OffsetDateTime query() method in Java with Examples

query() method of an OffsetDateTime class used to query this OffsetDateTime using the specified query as parameter.The TemporalQuery object passed as parameter define the logic to be used to obtain the result from this OffsetDateTime.

Syntax:

public <R> R query(TemporalQuery<R> query)

Parameters: This method accepts only one parameter query which is the query to invoke.



Return value: This method returns the query result, null may be returned.

Exception:This method throws following Exceptions:

  • DateTimeException – if unable to query .
  • ArithmeticException – if numeric overflow occurs.

Below programs illustrate the query() method:

    {
  
        // create OffsetDateTime object
        OffsetDateTime olt
            = OffsetDateTime.parse(
                "2018-12-12T13:30:30+05:00");
  
        // apply query method of OffsetDateTime class
        String value
            = olt.query(
                     TemporalQueries.precision())
                  .toString();
  
        // print the result
        System.out.println("Precision value"
                           + " for OffsetDateTime is "
                           + value);
    }
}
