NEWBIE: How to end JOptionPane?

Dear Experts,

I just popped a JOptionPane (thanks, CEHJ!) into a class.  Works beautifully, but after I click "Yes", and the box goes away, and my class would otherwise end, it does not end.  I'm assuming I have to explicitly kill the JOptionPane thread, but I don't know how?  (I'm running it inside of Eclipse.)

This is the code snippet:

Object[] options =
{
"Yes", "No"
};
int n = JOptionPane.showOptionDialog(null, "Some Question? "
                        , "Some Title", JOptionPane.YES_NO_CANCEL_OPTION,
                        JOptionPane.QUESTION_MESSAGE, null, options, options[1]);

return n;


Thanks again,

Do you have a JFrame?

No.  (AFAIK.)  This is just an internal tool, to I'm using NULL for the frame, and it's then popping up inside of Eclipse.  If there is no easy solution here, that's fine.  I can always kill it manually...

This is a common thing. JOptionPane does this all the time :)

Try it out *outside* Eclipse first to see if it's really a problem

i have seen this problem before....
and I was on UNIX csh....

It is similar to a JFrame being .hide() instead of System.exit(0).

you need to use System.exit(0) as SamsonChung suggested above.
