      O método get espera até que o future tem um resultado válido e (dependendo do modelo é usado) recupera. Ele efetivamente chama wait(), a fim de aguardar o resultado.
      Original:
      The get method waits until the future has a valid result and (depending on which template is used) retrieves it. It effectively calls wait() in order to wait for the result.
