Usage

From source file:SplashScreenDemo.java

public static void main(String[] args) {
    SplashScreen splashScreen = SplashScreen.getSplashScreen();
    Dimension size = splashScreen.getSize();
    int borderDim = (int) (size.height * 0.05);
    Graphics g = splashScreen.createGraphics();
    g.setColor(Color.blue);// w w w  .ja v a 2  s . co m
    for (int i = 0; i < borderDim; i++)
        g.drawRect(i, i, size.width - 1 - i * 2, size.height - 1 - i * 2);

    FontMetrics fm = g.getFontMetrics();
    int sWidth = fm.stringWidth("Initializing...");
    int sHeight = fm.getHeight();
    if (sWidth < size.width && 2 * sHeight < size.height) {
        g.setColor(Color.blue);
        g.drawString("Initializing...", (size.width - sWidth) / 2, size.height - 2 * sHeight);
    }

    splashScreen.update();

        Thread.sleep(5000);
