Dimension size = googleLabel.getPreferredSize();
r.width = size.width;
r.height = size.height;
googleLabel.setBounds(r);
// Append the Width of First Label to avoid overlapping
r.x += r.width + 5;
size = yahooLabel.getPreferredSize();
r.width = size.width;
r.height = size.height;
yahooLabel.setBounds(r);
xLoc -= 5;
if (xLoc < 0 )
xLoc = dimension.width;
}
}I repaired this as looping style.At that time.marquee text is not appear.Pls help me.Where I wrong?Thank in advance.Here is repaired program
