harvest sparseField.kwld and sparseDiamond.kwld

Do Lab 7.1: Hurdle Racer and test it on these worlds: hurdles1.kwld and hurdles2.kwld

Time to Recurse

Continue work you began yesterday. We will touch base with you to see what you have finished.
Introduction to recursion
Create a SuperBot (Lab 8)
Do Lab 9: RelayBot
Using arguments
Do Lab 10. You will need:
fieldBig1.kwld & fieldBig2.kwld
stairsBig1.kwld &stairs Big2.kwld
hurdlesBig1.kwld & hurdlesBig2.kwld

Have a good weekend!

a-MAZE-ing Robots

Here are some interesting problems to begin working on (Lab 11). Here is a zip file of worlds to test your solutions.

Class Discussion:

another polymorphism example
passing information to methods
overloading methods
methods that return values
test review

Make your SuperBot even more super

Be prepared for a test tomorrow!

Test 1

Keep working on the problem set from yesterday.

At 10:00 we'll take a short test.

Polymorphism Review

We're going to sit down together, go over the basic concepts of polymorphism, and look at some examples. As part of this, we'll look at the exam, although they aren't finished being marked.

Then you should go back over all your programs that use SuperBot, and rewrite them using good programming techniques.

Work Day

Continue working on revising
Labs 10-11, making sure to use polymophism correctly.

Exam review mid-morning.

Reminder: no class tomorrow!

Have a nice weekend!

No Class

Enjoy the weekend!

Javadoc and Loops

First we'll talk about documenting classes using Javadoc. Here's How to Write Doc Comments for the Javadoc Tool.

Document your SuperBot completely.

Then we'll learn about

looping statements
member variables

Change your SuperBot so that it uses member variables to keep track of where it is and how many beepers it has in its bag. What methods will you have to change? Do you have to change the documentation?

SuperBot Exercises

Extend your SuperBot in the following exercises:

Lab 13: Decoding & Encoding
part 1: decoding
here are some worlds to decode
part 2: encoding
Lab 14: Avoiding Walls
start your robot at (5,5)
part 1: world1, world2, & world5
part 2: world3, world4, & world5

More Java

Review of passing parameters and returning values.

Work on Lab 14: Avoiding Walls
start your robot at (5,5)
part 1: world1, world2, & world5
part 2: world3, world4, & world5

Games and A.I.

Today we'll explore some games that computers can play. Working in pairs, you'll program Karel to play a couple
of these games against a human opponent.

Karel Games

Finish NimBot

Super Challenge: see if you can make a simple game of tic-tac-toe using Karel. Start with just making a user interface that accepts input from 2 human players. Your user interface can use either the console (easier) or a graphic user interface (harder), maybe with multiple buttons (hardest).

More Java

0. Introductions (for the benefit of Mr. Franke).

1. Discuss Game of Nim Design

2. Sort out your life

3. Final Karel Project: Sorting Bot

4. Your Second Sip of Java - Swing Components.

More Java

0. Finish/improve SortingBot. If it sorts properly, try modifying classes to use fewer robots.

1. Your Second Sip of Java, with Squint

2. The world of JComponents: JButton, JTextField, JTextArea, JComboBox, JLable, JPanel, and more!

3. A windowed version of Nim?

Networked Java

Today we will improve our email programs and invent our protocols to provide a network service.

1. Double-check basic email sending is working.

2. Improve your email client, by adding text fields to accept an address, CC, subject, etc. --we'll discuss how to properly format your message to do this.

3. Making a server - MATH SERVER

4. Make a simple transactional game server, client, etc.

5. Make a chat server.
