private void registerListener1(TextField tf1, TextField tf2,TextField tf3,TextField tf4) {
    tf1.textProperty().addListener((obs, oldText, newText) -> {

        if(newText.length() == 12) {

            tf1.setText(newText.substring(0, 3));
            tf2.setText(newText.substring(tf1.getText().length(), 6));              
            tf3.setText(newText.substring(tf1.getText().length()+tf2.getText().length(), 9));
            tf4.setText(newText.substring(tf1.getText().length()+tf2.getText().length()+tf3.getText().length()));
            tf4.requestFocus();
        }
    });

}

private void registerListener(TextField tf1, TextField tf2) {
    tf1.textProperty().addListener((obs, oldText, newText) -> {
        if(oldText.length() < 3 && newText.length() >= 3) {
            tf2.requestFocus();
        }
    });

}
