ZoneOffset isSupported(TemporalField) method in Java with Examples

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

// 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

// 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
