Questions? Comments!


Inquiring minds need to know!


love java. want to learn more about the variations of "main", static", "class", "extends" and "void" in each program to labels classes and the methods.
will we be learning how to use the Java API on the sun site? this would be awesome going into 1322.
Yes, we'll learn more about how to use the Java API, and we'll be talking about the variations of the Java buzzwords. If you want to do more Java before data structures, we are building a textbook that covers the same computer science and media as CS1315, but is all in Java. You can download the book at http://coweb.cc.gatech.edu/mediaComp-plan/101, if you'd like some additional Java with media computation resources. I have three favors to ask with respect to use of this book, though:
  1. If there are things that you don't understand that lead you to dive into the Java book, please let me know! I want to make sure that the course notes and slides for CS1316 stand on their own, and that 1316 students won't have to buy the Java media computation book, too.
  2. If you find any bugs, please put them on the bugs list on that page! One of the tough parts of writing the Java mediacomp book is that we don't have a GT class using it, so we don't get the same level of feedback. (It's being used at other places – see http://coweb.cc.gatech.edu/mediaComp-teach)
  3. If you use the Java book and like it or have suggestions about it, please put the comments on the Suggestions page there. Again, we're not getting as much feedback about this book, so we could use both positive and negative responses – what's working and what's not.
THANKS! Mark Guzdial

is it possible to run dr. java on linux?
Absolutely! Go check out the drjava site and download the jar file instead. See me in class to give you commands to type to run it from there. Mark Guzdial

Great. thank you.
Oh REMOVEDux User: I didn't hear from you, but here's how I do it. (I actually run the .jar file on my Windows box.)
java -jar ./drjava-stable-20040326.jar

Folks were asking in class how to blend pictures. Here are the pages from the CS1315 book on how that works: OnBlendingPictures.pdf Mark Guzdial
I think I found something that needs correction: on the bottom of page 16 in the Latest Course Notes, it says "FileChooser.setMediaPath("D:cs1316mediasources");" There should be a path deliminator after the last "s" in sources, and another one right after "D:". I encountered problems when I copied verbatim from the text. So, basically -> "D:/cs1316mediasources/" works. If the deliminator after "...mediasources" isn't included, it messes up your attempt at defining the file correctly. For example, when I tried x.show(), the viewer box opened up and gave me an error message. I got scared and cried.

Thanks, Tom! (Sorry you cried!) I'll work on that. (I think LaTeX bit me.) Mark Guzdial

Note! Quiz will be at the START of class Wednesday!
