This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
and I got the same answer as the book, 4 3. However, I don't understand why the answer is not 3 3. Since s is of type Short, couldn't you box short to Short, then widen Short to Integer? The only answer I can think of is maybe because Short is now an object not a primitive, it is a subclass of Number, not Integer? Is that correct?
