Subject: [jdjlist] Re: In Java is this a valid expression (if( n <\<> 0 ) )Actually the term "Exclusive OR" means something else (I have never heard the term "Inclusive OR" used).The fact that Java only evaluates the right hand side operand of the Conditional-Or operator if it is necessary to determine the outcome is colloquially called "lazy evaluation" I believe. See section 15.23 of the JLS for further details.The exclusive-or operator is actually ^ (hat). It only evaluates to true if both operands are different (ie. one true and one false). If both operands are the same (ie. both true or both false) then it evaluates to false. See section 15.22.2 of JLS on this one.Cheers,Craig____________________________________________________-----Original Message-----

Subject: [jdjlist] Re: In Java is this a valid expression (if( 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".
