Pop up warning if user inputs the number 0

So i have that program that i sell. The program produces text and calculations in a sentence based on user inputs. But if a user inputs 0 in some boxes java produces some very weird calculations because that means it is dividing by zero.

So basically i just need a warning kinda heads up for the user whenever he enters 0 in one of these boxes.

Should be super easy. I have attached some of the code so you can get an idea of how its made.
