question: private String processIntegerToken ( String token ) { String result = token . replaceAll ( "" + groupSeparator , "" ) ; boolean isNegative = false ; int preLen = negativePrefix . length ( ) ; if ( ( preLen > 0 ) && result . startsWith ( negativePrefix ) ) { isNegative = true ; result = result . substring ( preLen ) ; } int sufLen = negativeSuffix . length ( ) ; if ( ( sufLen > 0 ) && result . endsWith ( negativeSuffix ) ) { isNegative = true ; result = result . substring ( result . length ( ) - sufLen , result . length ( ) ) ; } if ( isNegative ) result = "-" + result ; return result ; }
target:  The integer token must be stripped of prefixes, group separators, and suffixes, non ascii digits must be converted into ascii digits before parse will accept it.
