Try Catch blocks inside or outside of functions and error handing

Question

This is more a general purpose programming question than language specific. I\'ve seen several appraoches to try and catches.

One is you do whatever preprocessing on

Answer 1

I generally consider if as the caller of the method I can use an exception in any way (like, to recover from it by taking a different approach) or if it makes no difference and just went wrong if the exception occurs. So in the former case I'll declare the method to throw the exception while in the latter I'll catch it inside of the method and don't bother the caller with it.
