What should be the best Exception Handling Strategy

Question

UI--> Method1 -->Method2

Answer 1

If you can't recover from the exception in the method where the exception happens, don't try to catch it (unless you want to log it, in which case throw it again after logging). Then catch at the UI-level.

Trying to catch exceptions at every level just adds bloat to your code.
