JOptionPane.showInputDialog auto exit

Question

With this,

JOptionPane.showInputDialog(null,"Enter Your Name");

I'd like the user input dialog box to auto exit. I mean within 2 or 3 seconds only show that JOptionPane user input dialog and close after that. It should automatically close that input dialog box only, not the whole program. The System.exit(0) method causes the full program to exit, but I want only close that input dialog box not full program. Then I want only Swing input dialog not message box and confirm box.

Why on Earth would an app. limit the time to `Enter Your Name` to just 2-3 seconds?!? — Andrew Thompson, Jun 07 '17 at 06:37

As shown in How to Make Dialogs, you can add intercept Automatic Dialog Closing in a PropertyChangeListener. Based on this example, the variation below adds a label, prompt, and text field to the option pane. A Swing Timer counts down from TIME_OUT, updating the label each time. The PropertyChangeListener dispatches a WINDOW_CLOSING event when the OK button is pressed or time runs out.

import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowEvent;
import java.beans.PropertyChangeEvent;
import java.beans.PropertyChangeListener;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JTextField;
import javax.swing.Timer;

        timer.restart();
