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:
Example 1:
// 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()));    }} |
Output:
ZoneOffset: +05:30 Offset value: +05:30
Example 2:
// 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("Z");        System.out.println("ZoneOffset: "                           + zoneOffset);          // Using query() method        System.out.println("Zone value: "                           + zoneOffset.query(TemporalQueries.zone()));    }} |
Output:
ZoneOffset: Z Zone value: Z
