Java assignment help
Posted: Nov 9, 2008 1:31 PM

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
