What's the difference between XOR and NOT-EQUAL-TO?

Question

My question uses Java as an example, but I guess it applies to probably all.

Is there any practical difference between the XOR operator (^ in Java) and

Answer 1

With boolean values, there should be no difference. You should choose whichever is more appropriate for your sense of operation.

Example:

bool oldChoice = ...;
bool newChoice = ...;
if (oldChoice != newChoice)
    ...

Here XOR would give the same result, but will not reflect the real code intention.
