multiple checks in a if statement

Question

In java is there a faster way of doing this?

if (keyCode != 66 && keyCode != 8 && keyCode != 21 && keyCode != 22) {

}

keyCode is an int.

Answer 1

Faster? Is it too slow for you? Don't play optimizer. Write readable code and leave microoptimizations to the optimizer. Premature optimization is the root of all evil

Edit after josh's comment:

If you have really many of them, put them in a container (such as a set or an array) and find keyCode in it. If you found it, then your condition is false. Otherwise it's true.

As per Dave's comment:

if(!MyCodesSet.Contains(keyCode)){
}
