Why should I not wrap every block in “try”-“catch”?

Question

I have always been of the belief that if a method can throw an exception then it is reckless not to protect this call with a meaningful try block.

SO, Why should I not wrap every block in “try”-“catch”?

Answer 1

A method should solely catch an exception if it can handle it in some practical way.

Otherwise, pass it on up, in the belief that a process higher up the call stack can get a sense of it.

 It's a healthy practice to have an unhandled exception handler (with logging) at the highest level of the call stack to assure that any fatal errors are logged.
