alert.setTitle("Current project is modified");
alert.setContentText("Save?");
ButtonType okButton = new ButtonType("Yes", ButtonBar.ButtonData.YES);
ButtonType noButton = new ButtonType("Yes", ButtonBar.ButtonData.NO);
ButtonType cancelButton = new ButtonType("Yes", ButtonBar.ButtonData.CANCEL_CLOSE);
alert.getButtonTypes().setAll(okButton, noButton, cancelButton);
alert.showAndWait().ifPresent(type -> {
if (type == ButtonType.OK) {
} else if (type == ButtonType.NO) {
} else {
}
});

Hi, theres couple of mistakes.
1) All buttons marked as Yes... Yes Yes Yes. Need to assign different captions. "Yes, shure" "No no no" "It does not matter"

ButtonType okButton = new ButtonType("Yes, shure", ButtonBar.ButtonData.YES);
ButtonType noButton = new ButtonType("No no no", ButtonBar.ButtonData.NO);
ButtonType cancelButton = new ButtonType("It does not matter", ButtonBar.ButtonData.CANCEL_CLOSE);

2) when You process result do use declared objects (not standard types):

alert.showAndWait().ifPresent(type -> {
if (type == okButton) { // do something
} else if (type == noButton) { // do something
} else { // do something
}
});
