Hi there,
I have an assignment due in a couple of days and I need some help. I don't have time to read a Java books. Plus, my teacher is useless as he can't explain anything...and the TAs are worst. My error is in line 145 (scroll down) saying "illegal start of expression". I didn't have this error before I added the movement command. Any help is greatly appreciated :)

Please use code-tags and proper indentation.

I believe you meant to close your while loop and your run method before overriding paint--

Thanks :):)

However, I can't get the oval, oval2, neck, eye, eyes to move up and down. I'm using the code my instructor gave me and it isn't that helpufl :S

It's considered bad form to post verbatim threads on two separate forums at the same time. Read post 4 on the other forum, in particular. It may well be true that your instructors/T.A.'s aren't very good, but generally it's a bad idea to mention it, as well as mentioning that you don't have time to read the book. Saying you can't get something to work also doesn't help much, particularly since you haven't posted the revised code.

Close this thread or the other thread on the other forum, ask a more specific question, and don't wait till a few days before it's due next time.
