The from() method of ZonedDateTime class in Java is used to get instance of ZonedDateTime from TemporalAccessor object passed as parameter. A TemporalAccessor represents an arbitrary set of date and time information and this method helps to get an instant of ZonedDateTime based on the specified TemporalAccessor object.
Syntax:
public static ZonedDateTime
from(TemporalAccessor temporal)
Parameters: This method accepts a single parameter temporal which represents the temporal object to convert. This is a mandatory parameter and it should not be NULL.
Return value: This method returns a zoned date-time.
Exception: This method throws a DateTimeException if unable to convert to an ZonedDateTime.
Below programs illustrate the from() method:
Program 1:
Java
// Java program to demonstrate// ZonedDateTime.from() methodimport java.time.*;public class GFG { public static void main(String[] args) { // create a ZonedDateTime object ZonedDateTime zonedDT = ZonedDateTime.now(); // create a ZonedDateTime object using // from() method ZonedDateTime result = ZonedDateTime.from(zonedDT); // print result System.out.println("ZonedDateTime: " + result); }} |
Output:
ZonedDateTime: 2018-12-12T19:03:06.445Z[Etc/UTC]
Program 2:
Java
// Java program to demonstrate// ZonedDateTime.from() methodimport java.time.*;public class GFG { public static void main(String[] args) { // create a OffsetDateTime object OffsetDateTime offset = OffsetDateTime.now(); // create a ZonedDateTime object using // from() method ZonedDateTime result = ZonedDateTime.from(offset); // print result System.out.println("ZonedDateTime: " + result); }} |
Output:
ZonedDateTime: 2018-12-12T19:03:09.523Z
