In this example, we will demonstrate how to get the current date time using LocalDateTime now() method.

Java LocalDateTime now() Method Example

LocalDateTime class provides below APIs to create the current date-time and specific date-time object respectively.

• static LocalDateTime now() - Obtains the current date-time from the system clock in the default time-zone.
• static LocalDateTime now(Clock clock) - Obtains the current date-time from the specified clock.
• static LocalDateTime now(ZoneId zone) - Obtains the current date-time from the system clock in the specified time-zone.

import java.time.Clock;
import java.time.LocalDateTime;
import java.time.Month;
import java.time.ZoneId;

public class LocalDateTimeExample {

    public static void main(String[] args) {
        createLocalDateTime();
    }
    private static void createLocalDateTime() {
     // Current date time
        LocalDateTime dateTime = LocalDateTime.now();
        System.out.println(dateTime);

        // Current date time from specified time-zone
        LocalDateTime dateTime2 = LocalDateTime.now(ZoneId.of("UTC"));
        System.out.println(dateTime2);

        // Current date time from specified clock
        LocalDateTime dateTime3 = LocalDateTime.now(Clock.systemUTC());
        System.out.println(dateTime3);
 
        // Specific date time
        LocalDateTime dateTime4 = LocalDateTime.of(2017, Month.JULY, 12, 10, 35, 55);
        System.out.println(dateTime4);
    }
}

Output:

2018-08-10T18:08:43.787
2018-08-10T12:38:43.789
2018-08-10T12:38:43.789
2017-07-12T10:35:55
