So, I've read the Java API, but still can't seem to make heads or tails about how to do this. And believe me I have tried. I want an ActionListener to cause a message box with the text 'Do you really want to exit?', with options yes and no which exits the program or not depending on the selected button.
Here's what I have for the ActionListener before I started to break it with the message box:
exitItem.addActionListener(
new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
window.dispose();
}
}
);
How can I suitably change it to meet my requirements?

Try this..
JOptionPane.showConfirmDialog(null, "Do you", "Message",
JOptionPane.YES_NO_OPTION);
It will return 0 for Yes and 1 for No

I think you want to do something like this inside your ActionListener
:
int selectedOption = JOptionPane.showConfirmDialog(null,
"Do you wanna close the window?",
"Choose",
JOptionPane.YES_NO_OPTION);
if (selectedOption == JOptionPane.YES_OPTION) {
window.dispose();
}

final JOptionPane optionPane = new JOptionPane(
"The only way to close this dialog is by\n"
+ "pressing one of the following buttons.\n"
+ "Do you understand?",
JOptionPane.QUESTION_MESSAGE,
JOptionPane.YES_NO_OPTION);

not clear what do you really want to do, maybe
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class ClosingFrame extends JFrame {
private JMenuBar MenuBar = new JMenuBar();
private JFrame frame = new JFrame();
private static final long serialVersionUID = 1L;
private JMenu File = new JMenu("File");
private JMenuItem Exit = new JMenuItem("Exit");
private JFrame frame1 = new JFrame();
public ClosingFrame() {
File.add(Exit);
MenuBar.add(File);
Exit.addActionListener(new ExitListener());
WindowListener exitListener = new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
int confirm = JOptionPane.showOptionDialog(frame,
"Are You Sure to Close this Application?",
"Exit Confirmation", JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE, null, null, null);
if (confirm == JOptionPane.YES_OPTION) {
System.exit(1);
}
}
};
frame.addWindowListener(exitListener);
frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
frame.setJMenuBar(MenuBar);
frame.setPreferredSize(new Dimension(400, 300));
frame.setLocation(100, 100);
frame.pack();
frame.setVisible(true);
frame1.addWindowListener(exitListener);
frame1.setDefaultCloseOperation(EXIT_ON_CLOSE);
frame1.setPreferredSize(new Dimension(400, 300));
frame1.setLocation(500, 100);
frame1.pack();
frame1.setVisible(true);
}
private class ExitListener implements ActionListener {
@Override
public void actionPerformed(ActionEvent e) {
int confirm = JOptionPane.showOptionDialog(frame,
"Are You Sure to Close this Application?",
"Exit Confirmation", JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE, null, null, null);
JOptionPane.showMessageDialog(null, "Whatever", "Whatever",
JOptionPane.ERROR_MESSAGE);
int confirm1 = JOptionPane.showOptionDialog(frame1,
"Are You Sure to Close this Application?",
"Exit Confirmation", JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE, null, null, null);
if (confirm == JOptionPane.YES_OPTION) {
System.exit(1);
}
}
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
ClosingFrame cf = new ClosingFrame();
}
});
}
}
