How to calculate the difference between two date instances in Java

Question

I am using java.uti.Date class to find out the difference between two date instances. But, is there any simpler way to do this?

Answer 1

You can use Joda Time Library.

Interval i = new Interval(oldTime, new Instant());

Joda has two concepts:

1. Interval: It represents interval of time between two time instances i.e. 10 am and 12 am.
2. Duration: It represents the length of duration i.e. 2 hours.
