The problem with that is that if there is an empty space in the JTextField, ParseInt displays an error, and the program crashes. So, I was thinking of skipping the int conversion part.
You must use Integer.parseInt() on JTextField(s) content in order to do what you want.
Note that parseInt throws NumberFormatException if the input is not valid (the given string cannot be parsed into integer value), so you can use it to validate user's input before doing what you want to do with those integer values.
