In Instant class, there are two types of now() method depending upon the parameters passed to it.
now()
now() method of a Instant class used to obtain the current instant from the system UTC clock.This method will return instant based on system UTC clock.
Syntax:
public static Instant now()
Parameters: This method accepts no parameter.
Return value: This method returns the current instant using the system clock
Below programs illustrate the now() method:
Program 1:
// Java program to demonstrate// Instant.now() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create an Instant object        Instant lt            = Instant.now();          // print result        System.out.println("Instant : "                           + lt);    }} |
Instant : 2019-01-21T05:47:26.853Z
now(Clock clock)
now(Clock clock) method of a Instant class used to return the current instant based on the specified clock passed as parameter.
Syntax:
public static Instant now(Clock clock)
Parameters: This method accepts clock as parameter which is the clock to use.
Return value: This method returns the current instant.
Below programs illustrate the now() method:
Program 1:
// Java program to demonstrate// Instant.now() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a clock        Clock cl = Clock.systemUTC();          // create an Instant object using now(Clock)        Instant lt            = Instant.now(cl);          // print result        System.out.println("Instant : "                           + lt);    }} |
Instant : 2019-01-21T05:47:29.886Z
