How to use LocalDateTime in Java?

Explanation

1. LocalDateTime is a date-time target. You can also think of it as a combination of LocalDate and LocalTime. In operation, it is roughly the same.

Examples

Instant instant = sylvester
        .atZone(ZoneId.systemDefault())
        .toInstant();
 
Date legacyDate = Date.from(instant);
System.out.println(legacyDate);     // Wed Dec 31 23:59:59 CET 2014
