Enthuware

this is the most ambiguous i have seen, ofc thanks a lot to enthuware for preparing against Sauron Oracle

Why do you think this question is ambiguous?

because it said no compile error and i assimilated it with also no exception

Exceptions can only be thrown at run time. But the code has to compile first before it can be run. Identifying issues that arise at compile time is also important for the exam.
