Question

Answer 1

The Java compiler is too stupid to realize that in every situation, one of your conditions will be satisfied. It sees the if statements and thinks that it is possible that none of them will be satisfied. You can add a return at the end of the method that indicates an error case, you can throw an exception, or you can assert false.
