ZonedDateTime zdt = gc.toZonedDateTime() OffsetTime ot = gc.toZonedDateTime().toOffsetDateTime().toOffsetTime()
OffsetDateTime od = gc.toZonedDateTime().toOffsetDateTime() LocalDateTime ldt = gc.toZonedDateTime().toLocalDateTime() LocalTime lt = gc.toZonedDateTime().toLocalTime() LocalDate ld = gc.toZonedDateTime().toLocalDate() The date is defined in the same manner as was used for the previous parsing example, but this pattern also includes the hour, minutes, and a Java SimpleDateFormat: Easily get the date, time, or datetime Example 4- set date to be a future date getDate ( String parameterName, Calendar cal) For example, 01/05/12 could mean January 5, 2012, or May. GregorianCalendar gc = new GregorianCalendar(2014, 1, 11, 15, 45, 50)
#Java.util.sql setdate how to#
The following code shows how to convert GregorianCalendar to ZonedDateTime and vice versa. Sets the designated parameter to the given date and calendar values. We can convert Instant to ZonedDateTime and then convert ZonedDateTime to GregorianCalendar with the from() method from GregorianCalendar. LocalDate localDate sqlDate. sqlDate ( todayLocalDate ) And going the other direction. We can convert GregorianCalendar to ZonedDateTime which can be converted to any other class in the new Date-Time API. Convert to To convert, use new methods added to the old date-time classes. The above code produces the following results. The following code shows how to convert date to instant. .FileTime from() Converted to Instant..FileTime toInstant() Convert to Instant.valueOf() Converts from LocalDateTime.TimeZone.toZoneId() converts a TimeZone object to a ZoneId.om(ZonedDateTime) Creates a GregorianCalendar object using the default locale in the ZonedDateTime instance.If you are using Java 8, then better to use new Date/Time API in java.time. able to keeps both date and time, and used in general scenario, but considered as obsolete after Java 8. GregorianCalendar.toZonedDateTime() Converts a GregorianCalendar instance to a ZonedDateTime. used in JDBC to store (and use to retrieve) a date only value.The from() method creates a Date object from an Instant.toInstant() Converts a Date object to an Instant.Calendar.toInstant() converts a Calendar object to an Instant.When dealing with JDBC we can use with caution. We need to remember about special cases: leap seconds, different timezones etc. stores a date only value and is commonly used in JDBC. The JDK 8 datetime API defines several methods to convert between java.util and java.time objects. Class stores a date-time value as milliseconds since the epoch. The old datetime API is defined in the java.util package, while the new Java 8 datetime API is defined in the java.time package. Before Java 8, Java dates and times were defined by the, and classes and their subclasses such as.
