Got a JOptionPane which contains a 'Continue' button and a 'Close procedure' button. How do i handle these buttons in a if / else statement,

A variety of dialog boxes can be displayed using the JOptionPane class. Two of the dialog boxes are: Message Dialog - a dialog box that displays a message. Input Dialog - a dialog box that prompts the user for input.

So if you click continue , nothing will happens in the if, but if you click 'close procedure' it much runs the code i have written.

my code so far:

You should use n to compare, as you store the result in there.
