How to get the instance of the text field which has triggers the focus listener in JavaFX

I have a form consisting of three text fields. When the form is submitted, I validate each text field value to ensure it meets specific conditions. If a value is invalid, I change the border color of the respective text field to red. Now, I want to update the border color back to black if the user selects a text field and attempts to modify its value.

To streamline the process for all text fields, I aim to attach the same change listener to each one. However, the challenge lies in obtaining a reference to each text field so that I can specifically target it within the listener.

 keyWord.focusedProperty().addListener(textFieldFocusListener);
 date.focusedProperty().addListener(textFieldFocusListener);
 location.focusedProperty().addListener(textFieldFocusListener);

 ChangeListener<Boolean> textFieldFocusListener = (observable, oldValue, newValue) -> {

        // Change the border color of the text field to black if it is selected/focused

     };

>Solution :

Why not just write a method to create and register a listener for each text field?

private void addListenerToTextField(TextField textField) {
    textField.focusedProperty().addListener((observable, oldValue, newValue) -> {
        // do whatever you need with textField
    });
}

Which scales to multiple text fields in the same way

addListenerToTextField(keyWord);
addListenerToTextField(date);
addListenerToTextField(location);

or

Stream.of(keyWord, date, location).forEach(this::addListenerToTextField);
