The isSupported(TemporalField) method of ZoneOffset Class in java.time package is used to check if the temporalField, passed as the parameter, is supported by the ZoneOffset or not. This method returns a boolean value stating the same.
Syntax:
public boolean isSupported(TemporalField temporalField)
Parameters: This method accepts a parameter temporalField which is required to be checked if it is supported by this ZoneOffset instance.
Return Value: This method returns a boolean value stating whether this temporalField is supported by this ZoneOffset instance.
Below examples illustrate the ZoneOffset.isSupported() method:
Example 1:
// Java code to illustrate isSupported() 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 isSupported() method
System.out.println( "Is Second supported: "
+ zoneOffset.isSupported(ChronoField.OFFSET_SECONDS));
}
} |
ZoneOffset: +05:30 Is Second supported: true
Example 2:
// Java code to illustrate isSupported() method import java.time.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// Get the ZoneOffset instance
ZoneOffset zoneOffset
= ZoneOffset.ofHours( 5 );
System.out.println( "ZoneOffset: "
+ zoneOffset);
// Using isSupported() method
System.out.println( "Is Nano-Of-The-Day supported: "
+ zoneOffset.isSupported(ChronoField.NANO_OF_DAY));
}
} |
ZoneOffset: +05:00 Is Nano-Of-The-Day supported: false
