JavaTime

To convert Java8's java.time.LocalDate to java.util.Date, do

Date date = Date.from(localDate.atStartOfDay().atZone(ZoneId.systemDefault()).toInstant());

To convert Java8's java.time.LocalDateTime to java.util.Date, do

Date date = Date.from(localDateTime.atZone(ZoneId.systemDefault()).toInstant());

You might be tempted to shorten it with LocalDateTime#toInstant(ZoneOffset), but there isn't a direct API to obtain the system default zone offset.

To convert Java8's java.time.ZonedDateTime to java.util.Date, do

Date date = Date.from(zonedDateTime.toInstant());
