Java Embedded Challenge for Raspberry Pi

This is the first time for me to be here JavaOne in SF. I jumped into the RaspberryPi challenge to do something without any skills about RaspberryPi.
Thanks to the this information(Introduction to JavaFX on Raspberry Pi) I finished a small application which shows the temperature.

• Screen 1

They already provided the raspberry Pi which measures the temperature.
What I did is download the jars from above slide(page 23) and implement the small amount codes.

code 1 shows how to get the temperature. That is it.

• code 1

    private String getTemperature() {
        Client client = ClientBuilder.newClient();
        String uriTemplate = "http://192.168.1.11:8080/things";
        return client.target(uriTemplate).path("/humidity").request().get(String.class);
    }

• code 2

    public void start(Stage primaryStage) {
        HBox root = new HBox();
        root.setPadding(new Insets(10));
        root.setSpacing(10);
        Label temperatureLable = new Label("温度：");
        final Text temperatureText = new Text();
        Button button = new Button("get temperature");
        button.setOnAction(new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent t) {
                temperatureText.setText(getTemperature());  // <-- when you click the button ,the temperature shows up
            }
        });
        primaryStage.setTitle("Hello Raspberry Pi!");
        root.getChildren().addAll(temperatureLable,temperatureText, button);
        primaryStage.setScene(new Scene(root, 500, 100));
        primaryStage.show();
    }

I am very impressed that they are so nice. They helped me a lot!!!
I had a wonderfull time joining this events!
Just keep coding....
