In this article, we will learn how to use the instant() method in the Clock class in Java to obtain the current instant of a clock object. This method requires no parameters and returns an Instance representing the current timestamp of the clock. The Instant class is a part of the java.time package and represents a specific point on the timeline in UTC. Problem StatementGiven the Clock class in the java.time package, use the instant() method to obtain the current instant of a clock object. The instant() method requires no parameters and returns an Instant representing the current time in the ... Read More

The current instance of the clock in milliseconds can be obtained using the method millis() in the Clock Class in Java. This method requires no parameters and it returns the current instant of the clock in milliseconds. If the instance cannot be obtained for some reason, then the DateTimeException is thrown.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { Clock c = Clock.systemDefaultZone(); long ms = c.millis(); System.out.println("The clock is: " + c); ...

The equality of two Java clock objects can be checked using the method equals() in the Clock Class in Java. This method requires a single parameter i.e. the object that is to be compared with the existing clock object. Also it returns true if both the clock objects are equal and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.time.Clock; import java.time.ZoneId; public class Demo { public static void main(String[] args) { Clock c1 = Clock.systemDefaultZone(); Clock c2 = Clock.systemDefaultZone(); System.out.println("Clock c1: " + c1.toString()); ...

The current instance of the clock with the UTC time zone can be obtained using the method systemUTC() in the Clock Class in Java. This method requires no parameters and it returns the current instance of the clock with the UTC time zone.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { Clock c = Clock.systemUTC(); Instant i = c.instant(); ZonedDateTime zdt = i.atZone(c.getZone()); System.out.println(zdt.toString()); } }Output2019-02-07T08:00:46.924ZNow let us understand the ...

The current instance of the clock with the default time zone can be obtained using the method systemDefaultZone() in the Clock Class in Java. This method requires no parameters and it returns the current instance of the clock with the default time zone.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { Clock c = Clock.systemDefaultZone(); Instant i = c.instant(); ZonedDateTime zdt = i.atZone(c.getZone()); ...

The current ticking with the system clock in seconds can be obtained using the method tickSeconds() in the Clock Class in Java. This method requires a single parameter i.e. the time zone and it returns the current ticking value in seconds.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { ZoneId zone = ZoneId.of("Australia/Melbourne"); Clock c = Clock.tickSeconds(zone); System.out.println("The current ticking value in seconds is: " + ...

The instant of the base clock can be rounded off for the required duration using the method tick() in the Clock Class in Java. This method requires two parameters i.e. the base clock and the duration of the tick. Also, the instant of the base clock rounded off for the required duration is returned.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Main { public static void main(String[] args) { Clock bClock = Clock.systemDefaultZone(); Instant i = bClock.instant(); System.out.println("The Instant of the base clock is: ...

The current instance of the clock for the required zoneID can be obtained using the method system() in Clock Class in Java. This method requires a single parameter i.e. the zoneID or the time zone and it returns the current instance of the clock for that time zone.A program that demonstrates this is given as follows −Exampleimport java.time.*; public class Main { public static void main(String[] args) { ZoneId zone = ZoneId.of("Australia/Melbourne"); Clock c = Clock.system(zone); ZonedDateTime zdt = ...

A clock copy of the clock object can be obtained using the method withZone() in Clock Class in Java. This method is used on a clock object to obtain a clock copy. The withZone() method requires a single parameter i.e. the zone that is required to change the time zone. Also, it returns the clock copy of the clock object with the required time zone.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { Clock c1 = Clock.systemDefaultZone(); ZoneId zone = ...

The current ticking value in minutes can be obtained using the method tickMinutes() in the Clock Class in Java. This method requires a single parameter i.e. the time zone and it returns the current ticking value in minutes.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { ZoneId zId = ZoneId.of("Australia/Melbourne"); Clock c = Clock.tickMinutes(zId); System.out.println("The current ticking value in minutes is: " + c.instant()); ...
