TimeZoneDemo.java

import java.util.TimeZone;

public class TimeZoneDemo

{

    public static void main(String[] args)

    {

        /*

         * Parameters:

         * 

         * ID - the ID for a TimeZone, either an abbreviation such as

         * "PST", a full name such as "America/Los_Angeles", or a

         * custom ID such as "GMT-8:00". Note that the support of

         * abbreviations is for JDK 1.1.x compatibility only and full

         * names should be used.

         * 

         * Returns:the specified TimeZone, or the GMT zone if the

         * given ID cannot be understood.

         */

        TimeZone timeZone = TimeZone.getTimeZone("America/New_York");

        System.out.println(timeZone);

        System.out.println(timeZone.getDisplayName());

    }

}

Output
