How can you create a JavaFX application that extends the Application class?Question 2Answera.By implementing the Application interface.b.By creating a class that extends the Application class and overriding the start() method.c.By calling the Application.create() method and passing a class that implements the Application interface.d.By creating an instance of the Application class and calling the start() method.

To create a JavaFX application that extends the Application class, you should follow these steps:

1. Create a class that extends the Application class:

   • This is necessary because Application is an abstract class that provides the basic structure for a JavaFX application.

2. Override the start(Stage primaryStage) method:

   • The start method is an abstract method in the Application class that you must implement. This method is the entry point for your JavaFX application and is called when the application is launched.

3. Launch the application using the launch method:

   • The launch method is a static method in the Application class that starts the JavaFX application. You typically call this method from the main method of your class.

Here is a simple example to illustrate these steps:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.stage.Stage;

public class MyJavaFXApp extends Application {

    @Override
    public void start(Stage primaryStage) {
        // Create a simple label
        Label label = new Label("Hello, JavaFX!");

        // Create a scene with the label
        Scene scene = new Scene(label, 400, 200);

        // Set the scene on the primary stage
        primaryStage.setScene(scene);

        // Set the title of the stage
        primaryStage.setTitle("My JavaFX Application");

        // Show the stage
        primaryStage.show();
    }

    public static void main(String[] args) {
        // Launch the JavaFX application
        launch(args);
    }
}

Explanation of the Answer Choices:

a. By implementing the Application interface:

• Incorrect. Application is a class, not an interface. You need to extend it, not implement it.

b. By creating a class that extends the Application class and overriding the start() method:

• Correct. This is the correct way to create a JavaFX application.

c. By calling the Application.create() method and passing a class that implements the Application interface:

• Incorrect. There is no create method in the Application class, and Application is not an interface.

d. By creating an instance of the Application class and calling the start() method:

• Incorrect. You cannot directly instantiate the Application class because it is abstract. You need to extend it and override the start method.

So, the correct answer is:

b. By creating a class that extends the Application class and overriding the start() method.
