Java subtract LocalTime

Question

I have two LocalTime objects:

LocalTime l1 = LocalTime.parse("02:53:40"); LocalTime l2 = LocalTime.parse("02:54:27"); 

How can I found different in minutes between them?

Answer 1

Use until or between, as described by the api

import java.time.LocalTime; import static java.time.temporal.ChronoUnit.MINUTES;  public class SO {     public static void main(String[] args) {         LocalTime l1 = LocalTime.parse("02:53:40");         LocalTime l2 = LocalTime.parse("02:54:27");         System.out.println(l1.until(l2, MINUTES));         System.out.println(MINUTES.between(l1, l2));     } }

Answer 2

Since Java 8 you can use Duration class. I think that gives the most elegant solution:

long elapsedMinutes = Duration.between(l1, l2).toMinutes();
