Have you ever tried fading out a JLabel or a component from transparency to semi transparency and then to pure opacity. This is very simple using the Timer class. The image on the side, is just a mere sample output, but the program's output is much more beautiful. In this I have applied fade effect for both foreground and background. Saying more is useless, see it in action instead.

// Set a white background for the JFrame

// Create an ImageIcon
icon=new ImageIcon("D:\\Documents and Settings\\Gutha\\My Documents\\Downloads\\cloud_icon.png");
// Create a JLabel
l=new JLabel("Java-Demos.blogspot.com");
// Set the text position bottom center relative
// to the icon so that the icon appears as a
// a desktop icon
l.setVerticalTextPosition(SwingConstants.BOTTOM);
l.setHorizontalTextPosition(SwingConstants.CENTER);
// Set the icon to the JLabel
l.setIcon(icon);
// Set foreground
l.setForeground(new Color(0,0,0,0));
l.setOpaque(true);
// Set some font
l.setFont(new Font("Myriad Pro",Font.PLAIN,28));
// Add the JLabel
add(l);
// Create a Timer with that executes
// each 1ms
t=new Timer(10,new ActionListener(){
public void actionPerformed(ActionEvent ae)
{
// Increase the alpha value by time
// so that transparency decreases for each
// actionPerformed() call
l.setForeground(new Color(0,0,0,x++));
l.setBackground(new Color(255,255,255,x));
if(x==255) t.stop();
}
});
// Set some initial delay, optional
t.setInitialDelay(200);
// Start the timer
t.start();
// Set size and show the frame
setSize(500,500);
setVisible(true);
setLocationRelativeTo(null);
