What 's wrong??

java fx application

package com.example;

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;

public class Home extends Application {

    public void start(Stage primaryStage) throws Exception{
        Group root = new Group();
        Button playButton = new Button();
        setOnAction(evt -> system.out.println("Playing"));

        primaryStage.setScene(new Scene(root, 300, 275));

    public static void main(String[] args) {

setOnAction is a method of the Button-Class or in this case of your playButton-Object created above. So would need to do:

``` playButton.setOnAction(evt -> System.out.println("Playing"));
