public class DownLoad {

	private boolean packFrame;
	public DownLoad()
	{
		packFrame = false;
        DLFrame dlframe = new DLFrame();
        if(packFrame)

        else
            dlframe.validate();
        Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();
        Dimension dimension1 = dlframe.getSize();
        if(dimension1.height > dimension.height)
            dimension1.height = dimension.height;

            dimension1.width = dimension.width;
        dlframe.setLocation((dimension.width - dimension1.width) / 2, (dimension.height - dimension1.height) / 2);
        dlframe.setVisible(true);
	}
	public static void main(String[] args) {
		 try
