Assignment due in 4 hours, what is wrong with my code? Supposed to write a program that allows a user to selected their desired pizza and the total will be produced. I have errors more towards the adding all of my check boxes and labels to my panel. Please explain what I am doing wrong. Thank you! The addItemListener and below are potentially incorrect.
