LocalDateTime plusWeeks() method in Java
An immutable copy of a LocalDateTime object where some weeks are added to it can be obtained using the plusWeeks() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the number of weeks to be added and it returns the LocalDateTime object with the added weeks.
A program that demonstrates this is given as follows −
Example
import java.time.*;
public class Demo {
public static void main(String[] args) {
LocalDateTime ldt = LocalDateTime.now();
System.out.println("The current LocalDateTime is: " + ldt);
System.out.println("The LocalDateTime with 4 weeks added is: " + ldt.plusWeeks(4));
}
}Output
The current LocalDateTime is: 2019-02-18T10:23:47.908 The LocalDateTime with 4 weeks added is: 2019-03-18T10:23:47.908
Now let us understand the above program.
First the current LocalDateTime is displayed. Then an immutable copy of the LocalDateTime where 4 weeks are added is obtained using the plusWeeks() method and this is displayed. A code snippet that demonstrates this is as follows −
LocalDateTime ldt = LocalDateTime.now();
System.out.println("The current LocalDateTime is: " + ldt);
System.out.println("The LocalDateTime with 4 weeks added is: " + ldt.plusWeeks(4));
