In both cases this means that `item` could be an `int` or a `str`.

#### Possibly `None` { #possibly-none }

You can declare that a value could have a type, like `str`, but that it could also be `None`.

    for (AtomicInteger value : countMap.values()) {
      sum += value.get();
    }
    return Ints.saturatedCast(sum);
