About Question enthuware.ocajp.i.v7.2.1361 :

[The_Nick]

Hi,
I would like to point out that there is also this little trick besides the question scope.

Code: Select all

public static int doIt() throws Exception{
      throw new Exception("Forget It");
   }

If the question were something like: The method doIt() does not compile. true or false.?
What would you have replied?

Fantastic question so you can exercise also in tricky unreachable code things.
In this case the "return" statement must be omitted either before or after the Exception throwing itself.
If "return" had been used in either above or below the "throw new Exception" statement it would not have compiled at all as it would have given a compilation error due to unreachableness of the code.

This question is quite similar to enthuware.ocajp.i.v7.2.1260; yet one of them is categorized into section 03 (operators) and the other into section 08 (exceptions)

[Roibeard]

public static int doIt() throws Exception{
System.out.println("Forget It");}
}

Won't compile because "This method must return a result of type int."
Why doesn't

public static int doIt() throws Exception{
throw new Exception("Forget It");}
}

have the same issue?

Just the way the language designers chose to frame the language rules. The compiler knows that this call will always end abruptly and a return is not required.

Ok,
thank you.

I actually answered right (false) because I though it wasn't going to compile... a great question indeed, I learnt something new!

[enthunoob]

It wont even compile cause the top line writes a comment with only one slash. Right?

[admin]

Not really. It is a division operator. Can you post a screen shot of what you see?
