/**

* This method creates small status bars in ASCII art for printing in the

* console or in log files. The status bar looks like "[********.........]"

* without shown percentage or "[*******........] ( 45%)" with percentage

* shown.

* @param length

*            is the total length of the status bar. In this length the

*            brackets are included. The percentage number is extra length.

* @param d

*            is the percentage to show.

* @param showPercentage

*            defines whether the percentage value is to be shown.

* @return A String is returned containing the ASCII art representation of

*         the string

public static String createPercentageBar(int length, double d,/**来自 时   代    Java - nowjava.com**/

} else {

buffer.append('.');

}

buffer.append(']');

if (showPercentage) {
