Getting All Available Time Zones in Java

The package java.time has APIs to get all the available zone ids. The API is getAvailableZoneIds().

import java.time.*;import java.util.*;public class AllTimeZones{   public static void main(String args[])   {      AllTimeZones allTimeZones = new AllTimeZones();      allTimeZones.proceed();   }   private void proceed()    {      List zoneList = new ArrayList(ZoneId.getAvailableZoneIds());      System.out.println("Available Time zones");      System.out.println("--------------------");              zoneList.forEach(zone - System.out.println(zone));       System.out.println("--------------------");                  System.out.println("Total zones: "+zoneList.size());            }}/*

Expected output:

[root@mypc]# java AllTimeZonesAvailable Time zones--------------------Asia/AdenAmerica/CuiabaEtc/GMT+9Etc/GMT+8...Europe/AthensUS/PacificEurope/Monaco--------------------Total zones: 595*/
