ZoneOffset query(TemporalQuery) method in Java with Examples

The query(TemporalQuery) method of ZoneOffset Class in java.time package is used to execute a query this ZoneOffset using the TemporalQuery passed as the parameter. This method returns the query result in the form of specified type.

Syntax:

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

Parameters: This method accepts a parameter TemporalQuery which is the query to be executed upon on this ZoneOffset.



Return Value: This method returns a R type query result of the specified query.

Exceptions: This method throws:

  • DateTimeException: if unable to query (defined by the query).
  • ArithmeticException: if numeric overflow occurs (defined by the query).

Below examples illustrate the ZoneOffset.query() method:

// Java code to illustrate query() method
  
import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // Get the ZoneOffset instance
        ZoneOffset zoneOffset
            = ZoneOffset.of("+05:30");
        System.out.println("ZoneOffset: "
                           + zoneOffset);
  
        // Using query() method
        System.out.println("Offset value: "
                           + zoneOffset.query(TemporalQueries.offset()));
    }
}
