Since there's no way to meaningfully subtract 1 day from 1 month, there are cases where the operation fails in IllegalStateException. Formally the computation is defined as follows. First, we can assume that two Durations are both positive without losing generality. (i.e., (-X)-Y=-(X...

The-operator will replace the two values with the difference between the two values, just like with the+operator. You can create longer chains of subtractions and thus subtract more values from each other. Here is an example of subtracting two values from another in a single Java statement: ...
