Getting All Available IDs of TimeZones Example

The following example shows the usage of Java TimeZone getAvailableIDs() method to get the available time zoen ids. We've retrieved the available timezone ids using getAvailableIDs in form of String[] and then iterated them to print.

package com.tutorialspoint;

import java.util.TimeZone;

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

      // getting available Ids 
      String[] availId = TimeZone.getAvailableIDs();      
      
      // checking available Ids
      System.out.println("Available Ids are: ");

      for (int i = 0; i<availId.length; i++) {
         System.out.println(availId[i]);
      } 
   }    
}

Output

Let us compile and run the above program, this will produce the following result.

Available Ids are: 
Africa/Abidjan
Africa/Accra
Africa/Addis_Ababa
Africa/Algiers
