Loading images audio and other resources

suggest change

Java applets are able to load different resources. But since they are running in the web browser of the client you need to make sure that these resources are accessible. Applets are not able to access client resources as the local file system. If you want to load resources from the same URL the Applet is stored you can use the method getCodeBase() to retrieve the base URL. To load resources, applets offer the methods getImage() and getAudioClip() to load images or audio files.

Load and show an image 

public class MyImgApplet extends JApplet{

    private Image img;

    @Override
    public void init(){
        try {
            img = getImage(new URL("http://cdn.sstatic.net/stackexchange/img/logos/so/so-logo.png"));
        } catch (MalformedURLException e) { /* omitted for brevity */ }
    }
    @Override
        public void paint(Graphics g) {
            g.drawImage(img, 0, 0, this);
        } 
}

Load and play an audio file 

public class MyAudioApplet extends JApplet{

    private AudioClip audioClip;

    @Override
    public void init(){
        try {
            audioClip = getAudioClip(new URL("URL/TO/AN/AUDIO/FILE.WAV"));
        } catch (MalformedURLException e) { /* omitted for brevity */ }
    }
    @Override
    public void start() {
        audioClip.play();
    } 
    @Override
    public void stop(){
        audioClip.stop();
    }
}

Load and display a text file 

public class MyTextApplet extends JApplet{
    @Override
    public void init(){
        JTextArea textArea = new JTextArea();
        JScrollPane sp = new JScrollPane(textArea);
        add(sp);
        // load text
        try {
            URL url = new URL("http://www.textfiles.com/fun/quotes.txt");
            InputStream in = url.openStream();
            BufferedReader bf = new BufferedReader(new InputStreamReader(in));
            String line = "";
            while((line = bf.readLine()) != null) {
                textArea.append(line + "\n");
            }
        } catch(Exception e) { /* omitted for brevity */ }
    }
}
