Explanation

In Java, a top-level class cannot be private - only public, abstract, and final are allowed. The code attempts to declare "private class AQuestion" which violates this rule. Therefore, the code does not compile. If it were a valid inner class, the overload resolution would select the more specific String method for null argument.
