Narrowing + Boxing

[Adolfo Eloy]

I'd like to know what happens when the compiler interprets the declaration below:

Short s = 200;

I thought a int literal 200 couldn't be converted to a Short but only to Object or Integer.
I've tried to search on JVM spec but I couldn't find any kind of answer to this.

Reading the K&B, I understood that we can't Widen and Box, so why we can Narrow and Box?

Thanks!

See section 5.2 of the Java language specification. You want to go about 3 paragraphs down, to a paragraph that starts out with "in additon...". The second bullet point down talk about boxing and compile time constants.

Hello Henry Wong!
I've searching on JVM spec instead of Java Language Spec. :P

Like you said, section 5.2 describes exactly what I was searching for.

Thank you!
