question: private String printDFormat ( final short x ) { return printDFormat ( Short . toString ( x ) ) ; }
target:  Format method for the d conversion specifer and short argument. For d format, the flag character '-', means that the output should be left justified within the field.  The default is to pad with blanks on the left.  A '+' character means that the conversion will always begin with a sign (+ or -).  The blank flag character means that a non-negative input will be preceded with a blank.  If both a '+' and a ' ' are specified, the blank flag is ignored.  The '0' flag character implies that padding to the field width will be done with zeros instead of blanks. The field width is treated as the minimum number of characters to be printed.  The default is to add no padding.  Padding is with blanks by default. The precision, if set, is the minimum number of digits to appear.  Padding is with leading 0s.
