This article shows you how to add days to the current date, using the classic java.util.Calendar and the new Java 8 date and time APIs.
Few examples to convert classic Date to Java Time dates and vice versa: Convert java.util.Date to java.time.LocalDate, Convert java.util.Date to java.time.LocalDateTime, Convert java.util.Date to java.time.ZonedDateTime. The java.util.Date has no concept of time zone, and only represents the number of seconds passed since the Unix epoch time. The new Java 8 java.time.Instant is the equivalent class to the classic java.util.Date. The idea of the date conversion is to convert to an instant with a time zone.
Java 8 examples to show you how to convert from Instant to ZonedDateTime. Example to convert a Instant UTC+0 to a Japan ZonedDateTime UTC+9. Convert the Japan ZonedDateTime UTC+9 back to a Instant UTC+0/Z, the offset is taken care automatically.
Java 8 examples to show you how to convert from Instant to LocalDateTime and vice versa. The java.time.LocalDateTime has no concept of time zone, just provide a zero offset UTC+0.
