Optional<String> result = dialog.showAndWait();
String s = result.map(r -> {
try {
Integer n = Integer.valueOf(r);
return MessageFormat.format("Nice! I like {0} too!", n);
} catch (NumberFormatException ex) {
return MessageFormat.format("Unfortunately \"{0}\" is not a int!", r);
}
}).orElse("You really don't want to tell me, huh?");
System.out.println(s);
