Try Catch Finally

In case of sudden doubts, here are few pointers from specifications:

A try statement with a finally block is executed by first executing the try block. Then there is a choice:

• If execution of the try block completes normally, then the finally block is executed, and then there is a choice:
• If the finally block completes normally, then the try statement completes normally.
• If the finally block completes abruptly for reason S, then the try statement completes abruptly for reason S.
• If execution of the try block completes abruptly because of a throw of a value V, then there is a choice:
• If the run-time type of V is assignable to the parameter of any catch clause of the try statement, then the first (leftmost) such catch clause is selected. The value V is assigned to the parameter of the selected catch clause, and the Block of that catch clause is executed. Then there is a choice:
• If the catch block completes normally, then the finally block is executed. Then there is a choice:
• If the finally block completes normally, then the try statement completes normally.
• If the finally block completes abruptly for any reason, then the try statement completes abruptly for the same reason.
• If the catch block completes abruptly for reason R, then the finally block is executed. Then there is a choice:
• If the finally block completes normally, then the try statement completes abruptly for reason R.
• If the finally block completes abruptly for reason S, then the try statement completes abruptly for reason S (and reason R is discarded).
• If the run-time type of V is not assignable to the parameter of any catch clause of the try statement, then the finally block is executed. Then there is a choice:
• If the finally block completes normally, then the try statement completes abruptly because of a throw of the value V.
• If the finally block completes abruptly for reason S, then the try statement completes abruptly for reason S (and the throw of value V is discarded and forgotten).
• If execution of the try block completes abruptly for any other reason R, then the finally block is executed. Then there is a choice:
• If the finally block completes normally, then the try statement completes abruptly for reason R.
• If the finally block completes abruptly for reason S, then the try statement completes abruptly for reason S (and reason R is discarded).
