//CONFIRMATIONダイアログ生成
Alert alert = new Alert(AlertType.CONFIRMATION);
//DaialogPaneの各領域に値を設定
alert.setTitle("Confirmation Dialog");
alert.setHeaderText("Look, a Confirmation Dialog");
alert.setContentText("Are you ok with this?");

//Alertダイアログなので、戻り値はOprtional<ButtonType>

    // ... user chose CANCEL or closed the dialog
