Hello. I was wondering if we could go over the Lab 4.6 in class? I am trying to follow the textbook directions for the lab, but I am getting very confused. 

For example, when the book says to remove all methods of "RoundBalloon.java" except for "draw", I am confused because I could not find a pre-existing method named "draw" in the "DrawBalloon" file that the lab is based off of. Additionally, wouldn't that also mean removing the main method, which would result in an error (my program now says it is missing a main method). Because of this, I have been stuck so I have not gotten a chance to continue onto further steps.  I have also tried to restart multiple times, but I still cannot figure it out. 

Thank you for your help!
