If you downloaded it before this, can you please re-download CritterMain.java, recompile it, and try again to run it? Thanks, and sorry for my mistake.

We recommend that you download and use this newer version of DrawingPanel because it animates more smoothly. (The old one will still work.)

• HW4 creative output: The assignment spec shows the output your program must have. You should match this exactly, as usual. However, after this output, you are free to optionally put any additional output you like. (Follow the usual "creative output" constraints: Keep it under 100 lines or so, nothing hateful, no endless loops, no reading from the Scanner... just printlns, please.)

  For example, you could print a message about your own birthday and an interesting fact about that date, such as:

  Did you know?  Marty's birthday is on 9/19.
  9/19 is also International Talk like a Pirate Day.
  Arrr, me mateys!
  

  Here's an example output file that has this output at the end. Consider checking Wikipedia for an interesting fact about your birthday.

  • hw4_expected_output_1.txt

Homework 3 (Doodle / Circles): due Tuesday, October 16, 2007, 4:00pm.
No late submissions accepted after Saturday, October 20, 2007, 4:00pm.
Turn in Homework 3 here.

Note: Compare your output from within the DrawingPanel. Save the appropriate expected output image below to your disk. Then in the DrawingPanel, click File, Compare to File... and browse to select that image.

You do not need to achieve "0 pixels differ" in the comparison tool to get full credit. It is hard to get exactly the same image as ours because of subtleties about how shapes are painted. If there is no visible difference between your image and ours, you should get the full points.

Homework 1 (Song): due Thursday, October 4, 2007, 4:00pm.
Turn in Homework 1 here.

• hw1-song.pdf
• hw1-song_expected_output.txt
• song_excerpt.mp3

Please note: You'll probably have at least 3 files related to your song program:

• Song.java - the file you should turn in
• Song.java~ - a backup of your previously saved version
• Song.class - the compiled binary file

You should turn in Song.java, not the other two. In Windows, it might show up as just Song and not Song.java, because Windows sometimes hides certain file extensions. See the Working from Home section for a description of how to turn this off, if you're interested.
