Clock Class tick() method

• tick() method is available in java.time package.
• tick() method is used to get a Clock that returns the current instant tick the given base clock (base_cl) discarded to the close occurrence of the given duration (time_du).
• tick() method is a static method, it is accessible with the class name and if we try to access the method with the class object then we will not get an error.
• tick() method does not throw an exception at the time of representing Clock.

Syntax:

    public static Clock tick(Clock base_cl, Duration time_du);

Parameter(s):

• Clock base_cl – represents the base clock in which to add to the given duration.
• Duration time_du – represents the duration in which to add the given clock.

Return value:

The return type of this method is Clock, it returns Clock that ticks in entire units of the given duration.

Example:

// Java program to demonstrate the example 
// of tick(Clock base_cl, Duration time_du) method of Clock

import java.time.*;

public class TickOfClock {
    public static void main(String args[]) {
        // Instantiates two ZoneId for Accra and Asmara
        ZoneId zone_1 = ZoneId.of("Africa/Accra");
        ZoneId zone_2 = ZoneId.of("Africa/Asmara");

        // Initialize two Clock objects 
        // and one Duration
        Clock cl1 = Clock.system(zone_1);
        Clock cl2 = Clock.system(zone_2);
        Duration offset = Duration.ofNanos(20000);

        // generates a new Clock from the
        // given clock(cl1) with the given duration 
        // truncated 
        Clock cl_tick = cl1.tick(cl1, offset);

        // Display cl1 and cl_tick instant
        System.out.println("cl1.instant(): " + cl1.instant());
        System.out.println("cl_tick.instant(): " + cl_tick.instant());

        System.out.println();

        // generates a new Clock from the
        // given clock(cl2) with the given duration 
        // truncated
        cl_tick = cl2.tick(cl2, offset);

        // Display cl2 and cl_tick instant
        System.out.println("cl2.instant(): " + cl2.instant());
        System.out.println("cl_tick.instant(): " + cl_tick.instant());
    }
}

Output

cl1.instant(): 2020-05-13T21:43:13.551129Z
cl_tick.instant(): 2020-05-13T21:43:13.598720Z

cl2.instant(): 2020-05-13T21:43:13.599785Z
cl_tick.instant(): 2020-05-13T21:43:13.600620Z
