ZoneOffset getAvailableZoneIds() method in Java with Examples

Last Updated : 13 Dec, 2018

The getAvailableZoneIds() method of the ZoneOffset class of java.time package is used to get the set of available zone IDs. This set includes all available region-based IDs. The ID can be passed to of(String) to create a ZoneId. The set of zone IDs can increase over time, although in a typical application the set of IDs is fixed. Syntax:

public static Set getAvailableZoneIds()

Parameters: This method does not accepts any parameter. Return value: This method returns Set which are a modifiable copy of the set of zone IDs. Below examples illustrate the ZoneOffset.getAvailableZoneIds() method: Example 1:

Java

// Java code to illustrate getAvailableZoneIds() method

import java.time.*;
import java.util.*;

public class GFG {
    public static void main(String[] args)
    {

        // Get the ZoneOffset instance
        ZoneOffset zoneOffset
            = ZoneOffset.of("+05:30");

        // get available zones
        // using getAvailableZoneIds()
        Set<String> zoneIds
            = zoneOffset.getAvailableZoneIds();

        // print first record
        System.out.println("First ZoneId in list:"
                           + zoneIds.iterator().next());
    }
}

Output:

First ZoneId in list:Asia/Aden

Example 2:

Java

// Java code to illustrate getAvailableZoneIds() method

import java.time.*;
import java.util.*;

public class GFG {
    public static void main(String[] args)
    {

        // Get the ZoneOffset instance
        ZoneOffset zoneOffset
            = ZoneOffset.of("Z");

        // get available zones
        // using getAvailableZoneIds()
        Set<String> zoneIds
            = zoneOffset.getAvailableZoneIds();

        // print first record
        System.out.println("First ZoneId in list:"
                           + zoneIds.iterator().next());
    }
}

Output:

First ZoneId in list:Asia/Aden
