Question ID : com.enthuware.ets.scjp.v5.2.200



The above code compiles prefectly without any error...

My question is the below method says it returns int, and it doesn't return anything......how does this pass the compiler..??

If you make a return statement there, the compiler complains that the
code is not reachable. Code below the throw statement is not reachable.
There is no error irrespective that the method says that it returns int,
because the code throws the exception explicitly using "throw".


If there is something like
int a=10;
int b=a/0;
then you must return the int from the method because there is exception (divide by zero) that is not known until the line b=a/0 is executed at run time.



Thanks,
