Duration minusMillis() method in Java
An immutable copy of a duration where some milliseconds are removed from it can be obtained using the minusMillis() method in the Duration class in Java. This method requires a single parameter i.e. the number of milliseconds to be subtracted and it returns the duration with the subtracted 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 100 milli seconds removed from the duration is: " + d.minusMillis(100));
}
}Output
The duration is: PT1S A copy with 100 milli seconds removed from the duration is: PT0.9S
Now let us understand the above program.
First, the duration is displayed. Then an immutable copy of the duration where 100 milliseconds are removed is obtained using the minusMillis() 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 milli seconds removed from the duration is: " + d.minusMillis(100));
