The from(TemporalAccessor) method of ZoneOffset Class in java.time package is used to obtain an instance of ZoneOffset using the offset in temporalAccessor passed as the parameter. This method takes the temporalAccessor as parameter in the form of TemporalAccessor and converts it into the ZoneOffset.
Syntax:
public static ZoneOffset from(TemporalAccessor temporalAccessor)
Parameters: This method accepts a parameter temporalAccessor which is TemporalAccessor to be converted into an ZoneOffset instance.
Return Value: This method returns a ZoneOffset instance parsed from the specified temporalAccessor.
Exception: This method throws DateTimeException if the temporalAccessor is invalid.
Below examples illustrate the ZoneOffset.from() method:
Example 1:
// Java code to illustrate from() method  import java.time.*;import java.time.temporal.*;  public class GFG {    public static void main(String[] args)    {          // Get the temporalAccessor        TemporalAccessor temporalAccessor            = ZonedDateTime.now();          // ZoneOffset using from() method        ZoneOffset zoneOffset            = ZoneOffset.from(temporalAccessor);          System.out.println(zoneOffset);    }} |
Z
Example 2: To demonstrate DateTimeException
// Java code to illustrate from() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          try {            // ZoneOffset using from() method            ZoneOffset zoneOffset                = ZoneOffset.from(LocalDate.now());        }          catch (Exception e) {            System.out.println(e);        }    }} |
java.time.DateTimeException: Unable to obtain ZoneOffset from TemporalAccessor: 2018-12-11 of type java.time.LocalDate
