There is no right answer in the list of answers.

I ran the programm. It did not compile with error: unreported exception Exception; must be caught or declared to be thrown
doA(15); // 3

Which is correct, becuase Exception is not decalared in method doB.

So answer list should be corrected.

The question is fine. You are not trying the code exactly as given.

No, I run code exactly as it given.

You must be making some mistake. I have verified that the question is correct. It doesn't compile.

Code: Select all

A.java:9: error: unreported exception Exception; must be caught or decla
red to be thrown
            doA(15); // 3
               ^
1 error

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - unreported exception java.lang.Exception; must be caught or declared to be thrown
at a.A.doB(A.java:12)
at a.A.main(A.java:20)
Java Result: 1

I use NetBeans. The same result.

The answer now is: "This will compile if throws Exception is added at line //2 as well as //4."

In my opnion it should be: "It will not compile. The Exception is thrown at line //3 as well as //4."

Am I correct?

It is really difficult to comment on error messages displayed by IDEs. Please use the command line. That is what matters for the exam as well. As I mentioned before, the question and its explanation are correct. Please try it exactly as given.
