How would i get this code to display graphical user interface (GUI) using JOptionPane. ive been trying to do it but when i try to display the outputs like the tax information and calculations but for the tax inforamtion it gives me zeros and for the names after putting it into the GUI and gives me the output it shows up as null. or now just gives me a blank screen with no information.
