In Handling Exceptions from the Sun Java Tutorial, stresses the use of checked exceptions:
If a client can reasonably be expected to recover from an exception, make it a
checked exception. If a client cannot do anything to recover from the exception,
make it an unchecked exception
Code written using checked exceptions tends to exhibit a couple of problems: catch clauses are often stubbed out for expediency, leading to "swallowed" exceptions. Also, all calling code ends up bloating with handling for errors that the caller may not want/need to handle.
Why not let callers catch what they want, otherwise let the error propogate up the chain? Rod defines the following rule of thumb from when to use a checked exception:
Should all callers handle this problem? Is the exception essentially a second return value for the method?
I seems to me right now that this is the way to go. Basically, throw checked if the caller can and should do something about it, otherwise throw unchecked.
