LocalDateTime plusDays() method in Java

Java 8Object Oriented ProgrammingProgramming

An immutable copy of a LocalDateTime object where some days are added to it can be obtained using the plusDays() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the number of days to be added and it returns the LocalDateTime object with the added days.

A program that demonstrates this is given as follows −

Example

 Live Demo

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 10 days added is: " + ldt.plusDays(10));
   }
}

Output

The current LocalDateTime is: 2019-02-16T11:33:17.040
The LocalDateTime with 10 days added is: 2019-02-26T11:33:17.040

Now let us understand the above program.

First the current LocalDateTime is displayed. Then an immutable copy of the LocalDateTime where 10 days are added is obtained using the plusDays() 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 10 days added is: " + ldt.plusDays(10));
