Below programs illustrate the working of setTimeZone() Method of Calendar class:
Example 1:
// Java code to illustrate// setTime() method  import java.util.*;  public class Calendar_Demo {    public static void main(String[] args)    {          // Creating calendar object        Calendar calndr = Calendar.getInstance();          // Displaying the current time zone        String tz_name = calndr.getTimeZone()                             .getDisplayName();          System.out.println("The Current Time"                           + " Zone: " + tz_name);          TimeZone time_zone            = TimeZone.getTimeZone("GMT");          // Modifying the time zone        calndr.setTimeZone(time_zone);          // Displaying the modified zone        System.out.println("Modified Zone: "                           + calndr.getTimeZone()                                 .getDisplayName());    }} |
Output:
The Current Time Zone: Coordinated Universal Time Modified Zone: Greenwich Mean Time
Example 2:
// Java code to illustrate// setTimeZone() method  import java.util.*;  public class Calendar_Demo {    public static void main(String[] args)    {          // Creating calendar object        Calendar calndr = Calendar.getInstance();          // Displaying the current time zone        String tz_name = calndr.getTimeZone()                             .getDisplayName();          System.out.println("The Current Time"                           + " Zone: " + tz_name);          TimeZone time_zone            = TimeZone.getTimeZone("Pacific/Tahiti");          // Modifying the time zone        calndr.setTimeZone(time_zone);          // Displaying the modified zone        System.out.println("Modified Zone: "                           + calndr.getTimeZone()                                 .getDisplayName());    }} |
Output:
The Current Time Zone: Coordinated Universal Time Modified Zone: Tahiti Time
