  • This seems to lose the fallback behavior that was inherent in the question. Commented Dec 22, 2022 at 17:42
  • @JimmyJames I agree. Without the context of what the sample code actually does, it's hard to know. I would posit that fallback isn't the only solution. Commented Dec 22, 2022 at 18:04
  • I thought it was pretty clear that the OP was trying to avoid duplication as a result of the need to call B in the both the case that A isn't applicable and if A failed. The call to C is only shown as a fallback. In general, you can't protect against exceptions in a pre-check. For example, an IO error must be handled at the time of the call.

  • That is very likely the case. I removed the assumption that it was necessary in this solution since yours already covered that. Commented Dec 22, 2022 at 19:37
