How to change the text of yes/no buttons in JavaFX 8 Alert dialogs

Question

I have this code snippet:

Alert alert =          new Alert(AlertType.WARNING,              "The format for dates is year.month.day. " +             "For example, today is " + todayToString() + ".",              ButtonType.OK,               ButtonType.CANCEL); alert.setTitle("Date format warning"); Optional<ButtonType> result = alert.showAndWait();  if (result.get() == ButtonType.OK) {     formatGotIt = true; } 

Above, I request two buttons titled "Yes" and "No." However, I wish to change them both.

You can define your own button types. In this example the buttons' text is foo and bar:

ButtonType foo = new ButtonType("foo", ButtonBar.ButtonData.OK_DONE); ButtonType bar = new ButtonType("bar", ButtonBar.ButtonData.CANCEL_CLOSE); Alert alert = new Alert(AlertType.WARNING,         "The format for dates is year.month.day. "         + "For example, today is " + todayToString() + ".",         foo,         bar);  alert.setTitle("Date format warning"); Optional<ButtonType> result = alert.showAndWait();  if (result.orElse(bar) == foo) {     formatGotIt = true; }
