question: public static String shorten ( String s , int length , String suffix ) { length -= suffix . length ( ) ; if ( s . length ( ) > length ) { for ( int j = length ; j >= 0 ; j -- ) { if ( CharUtil . isWhitespace ( s . charAt ( j ) ) ) { length = j ; break ; } } String temp = s . substring ( 0 , length ) ; s = temp . concat ( suffix ) ; } return s ; }
target:  Shorten string to given length.
