getCalendarTypeForString

public static int getCalendarTypeForString(java.lang.String oneChar)

slashParse

public static java.util.Calendar slashParse(java.lang.String str,
                                            java.lang.String dateFormat,

                                            java.lang.Exception

This method assumes the dateFormat has a separator char in it, and that we can use that to determine what the user entered by using that separator to split up the user entered date, and then do some logic on it. This is by no means a foolproof method and should not be relied upon returning 100% correct dates all the time.

Parameters:

str - String to parse

dateFormat - DateFormat to use

separators - Separator chars that can be encountered

locale - Locale

Returns:

Calendar

Throws:

CalendarDateParseException - If date could not be parsed

java.lang.Exception - If any step of the parsing failed
