Using this code, how do I achieve this in JavaFX? Please include screenshot of code compiling.

public class RegistrationFormApplication extends Application { @Override public void start(Stage primaryStage) throws Exception { primaryStage.setTitle("Registration Form JavaFX Application"); primaryStage.show(); } public static void main(String[] args) { launch(args); } }

private GridPane createRegistrationFormPane() { // Instantiate a new Grid Pane GridPane gridPane = new GridPane(); // Position the pane at the center of the screen, both vertically and horizontally gridPane.setAlignment(Pos.CENTER); // Set a padding of 20px on each side gridPane.setPadding(new Insets(40, 40, 40, 40)); // Set the horizontal gap between columns gridPane.setHgap(10); // Set the vertical gap between rows gridPane.setVgap(10); // Add Column Constraints // columnOneConstraints will be applied to all the nodes placed in column one. ColumnConstraints columnOneConstraints = new ColumnConstraints(100, 100, Double.MAX_VALUE); columnOneConstraints.setHalignment(HPos.RIGHT); // columnTwoConstraints will be applied to all the nodes placed in column two. ColumnConstraints columnTwoConstrains = new ColumnConstraints(200,200, Double.MAX_VALUE); columnTwoConstrains.setHgrow(Priority.ALWAYS); gridPane.getColumnConstraints().addAll(columnOneConstraints, columnTwoConstrains); return gridPane; }

4.3.2 Stimulus/Response Sequences The employee opens the application. The employee logs into the application. The employee selects Place Order from the Action menu. The system displays a list of customers in a drop down. The system displays a list of products in a drop down. The employee selects a customer and product. The employee enters the desired quantity of products to order. The employee presses the Place Order button to place the order. The system responds telling if the order was added successfully or if there was an error. 4.3.3 Functional Requirements REQ-1: Verify the employee has logged in. REQ-2: Check that there is enough quantity of the product to be ordered. If not, raise an exception, otherwise, continue. REQ-3: Insert a record in the order table to include in the customer ID, employee ID who is logged in, date of the order, and the order status (pending, delivered) REQ-4: Insert a record in the order_detail table to indicate the order ID, product ID, and quantity. REQ-5: Update the product table to deduct the number of items ordered. REQ-6: Display any errors either beside each input field or above all of the input fields. REQ-7: Validate that all of the input fields have been entered. The quantity must be a valid integer greater than zero. REQ-8: All of the database statements must execute in a database transaction. REQ-9: All input fields should be cleared if the transaction was successful.
