Parse a datetime string that has no 'T' separator using java.time

I am trying to parse string "2023-05-10 09:41:00" to LocalTime using java.time library.

When I try LocalTime.parse("2023-05-10 09:41:00", DateTimeFormatter.ISO_LOCAL_DATE_TIME) I get java.time.format.DateTimeParseException. However when I try LocalTime.parse("2023-05-10T09:41:00", DateTimeFormatter.ISO_LOCAL_DATE_TIME) it works.

Is there any DateTimeFormatter constant I can use that works without the "T" separator? I am aware I can use a custom DateTimeFormatter but I would like to use a prepackaged constant from java or kotlin library like pseudo code DateTimeFormatter.ISO_LOCAL_DATE_TIME_WIHOUT_T.

Is there any DateTimeFormatter constant I can use that works without the "T" separator?

There is none because java.time is based on ISO 8601 which uses a date-time string with T as the time separator.

However, you can achieve it with some hacks (just for fun, not for production code).

Demo

public class Main {
    public static void main(String[] args) {
        String strDateTime = "2023-05-10 09:41:00";
        ParsePosition position = new ParsePosition(strDateTime.indexOf(' ') + 1);
        LocalTime time = LocalTime.from(DateTimeFormatter.ISO_LOCAL_TIME.parse(strDateTime, position));
        System.out.println(time);
    }
}

Output:

09:41

There is another hack which Ole V.V. has already mentioned in his comment.
