UnsupportedOperationException – Why can’t you call toInstant() on a java.sql.Date?

February 13, 2023 by Tarik

The correct mapping between java.sql.Date and java.time is LocalDate:

LocalDate date = sqlDate.toLocalDate();

If you really must, you can then derive an Instant, although the extra information (time) will be arbitrary. For example:

Instant i = date.atStartOfDay(ZoneOffset.UTC).toInstant();
