An even better way to handle this is to return an Option<T>. Guava has
something along these lines [1]. Unfortunately Guava's version of Option
is not a monad which makes it not as useful as it could be.

It looks cool first, but I'm totally unconvinced that replacing null
checks by "isPresent()" checks really makes things better.
That's the particular problem with the Guava implementation which
doesn't provide map/flatMap methods. Having these you don't need
isPresent() but rather lift your operation into the monad.
