Parsing

Parsing is the reverse process of formatting. We have a given string and try to parse it as a number. This can be accomplished via the NumberFormat.parse() method. By default, parsing doesn't take advantage of grouping (for example, without grouping, 5,50 K is parsed as 5; with grouping, 5,50 K is parsed as 550000).

If we condense this information into a set of helper methods, then we obtain the following output:

public static Number parseLocale(Locale locale, String number)     throws ParseException {  return parse(locale, Style.SHORT, false, number);}public static Number parseLocaleStyle(  Locale locale, Style style, String number) throws ParseException {  return parse(locale, style, false, number);}public static Number parseLocaleStyleRound( ...
