MediaPlayer isn't working

Question

How do I use MediaPlayer to play m4a files? This is my code:

public void audioPlayerButtons(ActionEvent actionEvent) {
       String bip = "Songs/01 Clarity.m4a";
       Media hit = new Media(bip);
       MediaPlayer mediaPlayer = new MediaPlayer(hit);

       if (actionEvent.getSource() == playbtn) {
           mediaPlayer.play();

       } else if (actionEvent.getSource() == pausebtn) {
           mediaPlayer.pause();

       } else if (actionEvent.getSource() == forwardbtn) {
           mediaPlayer.stop();

       } else if (actionEvent.getSource() == backwardbtn) {
           mediaPlayer.isAutoPlay();
       }

but it's throwing an error:

Exception in thread "JavaFX Application Thread" java.lang.RuntimeException: java.lang.reflect.InvocationTargetException
    at javafx.fxml.FXMLLoader$MethodHandler.invoke(FXMLLoader.java:1762)
    at javafx.fxml.FXMLLoader$ControllerMethodEventHandler.handle(FXMLLoader.java:1645)
    at com.sun.javafx.event.CompositeEventHandler.dispatchBubblingEvent(CompositeEventHandler.java:86)

could you please help me understand why?

Basically, my aim is to make a mp3 player using mediaPlayer

According to the Javadocs for the Media constructor:

The source must represent a valid URI and is immutable. Only HTTP, FILE, and JAR URLs are supported. If the provided URL is invalid then an exception will be thrown.

The value you provided ("Songs/01 Clarity.m4a") is certainly not a valid URI, as it has whitespace.

You need something like

String bip = getClass().getResource("Songs/01 Clarity.m4a").toExternalForm();

(which will try to find the song relative to the current class, and is useful if you intend to bundle the m4a files with your application), or

String bip = new File("Songs/01 Clarity.m4a").toURI().toString();

which will look for the file on the file system, relative to the working directory.

In either case, you will likely need to change the path to get it correct.
