Should a retrieval method return 'null' or throw an exception when it can't produce the return value? [closed]

Answer 1

referring only to the case where null is not considered an exceptional behavior i am definitely for the try method, it is clear, no need to "read the book" or "look before you leap" as was said here

so basically:

bool TryFindObject(RequestParam request, out ResponseParam response)

and this means that the user's code will also be clear

...
if(TryFindObject(request, out response)
{
  handleSuccess(response)
}
else
{
  handleFailure()
}
...
