ZoneOffset getAvailableZoneIds() method in Java with Examples
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:
import java.time.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
ZoneOffset zoneOffset
= ZoneOffset.of( "+05:30" );
Set<String> zoneIds
= zoneOffset.getAvailableZoneIds();
System.out.println( "First ZoneId in list:"
+ zoneIds.iterator().next());
}
}

Output:
First ZoneId in list:Asia/Aden
Example 2:
import java.time.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
ZoneOffset zoneOffset
= ZoneOffset.of( "Z" );
Set<String> zoneIds
= zoneOffset.getAvailableZoneIds();
System.out.println( "First ZoneId in list:"
+ zoneIds.iterator().next());
}
