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
