All-Encompassing Try

Answer:
You should catch exceptions where you intend to handle them. It makes no sense to catch exceptions only at the end of a program when many exceptions are recoverable. For example, network servers need to be able to recover from network I/O errors. You can only do this if you catch exceptions at the point of an anticipated failure point. But you must ensure that you take proper fault-recovery steps. Only fatal and non-recoverable exceptions resulting in the termination of the program should be caught at the end of the program.
