Exception handling try catch inside catch

Question

I recently came across code written by a fellow programmer in which he had a try-catch statement inside a catch!

Please forgive my inability to paste the actual code

Answer 1

Without knowing what the code does it's impossible to say. But it's not unusual to do this.

e.g. if you have to clear up resources whilst handling exceptions, that clear-up code itself may have the capability to throw exceptions.
