I want to close a JOptionPane whenever the user types in 0 or -1. I have currently set up a boolean variable and assigned it a value of false. When the user types true, I want the window to close. However, I am not sure of a method which will close JOptionPane after the sentinel value is typed. Is there a way to do this?

generally, that's not how a JOptionPane works i.e. the entry closing it.

the 0/-1 sentinel value is usually associated with a while()


is this something like what you're trying to do?

If you have a reference to your JOptionPane object, you can use its setValue method. For default options, you need an Integer object with JOptionPane.OK_OPTION to simulate an OK press.
