Duration plusNanos() method in Java

Java 8ProgrammingObject Oriented Programming

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

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.time.Duration;
public class Demo {
   public static void main(String[] args) {
      Duration d = Duration.ofSeconds(1);
      System.out.println("The duration is: " + d);
      System.out.println("A copy with 100 nano seconds added to the duration is: " + d.plusNanos(100));
   }
}

Output

The duration is: PT1S
A copy with 100 nano seconds added to the duration is: PT1.0000001S

Now let us understand the above program.

First, the duration is displayed. Then an immutable copy of the duration where 10 nanoseconds are added is obtained using the plusNanos() method and this is displayed. A code snippet that demonstrates this is as follows −

Duration d = Duration.ofSeconds(1);
System.out.println("The duration is: " + d);
System.out.println("A copy with 100 nano seconds added to the duration is: " + d.plusNanos(100));
