What is the Java ?: operator called and what does it do?

Question

I have been working with Java a couple of years, but up until recently I haven\'t run across this construct:

int count = isHere ? getHereCount(index) : getAw         


        

Answer 1

int count = isHere ? getHereCount(index) : getAwayCount(index);

means :

if (isHere) {
    count = getHereCount(index);
} else {
    count = getAwayCount(index);
}
