Reminder using JOptionPane

Question

I am designing one reminder type application using java swing.

In this I am giving two options to user, using JOptionPane YES_NO_OPTION. But what i want is if user not given any input within 10 minutes it should choose YES as default option.

what i have to do for that?

Please check below code...

public void snooze()
{
    int action = JOptionPane.showConfirmDialog(null, "Yes = close citrix and Aventail \n No = snooze after 30min", "Close", JOptionPane.YES_NO_OPTION);

    if(action == 0){

        killcitrix();
        endaventail();
        }

    else{
        JOptionPane.showMessageDialog(null, "Will snooze after 30min");

        try {
            TimeUnit.SECONDS.sleep(30);
        } catch (InterruptedException e2) {
            // TODO Auto-generated catch block
            e2.printStackTrace();
        }

        snooze();
    }
}

As user1803551 already mentioned, use a Timer. Here is an example:

1. after 10 seconds of inactivity (if the user didn't press any button), the dialog will automatically dispose and the selected option will be JOptionPane.YES_OPTION
2. If the user pressed 'No', a new JOptionPane with the same functionalities will appear after 5 seconds.
