Questions on HW3-Spring07

Question: Is our homework now due on Mondays at 10, or was that just the first assignment (so it's still due Friday at 7)?

Question: Where is the blockingplay() method? It is not in the Sound Samples.

Question: for this homework we are going to write long code something like
pete-turtle on world
pete.square(30); c4.blockingPlay(); pete.forward(100); e4.blockingPlay().....???

Question: Just to clarify, are sampled sounds the sounds that are in .wav files in our mediasources folder? If not, I am confused as to what sampled sounds are.

Question: Can we use sound files other than the ones in the MedisaSources Folder??? I assume we do but I was not sure.

Question: When we are using midi, how do we write two notes playing at one time? For example, you need to write chords with piano music, and I would like for the chords to be played on one part, instead of having multiple parts with one note for each beat.

Question: What happens if your computer can't run it b/c there is not enough memory?

Question: Sometimes when I run my Turtle Dance, I get an error that says something like "Exception in thread...Concurrent Modification...". It doesn't happen all the time, which is weird. What is it?

Question: Is there a way to make the background color of a world something other than white?

Question: For the hw, it says implement it in a main method. So I just wanted to clarify, is a main method something similar to what we did in hw 2 for example, we defined our class and then wrote:
static public void main()
I was just wondering if this is what defines a main method.

Question: Why is Dawn answering all these questions when she should be busy at work?

Question: What are "the other ways" of making the turtle dance w/ music ?

Question: I can't remember, what is the way to get access to the table that shows all the notes and their respective JMC notation?

Question: Do you want us to show the turtle, or is it enough to just drop a picture? Does the turtle have to be visible?

Question: Frame Sequence keeps giving me the following warning
File: C:\Documents and Settings\Leflor\My Documents\Programs\java-source-Fall06\ [line: 161]
Warning: C:\Documents and Settings\Leflor\My Documents\Programs\java-source-Fall06\ warning: [unchecked] unchecked call to add(E) as a member of the raw type java.util.List

And when I run my code a pointer is returned as null so it just stops running before it gets to play the video, I get frames no moving imagery in front of me though.

Question: When I try to compile one of the example files like the very first line: import; is highlighted. The error reads
Error: C:\Documents and Settings\Owner\Desktop\cs1316\java-source-Fall06\java-source-Fall06\ package does not exist
do i have to set a path or something?
but I already have a path to jmusic set up in preferences.
my jmusic.jar isn't actually inside the inst folder though. its right in the top layer of the jmusic folder. should the path be directly on the .jar file?
much obliged Dawn. it works now.

Question: I've put my whole code in order and it looks right and compiles correctly and even runs, but the sound does not play in the place I put it in. I have a while loop so the turtles spin for a while and even though the sound is placed higher above the while loop the music still plays after. tell me why!

lol my problem is that the turtles don't show up, although I have the blank world come up. instead of doing; which gives me an error message I did the names of my turtles:; etc...
