LocalDateTime now() Method in Java with Examples
In LocalDateTime class, there are three types of now() method depending upon the parameters passed to it.
now()
now() method of a LocalDateTime class used to obtain the current date-time from the system clock in the default time-zone.This method will return LocalDateTime based on system clock with default time-zone to obtain the current date-time.
Syntax:
public static LocalDateTime now()
Parameters: This method accepts no parameter.
Return value: This method returns the current date-time using the system clock.
Below programs illustrate the now() method:
Program 1:
import java.time.*;
public class GFG {
public static void main(String[] args)
{
LocalDateTime lt
= LocalDateTime.now();
System.out.println( "LocalDateTime : "
+ lt);
}
}
|
Output:
LocalDateTime : 2019-01-21T05:47:08.644
now(Clock clock)
now(Clock clock) method of a LocalDateTime class used to return the current date-time based on the specified clock passed as parameter
Syntax:
public static LocalDateTime now(Clock clock)
Parameters: This method accepts clock as parameter which is the clock to use.
Return value: This method returns the current date-time.
Below programs illustrate the now() method:
Program 1:
import java.time.*;
public class GFG {
public static void main(String[] args)
{
Clock cl = Clock.systemUTC();
LocalDateTime lt
= LocalDateTime.now(cl);
System.out.println( "LocalDateTime : "
+ lt);
}
}
|
Output:
LocalDateTime : 2019-01-21T05:47:20.949
now(ZoneId zone)
now(ZoneId zone) method of a LocalDateTime class used to return the current date-time from system clock in the specified time-zone passed as parameter.Specifying the time-zone avoids dependence on the default time-zone.
Syntax:
public static LocalDateTime now(ZoneId zone)
Parameters: This method accepts zone as parameter which is the zone to use.
Return value: This method returns the current date-time.
Below programs illustrate the now() method:
Program 1:
import java.time.*;
public class GFG {
public static void main(String[] args)
{
ZoneId zid = ZoneId.of( "Europe/Paris" );
LocalDateTime lt
= LocalDateTime.now(zid);
System.out.println( "LocalDateTime : "
+ lt);
}
}
|
Output:
LocalDateTime : 2019-01-21T06:47:22.756
