How to get difference between two dates?

(a) long diffInMilli = java.time.Duration.between(dateTime1, dateTime2).toMillis();

(b) long diffInMilli = java.time.difference(dateTime1, dateTime2).toMillis();

(c) Date diffInMilli = java.time.Duration.between(dateTime1, dateTime2).toMillis();

(d) Time diffInMilli = java.time.Duration.between(dateTime1, dateTime2).toMillis();

Answer 1

The correct option is (a) long diffInMilli = java.time.Duration.between(dateTime1, dateTime2).toMillis();

For explanation I would say: Java 8 provides a method called between which provides Duration between two times.
