Case Insensitive DateFormatSymbols for parsing

[Bernd Eckenfels]

Hello Roger,

Thanks for the Tipp, that’s indeed a good reason why it’s not needed in the legacy SDF API.

Gruss
Bernd

Betreff: Re: Case Insensitive DateFormatSymbols for parsing

Hi Bernd,

Perhaps use java.time.format.DateTimeFormatter.

You can create a case-insensitive DateTimeFormatterBuilder using .parseCaseInsensitive().

https://docs.oracle.com/en/java/javase/18/docs/api/java.base/java/time/format/DateTimeFormatterBuilder.html#parseCaseInsensitive()

Regards, Roger

Hello,

I noticed that it is surprisingly hard to make SimpleDateFormat accept all-uppercase month names while parsing. Even with a custom DateFormatSymbols that’s hard because you can only specify a single symbol for a month name. For parsing it would be good if you can either specify a list of names like “June,june,JUNE” or have it allow a special case insensitive configuration option. (The list would also allow custom short forms like “ja” “fe” but not “ju”’

Am I missing something?

Gruss
