Convert LocalDateTime to Date and back

At the moment i have to write a lot of Integeration Tests for a migration project. The old code uses java.util.Date a lot, but the project runs in Java 17. So i wanted to use the newer Date Classes for my tests.

I used the following two helper methods to convert Date to LocalDateTime and back.

private LocalDateTime toLocalDateTime(Date toConvert) { var instant = toConvert.toInstant(); var zonedDateTime = instant.atZone(ZoneId.systemDefault()); return zonedDateTime.toLocalDateTime(); } private Date toDate(LocalDateTime toConvert) { var zonedDateTime = toConvert.atZone(ZoneId.systemDefault()); return Date.from(zonedDateTime.toInstant()); }
