在javafx或fxml中有什么方法可以验证TextField字符的长度吗？

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.control.TextFormatter;
import javafx.stage.Stage;

public class TextFieldLengthValidation extends Application {
    @Override
    public void start(Stage primaryStage) {
        TextField textField = new TextField();
        TextFormatter<String> textFormatter = new TextFormatter<>(change -> {
            String newText = change.getControlNewText();
            if (newText.length() <= 10) { // 设置最大长度为10
                return change;
            } else {
                return null;
            }
        });
        textField.setTextFormatter(textFormatter);

        Scene scene = new Scene(textField, 300, 250);
        primaryStage.setTitle("TextField Length Validation");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

        textField.textProperty().bindBidirectional(textProperty);

        textProperty.addListener((observable, oldValue, newValue) -> {
            if (newValue.length() > 10) { // 设置最大长度为10
