Combining File Chooser and this MP3 class

Question

Hello all,
I was curious if anyone could help me figure out how to get a file to actually load once it is used with this code.
I'm unfamiliar with how it works and I was hoping for an explanation on it.
I wasn't sure if I had to have the program recgonize that I would like to load a mp3 or if it just would load it automatically...
Essentially, I want to be able to load a mp3 if I use the file chooser.
I can try to clarify my question more if anyone should need it.
Thank you

    // play the MP3 file to the sound card

        try {

            BufferedInputStream bis = new BufferedInputStream(fis);
            player = new Player(bis);

            System.out.println(e);

Thanks for the link
I've been looking over the sections and still confused with the code.
It's obvious that I have to do something with this portion of the code:
public void actionPerformed(ActionEvent e) {
    //Handle open button action.
    if (e.getSource() == openButton) {
        int returnVal = fc.showOpenDialog(FileChooserDemo.this);
        if (returnVal == JFileChooser.APPROVE_OPTION) {
            File file = fc.getSelectedFile();
            //This is where a real application would open the file.
            log.append("Opening: " + file.getName() + "." + newline);
        } else {
            log.append("Open command cancelled by user." + newline);
}I'm just not sure what.
