About Question enthuware.ocpjp.v11.2.1033 :

When adding throws this also works. Behind the scenes, the compiler replaces a try-with-resources block with a try and finally block. So not mandatory to put a catch or finally block

Please read the problem statement carefully. It is explicitly about the try without resources statement.

Okay clear. Thanks.
