What the compiler cares about is that control can reach later statements even if previous statements throw an exception. The compiler normally assumes that if one statement throws an exception, the next statement won't be executed, so an unassigned variable won't be read. Adding a 'catch' will allow control to reach later statements - it's the catch that matters, not whether the code in the try block throws. | |
