Java SplashScreen transparent image

Question

I have an application that takes 6 seconds to start, and I want to add a splash screen. I have this code:

public class SplashScreen extends JWindow {
    private static final long serialVersionUID = 1L;

    Image bi;
    ImageIcon ii;

    boolean loaded = false;

    public SplashScreen(String path) {
        try {
            bi = Toolkit.getDefaultToolkit().getImage(path);
            ii = new ImageIcon(bi);
            setSize(ii.getIconWidth(), ii.getIconHeight());
            setLocationRelativeTo(null);
            loaded = true;
        } catch (Exception exception) {
            exception.printStackTrace();
        }
    }

    public void showSplashScreen(boolean flag) {
        if (!loaded) {
            System.err.println("Splash screen image isn't loaded.");
            return;
        }
        setVisible(flag);
    }

    public void dispose() {
        dispose();
    }

    public void paint(Graphics g) {
        g.drawImage(bi, 0, 0, null);
    }
}

The picture looks fine, but I want it to look transparent, and I can not get it.

you can set The opacity of your JWindow that will make it transparent

setUndecorated(true); setOpacity(0.5f);

I am using JFrame and it will remove the titlebar too,

it worked for me
