Analyze the following code.

Question

```
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;

public class Test extends Application {
@Override // Override the start method in the Application class
public void start(Stage primaryStage) {
Button btOK = new Button("OK");

btOK.setOnAction(new EventHandler() {
public void handle(ActionEvent e) {
System.out.println("The OK button is clicked");
}
});

Scene scene = new Scene(btOK, 200, 250);
primaryStage.setTitle("MyJavaFX"); // Set the stage title
primaryStage.setScene(scene); // Place the scene in the stage
primaryStage.show(); // Display the stage
}

/**
* The main method is only needed for the IDE with limited JavaFX
* support. Not needed for running from the command line.
*/
public static void main(String[] args) {
launch(args);
}
}```
a. The program has a compile error because no handlers are registered with btOK.
b. The program has a runtime error because no handlers are registered with btOK.
