Nope. It does not.

It means a primitive or String literal, an expression involving constants, or a 'final' variable initialized with a constant expression. It need not be 'static'.

Lipska, you should study Java before blathering. You make no sense.

If you don't even know what a "constant" is in Java, you need to study more.

So don't say 'static', duh.

C'mon, learn Java already!

Right. So?

Disingenuous. Work from the *actual* definition of "constant" in Java, please.

And that would be a "constant variable" in Java.

Yes. That's in the JLS.

This has nothing to do with what I said, which was "use a constant".

Irrelevant. Ignored.

Actually, he'd use the Java definition, not the mistaken one.

Yeah, right.

You're wrong because you aren't talking about Java constants.

I said to use a constant. Let's address that advice, hm?
