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
