Equivalent of 'null' for integers?

Question

I was wondering if the integer data type has a value that is the equivalent to 'null'?

Answer 1

yeah don't use 0 0 is a number null is nothing.
The best thing to do if you don't want it to be a
a NPE (NullPointerException) would be to do what was
suggested but use a negitive number (providing your
numbers are supposed to be positive).No.
Don't avoid null just to avoid NPE if null best represents what you're trying to do. Use null, test your code thoroughly to make sure that null is handled properly when it occurs (and "handling it properly" may mean throwing NPE--exceptions aren't evil), and document what null means and how it's handled so that users of your class can use it properly.
