Get TimeZone ID

String getID() Gets the ID of this time zone.

import java.util.TimeZone;
/*  ja  v  a 2 s . c om*/
public class Main {

  public static void main(String[] args) {
    TimeZone tz = TimeZone.getTimeZone("America/New_York");

    System.out.println(tz.getID());
  }
}

The output:

Get available timezone ids

The following two methods return available timezone ids.

static String[] getAvailableIDs()
Gets all the available IDs supported.
static String[] getAvailableIDs(int rawOffset)
Gets the available IDs according to the given time zone offset in milliseconds.

import java.util.TimeZone;
/*from  j  ava  2s . c  om*/
public class Main {

  public static void main(String[] args) {
   String[] ids = TimeZone.getAvailableIDs();
   for(String id: ids){
     System.out.println(id);
   }

  }
}

The output:

Get display name for a timezone

String getDisplayName() returns a time zone name in the default locale.

import java.util.TimeZone;
/*from j a  va 2  s .  c  om*/
public class Main {

  public static void main(String[] args) {
    TimeZone tz = TimeZone.getTimeZone("America/New_York");

    System.out.println(tz.getDisplayName());
  }
}
