如何检查我的所有文本字段是否都为空JavaFX

ObservableList<Node> nodes = scene.getRoot().lookupAll(".text-field");

for (Node node : nodes) {
    if (node instanceof TextField) {
        TextField textField = (TextField) node;
        if (textField.getText().isEmpty()) {
            // 字段为空
        } else {
            // 字段不为空
        }
    }
}

import javafx.application.Application;
import javafx.collections.ObservableList;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class TextFieldCheck extends Application {

    @Override
    public void start(Stage primaryStage) {
        VBox root = new VBox();
        TextField textField1 = new TextField();
        TextField textField2 = new TextField();
        TextField textField3 = new TextField();
        root.getChildren().addAll(textField1, textField2, textField3);

        Scene scene = new Scene(root, 200, 200);
        primaryStage.setScene(scene);
        primaryStage.show();

        ObservableList<Node> nodes = scene.getRoot().lookupAll(".text-field");
        for (Node node : nodes) {
            if (node instanceof TextField) {
                TextField textField = (TextField) node;
                if (textField.getText().isEmpty()) {
                    System.out.println("字段为空");
                } else {
                    System.out.println("字段不为空");
                }
            }
        }
    }

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