Should I use java.util.Date or switch to java.time.LocalDate

by

Despite the name, java.util.Date can be used to store both date and time (it stores UTC milliseconds offset since epoch)

I would definitely use the new API because of greater features:

  • Easier format/parsing. The API has its own format/parse methods
  • The API includes addition/subtraction operation (minusMinutes, plusDays, etc)

None of above are available on java.util.Date

Old Date can also be converted into LocalDateTime like this:

    Date oldDate = ...
    LocalDateTime newDateTime = 
      LocalDateTime.from(Instant.ofEpochMilli(oldDate.getTime()));
