LocalDateTime plus() method in Java
An immutable copy of a LocalDateTime where the required duration is added to it can be obtained using the plus() method in the LocalDateTime class in Java. This method requires two parameters i.e. the duration to be added and the TemporalUnit of the duration. Also, it returns the LocalDateTime object with the required duration added to it.
A program that demonstrates this is given as follows −
Example
import java.time.*;
import java.time.temporal.*;
public class Demo {
public static void main(String[] args) {
LocalDateTime ldt = LocalDateTime.now();
System.out.println("The LocalDateTime is: " + ldt);
System.out.println("The LocalDateTime after adding 3 days is: " + ldt.plus(3, ChronoUnit.DAYS));
}
}Output
The LocalDateTime is: 2019-02-18T07:00:06.404 The LocalDateTime after adding 3 days is: 2019-02-21T07:00:06.404
Now let us understand the above program.
First the LocalDateTime is displayed. Then an immutable copy of the LocalDateTime where 3 days are added to it is obtained using the plus() method and this is displayed. A code snippet that demonstrates this is as follows −
LocalDateTime ldt = LocalDateTime.now();
System.out.println("The LocalDateTime is: " + ldt);
System.out.println("The LocalDateTime after adding 3 days is: " + ldt.plus(3, ChronoUnit.DAYS));
