javafx fxml loader example

Here's an example of how to use the JavaFX FXML Loader in Assembly language:

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        FXMLLoader loader = new FXMLLoader(getClass().getResource("sample.fxml"));
        Parent root = loader.load();
        primaryStage.setTitle("JavaFX FXML Loader Example");
        primaryStage.setScene(new Scene(root, 600, 400));
        primaryStage.show();
    }

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

In this example, we create a JavaFX application by extending the Application class. In the start method, we create an instance of the FXMLLoader class and pass the path to the FXML file we want to load. We then call the load method to load the FXML file and retrieve the root element of the scene graph.

We set the title of the primary stage using the setTitle method and create a new Scene object with the root element and the desired width and height. Finally, we show the primary stage using the show method.

The main method is the entry point of the application. We simply call the launch method to start the JavaFX application.

Please note that Assembly language is not typically used for developing JavaFX applications. JavaFX is usually written in Java or a similar high-level language.
