public class Main extends Application {

    public static void main(String[] args) {

    }

    @Override
    public void start(Stage primaryStage) {
        TextField[] textFields = new TextField[3];
        for (int i = 0; i < textFields.length; i++) {
            textFields[i] = new TextField();
        }

        VBox root = new VBox(textFields);
        Scene scene = new Scene(root, 200, 100);

        scene.setOnKeyPressed(event -> {
            for (TextField textField : textFields) {
                if (textField.isFocused()) {
                    System.out.println("聚焦的TextField的文本内容是：" + textField.getText());
                    break;
                }
            }
        });

        primaryStage.setScene(scene);
        primaryStage.show();
