I need to add a bunch of Labels and TextFields on button click.
In this case I need to add them as code right, not in the FXML?

I have Automobile class and I have to add like 10 labels and text fields when the user clicks a "Add Automobile" button.
Is there a better way than adding them like this:

Label label = new Label("State registration number:");

TextField textField1 = new TextField();

Label label2 = new Label("Brand:");

TextField textField2 = new TextField();

Label label3 = new Label("Model:");

TextField textField3 = new TextField();

Label label4 = new Label("Year of production:");

And so on... And if I need to add to them some other attributes, I need to write like 30+ more lines. Is there a better way of doing this? What is the best practice?

It's not the greatest solution but a good base to start with

import java.util.Arrays;

import java.util.List;

import java.util.Optional;



import javafx.application.Application;

import javafx.beans.value.ChangeListener;

import javafx.collections.FXCollections;

import javafx.collections.ObservableList;

import javafx.scene.Scene;

import javafx.scene.control.Label;

import javafx.scene.control.TextField;

import javafx.scene.layout.HBox;

import javafx.scene.layout.VBox;

import javafx.stage.Stage;



public class MultipleLabelTextFiledApp extends Application {

    private final ObservableList<CustomControl> customControls = FXCollections.observableArrayList();

    private final List<String> labels = Arrays.asList("label1", "label2", "label3", "label4", "label5");



    public static void main(String args) {

        launch(args);

    }



    @Override

    public void start(Stage stage) throws Exception {



        labels.stream().forEach(label -> customControls.add(new CustomControl(label)));



        VBox vBox = new VBox();

        vBox.getChildren().setAll(customControls);



        stage.setScene(new Scene(vBox));

        stage.show();



        getCustomControl("label1").ifPresent(customControl -> {

            customControl.getTextField().textProperty().addListener((ChangeListener<String>) (observable, oldValue, newValue) -> {

                System.out.println("textField with label1 handler new text=" + newValue);

            });

        });

    }



    private Optional<CustomControl> getCustomControl(String labelText) {

        return customControls.stream()

        .filter(customControl -> labelText.equals(customControl.getLabel().getText()))

        .findFirst();

    }

}



class CustomControl extends HBox {



    private final Label label = new Label();

    private final TextField textField = new TextField();



    {

        getChildren().addAll(label, textField);

    }



    public CustomControl(String text) {

        label.setText(text);

    }



    public Label getLabel() {

        return label;

    }



    public TextField getTextField() {

        return textField;

    }

}

First what you need is an int variable which its value is the amount of labels and textfields you want to create, it would be:

int amount = 10;

You should declare three arrays: One wich contains the text of the labels it would be:

String  text_labels = new String  {"State registration number:", "Brand:", "Model:", "..."};

Then you should declare the second array which may be:

Label  labels = new Label[amount];

And the third one:

TextField  textfields = new Text field[amount];

Once you haved declared them you have to initialize the labels and textfields. In order to do so you can do:

for(int i = 0; i < amount; i ++) {

  Label label = new Label(text_labels[i]);

  TextField textField = new TextField();

  labels[i] = label;

  textfields[i] = textField;

}

So labels[0] would be the same as the first label you wrote in your code and the same with the textfields.
