Java Clock class is part of Date Time API, java.time.Clock, of Java. The Java Date Time API was added from Java version 8.
getZone() method of Clock class returns the time-zone used to create dates and times of Clock class. Every Clock class needs a Time Zone for obtaining the current instant of time and convert that instance to a date or time. So this method returns the time-zone used for this process.
Syntax:
public abstract ZoneId getZone()
Returns Value: This Method returns the time-zone used to create Clock class.
Example:
Input:: a clock class Object e.g Clock.systemUTC() Output:: TimeZone e.g. Z Explanation:: when Clock.getZone() is called, then it returns a Time Zone used in Class Object
Below programs illustrates getZone() method of java.time.Clock class:
Program 1: Get the TimeZone of the Clock object, created with systemDefaultZone, using getZone()
Java
// Java program to demonstrate getZone()// method of Clock classimport java.time.*;// create classpublic class getZoneMethodDemo { // Main method public static void main(String[] args) { // create Clock Object Clock clock = Clock.systemDefaultZone(); // get TimeZone of Clock object // using getZone() method ZoneId zoneid = clock.getZone(); // print details of TimeZone System.out.println("ZoneId for class " + clock + " is " + zoneid); }} |
ZoneId for class SystemClock[Etc/UTC] is Etc/UTC
Program 2:Get TimeZone of Clock object, with Zone “Asia/calcutta”, using getZone().
Java
// Java program to demonstrate getZone()// method of Clock classimport java.time.*;// create classpublic class getZoneMethodDemo { // Main method public static void main(String[] args) { // create a Zone Id for Calcutta ZoneId zoneId = ZoneId.of("Asia/Calcutta"); // create Clock Object by passing zoneID Clock clock = Clock.system(zoneId); // get TimeZone of Clock object // using getZone() method // and save ZoneId as zoneid variable ZoneId zoneid = clock.getZone(); // print details of TimeZone System.out.println("ZoneId for clock is " + zoneid); }} |
ZoneId for clock is Asia/Calcutta
