PWC Java Course 06/12/06
Posted by jfalkner on June 12, 2006 at 6:18 AM PDT This is reference page for the Java course I taught for PWC. We'll put links and notes here for things that we talk about in the course. You can also leave comments for anything that I miss.
Links for the tools that we use.
- Java Development Kit (JDK) 5.0: This is the code that will compile and execute Java. Remeber to set your classpath to include the "/bin" directory and you may have to include the "-cp ." flag when running code.
- Netbeans IDE: This is the tool that we used to develop code. You can also download the profiles from here.
- JavaDocs: Your best buddy when programming. This code comes with "the Java platform" and it can make life easy when coding. Knowing what classes exist in the JavaDocs and how to use them is what makes for a great Java programmer.

- Rock, Paper, Scissors Challenge
- RockPaperScissorsChallenge.zip
- Rock, Paper, Scissors Snapshots of Opponent's Code
- Tuesday's Challengers: This JAR file includes the compiled code for the players on Tuesday. We won't look at the source-code until Friday. Here are the player names so that you can add them to your local tournment.
"rockpaperscissorschallenge.JoeTuesday",
"rockpaperscissorschallenge.JoeZinziTuesday",
"rockpaperscissorschallenge.JaysonWalkerTuesday",

- Wednesday's Challengers: This JAR file includes the compiled code for the players on Wednesday. We won't look at the source-code until Friday. Here are the player names so that you can add them to your local tournment.
"rockpaperscissorschallenge.wednesday.Joe",

Friday's Challengers + Jayson's Learning Player: This is the final JAR file for Friday's code. Congrats to Joe Zinzi for coming out with the best code. You'll have to also include Thursday's JAR and the players from the original challenge code in order to include all the players in the list.
I've included one more player: LearningRockPaperScissors. This player learns how to play based on how everyone else is playing -- behold the power of static variables! You'll note that this code wins 60% of the time after 1,000 tournaments, 75% of the time after 10,000 tournaments, and 80%+ of the time with 100,000 tournaments. It seems to handily beat any hard-coded strategy. Take a peek at the code. I've e-mailed it to everyone in the class with the final source-code ZIP.
