Exclusive or is written as ^, and is true only when the two operands are logically different (one is true and the other is false). (n < 0) ^ (n != 0) will be true when either of the following conditions holds:
n < 0 AND n = 0 (i.e., never)
not(n < 0) AND n != 0 (i.e., n > 0)

May the problem be the Java's nature of the "OR" || which is "Exclusive OR", i.e.
a || b
means that if a is true, b is not evaluated. Maybe you're looking for "Inclusive OR" i.e. if a or b, both getting evaluated, which in Java is:
a | b
Although, frankly, I do not see much of a point for this here...
IMHO,
if( n <\<> 0)
=>
if(n < 0)
in Java will cover both conditions, as the number n can not be sulmonteniously less then 0 and equals to 0.
Yah? Or am I missing something?

Arrgh. I meant to say "whenever n is NOT 0".
