I'm having an issue with a project in my CS class. I am writing a 6 part program to which I am stuck on part 4. Here are the instructions I have received from my professor. CS 1713: Project 1 for Spring 2011 On this part I can't seem to figure out why the hitLeftWall and hitRightWall method is not being called from the physics class. I am including all 5 of my classes in a zip file so it may be reviewed I appreciate it very much. Thank you for your assistance if any.
