    {                                   
        int confirmed = JOptionPane.sh         


        

Answer 1

From what i understand you want something like this

addWindowListener(new WindowAdapter() {
  public void windowClosing(WindowEvent e) {
    int confirmed = JOptionPane.showConfirmDialog(null, 
        "Are you sure you want to exit the program?", "Exit Program Message Box",
        JOptionPane.YES_NO_OPTION);

    if (confirmed == JOptionPane.YES_OPTION) {
      dispose();
    }
  }
});

If you want to use it on some button do similiar function to button. Put listener on it and do same. But I'm not sure if I get your question right. But If you want to use button use ActionListener and action performed method.
