Answer 1

"if(true)" will always be true and it will never make it to the else. If you want it to work correctly you have to do this:

int reply = JOptionPane.showConfirmDialog(null, message, title, JOptionPane.YES_NO_OPTION);
if (reply == JOptionPane.YES_OPTION) {
    JOptionPane.showMessageDialog(null, "HELLO");
} else {
    JOptionPane.showMessageDialog(null, "GOODBYE");
    System.exit(0);
}

Answer 2

Something along these lines ....

   //default icon, custom title
int n = JOptionPane.showConfirmDialog(null,"Would you like green eggs and ham?","An Inane Question",JOptionPane.YES_NO_OPTION);

String result = "?";
switch (n) {
case JOptionPane.YES_OPTION:
  result = "YES";
  break;
case JOptionPane.NO_OPTION:
  result = "NO";
  break;
default:
  ;
}
System.out.println("Replace? " + result);
