That's a big ongoing discussion. You can read an old blog post from Brian Goetz which is mostly a fan (at least in 2007) of checked exception but pointing out that is was causing some ugly code. It has highly improved in JDK 7 and 8.
http://briangoetz.blogspot.ca/2007/06/remove-checked-exceptions.html Then you have Josh Bloch, who's talking about it in Effective Java Use checked exceptions for recoverable conditions and runtime exceptions for programming errors So, he's ok with them, but in a limited scope. I tend to agree with him. I remember those terrible times when Hibernate was throwing checked HibernateExceptions. That was a really bad decision because when there's an exception in Hibernate, the only thing you want to do is to rollback the transaction. Which normally occurs at a really high level. It's the same with IOExceptions. In general, there's not much you can do about them. Finally, a really nice article from Brian commenting Josh, Rod Johnson and Bruce Eckel. They have a decent reputation ;-) http://www.ibm.com/developerworks/library/j-jtp05254/ On 12 August 2016 at 18:00, Kevin Burton <burtona...@gmail.com> wrote: > Both the Elasticsearch and Cassandra drivers now use unchecked exceptions. > > Personally I consider this harmful. > > It's entirely possible I'm wrong here, but I can't find any sort of > definitive/referential explanation why some consider checked exceptions to > be harmful / evil. > > I've found a few documents but most of these are from junior (IMO) > programmers complaining that they don't know what to do with.
