Example demonstrating how to get the return value from a confirm dialog.

JOptionPaneExample.java

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class JOptionPaneExample
{
    public static void main(String [] args)
    {
    	int returnValue = 0;
    	returnValue = JOptionPane.showConfirmDialog(null, "Are you sure you want to exit?", "Are you sure?", JOptionPane.YES_NO_OPTION);
    		
    	if (returnValue == JOptionPane.YES_OPTION)
    		JOptionPane.showMessageDialog(null, "Yes was clicked.");
    	else if (returnValue == JOptionPane.NO_OPTION)
    		JOptionPane.showMessageDialog(null, "No was clicked.");
	}//End of main method
}//End of class

Thanks!
