Why can I pass 1 as a short, but not the int variable i?

Question

Why does the first and second Write work but not the last? Is there a way I can allow all 3 of them and detect if it was 1, (int)1 or i passed in? And really why is one allo

Answer 1

I believe it is because you are passing in a literal/constant in the first two, but there is not automatic type conversion when passing in an integer in the third.

Edit: Someone beat me to it!
