Modern Art Generator (Java)

namarino · January 28, 2015

Hey guys. So I have an assignment that where I essentially have to generate random modern art. Theprogram generates either an oval or a rectangle and picks a color randomly from ones that I have chosen. But there's one part of the assignment that I don't quite understand. It says "the coordinates should be chosen based on the panel's width and height. Length of sides should be limited to half the width or height of the window." This is what I have so far. I'm just curious if I have interpreted those directions properly and if the program is behaving the way it should be. I'm having a hard time understanding the way shapes work in java. I really appreciate your help!
