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)); }} |
Output:
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)); }} |
Output:
ZoneOffset: +05:00 Is Nano-Of-The-Day supported: false
