I agree and that is what I did at first I put the repaint() right after the color change like this

Thank you for the help. but now i'm confused on why this works. I called repaint which calls the paintComponent method but repaint is in the paintComponent method? so how does that work?

I thought Integer.parseInt(candyNum[i]) would change the string to a int?

I'm trying to fill an arraylist with number but I don't want the user to have to press enter after each number. I would like it if they could put all the numbers on one line separated by white space...

This is the right answer.

I think I been asking the wrong question. I knew how to get the information obviously since I did it in my first post. Sorry about that. but is there a way to convert that into a "date type" where I...

Thank you. I been looking up and down GregorianCalendar and the calendar API. But i don't see anything that will get the information from my constructor.
