@p3t0r: I just realized that your way won’t work because there is no way the main method know that this method will ALWAYS throw exception. The result is: it will ask for return statement, which I don’t want here.

Generic is very nice No more casting with ArrayList and Vector

Good idea, but my point is that this is just an example on how to do it.

Oops, sorry for the markup issues, it should be:

public E logAndThrowException(E e) throws E {
log.warn(e);
throw (e);
}

Why didn’t you create a logAndThrow method? And why didn’t you specify a supertype for E?

public E logAndThrowException(E e) throws E {
log.warn(e);
throw (e);
}
