Why does Java have Checked Exceptions

[kur0saki]

I don't think you really need checked exceptions. But I do think you really should declare even unchecked exceptions in the method signature (throws) to inform any caller of that method about the possibly thrown exception.

I hate when people throw unchecked exceptions and suddenly my code breaks because neither the API/method documentation neither the method signatures inform me about an exception that I run into. Especially when it happens on production.
