Warning Sound for Invalid Clicks

We want to make this program interactive so that if the user clicks anywhere other than the radio buttons or the slider, a warning sound is played. This will be the final part of this assignment.

Prepare the Sound File

Before writing any code, make sure you download the .wav file named warning.wav that can be found at the bottom of this page. Drag and drop it into the same file where your class is.

Placing this file in the same directory as your Java file (or inside your project’s resources folder if you're using one) will allow the system to play a warning whenever a disallowed area is clicked.

Also add the wave file to your /bin/application/ directory. Inside of this directory you should see a file called ChangingSquareApp.class. Make sure the wave file is next to it like this:

Load the Sound

We create a Media object from the sound file and pass it into a MediaPlayer. This lets us play the sound whenever we want. Add the following code right after creating the VBox root:

URL soundURL = getClass().getResource("warning.wav");
Media warningSound = new Media(soundURL.toString());
MediaPlayer mediaPlayer = new MediaPlayer(warningSound);

This loads the sound and prepares it for playback.
