The getTimeZone() method of TimeZone class in Java is used to know the actual TimeZone for any passed TimeZone ID.
Syntax:
public static TimeZone getTimeZone(String the_ID)
Parameters: The method takes one parameter the_ID of string datatype which refers to the ID of which the TimeZone is needed to be known.
Return Value: The method either returns the specified TimeZone for the passed ID or the GMT zone if the specified ID cannot be understood by the program.
Below programs illustrate the working of getTimeZone() Method of TimeZone:
Example 1:
// Java code to illustrate getTimeZone() method  import java.util.*;  public class TimeZoneDemo {    public static void main(String args[])    {          // Creating a TimeZone        TimeZone the_time_zone            = TimeZone.getDefault();          // Knowing the TimeZone        System.out.println("The TimeZone is: "                           + the_time_zone                                 .getTimeZone("GMT+5:30"));    }} |
Output:
The TimeZone is: sun.util.calendar.ZoneInfo[id="GMT+05:30", offset=19800000, dstSavings=0, useDaylight=false, transitions=0, lastRule=null]
Example 2:
// Java code to illustrate getTimeZone() method  import java.util.*;  public class TimeZoneDemo {    public static void main(String args[])    {          // Creating a TimeZone        TimeZone the_time_zone            = TimeZone.getDefault();          // Knowing the TimeZone        System.out.println("The TimeZone is: "                           + the_time_zone                                 .getTimeZone("GMT-3:30"));    }} |
Output:
The TimeZone is: sun.util.calendar.ZoneInfo[id="GMT-03:30", offset=-12600000, dstSavings=0, useDaylight=false, transitions=0, lastRule=null]
