How to add number of days to current LocalDateTime in Java

In Java, we can add the number of days into current LocalDateTime value with the following steps:

  • Instantiate current LocalDateTime value using the LocalDateTime.now() static method.
  • Using the LocalDateTime.plusDays(long days) method to create new LocalDateTime value with number of days added.

AddDaysToCurrentLocalDateTimeExample.java 

import java.time.LocalDateTime;

public class AddDaysToCurrentLocalDateTimeExample {
    public static void main(String... args) {
        int numberOfDays = 20;

        // Add Number of Days to Current LocalDateTime
        LocalDateTime currentLocalDateTime = LocalDateTime.now();
        LocalDateTime newLocalDateTime = currentLocalDateTime.plusDays(numberOfDays);

        System.out.println("Number of days: " + numberOfDays);
        System.out.println("Current LocalDateTime: " + currentLocalDateTime);
        System.out.println("New LocalDateTime: " + newLocalDateTime);
    }
}
The output as below. 
Number of days: 20
Current LocalDateTime: 2022-09-06T22:26:58.601242800
New LocalDateTime: 2022-09-26T22:26:58.601242800
