Error with handle(Event) in EventHandler - javafx

Question

I'm new new to javafx and I would like just to print the the coordinates of the mouse click.
I've seen examples but I've got an error in the EventHandler line that I don't understand, it says:
anonymous javafxapplication2.JavaFXApplication2$1 is not abstract and does not override abstract method handle(Event) in EventHandler
What's the problem? Thanks!
package javafxapplication2;
import javafx.application.Application;
import javafx.event.Event;
import javafx.event.EventHandler;
import javafx.event.EventType;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.input.MouseEvent;
import javafx.scene.shape.Line;
import javafx.stage.Stage;
public class JavaFXApplication2 extends Application {
#Override
public void start(Stage primaryStage) {
Line line = new Line();
Group root = new Group(line);
Scene scene = new Scene(root, 800, 800);
scene.addEventHandler(MouseEvent.MOUSE_CLICKED, new EventHandler() {
#Override
public void handle(MouseEvent event) {
System.out.println(event.getX());
System.out.println(event.getY());
}
}
primaryStage.setTitle("Disegna linee");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}

From looking at the documentation here on javafx handlers I believe your problem is that you need to provide the type to the new eventHandler like
scene.addEventHandler(MouseEvent.MOUSE_CLICKED,
new EventHandler<MouseEvent>() { // Was missing the <MouseEvent>
#Override
public void handle(MouseEvent event) { ... };
});
