Duration plusMillis() method in Java
An immutable copy of a duration where some milliseconds are added to it can be obtained using the plusMillis() method in the Duration class in Java. This method requires a single parameter i.e. the number of milliseconds to be added and it returns the duration with the added milliseconds.
A program that demonstrates this is given as follows −
Example
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 1000 milliseconds added to the duration is: " + d.plusMillis(1000)); } }
Output
The duration is: PT1S A copy with 1000 milliseconds added to the duration is: PT2S
Now let us understand the above program.
First the duration is displayed. Then an immutable copy of the duration where 1000 milliseconds are added is obtained using the plusMillis() 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 1000 milliseconds added to the duration is: " + d.plusMillis(1000));
