The operator sometimes known as the ternary operator is actually named the conditional operator. It's of the form

A ? B : C

where A is a Boolean expression, and B and C are expressions either of the same type, or of types such that the type of B can be implicitly converted to the type of C or vice versa.

First A is evaluated; if the result is true then B is evaluated to provide the result. Otherwise C is evaluated to provide the result.

At least, you have left the "why is popular" part unanswered to give the rest of us an opportunity :-) – Konamiman Nov 04 '09 at 15:11

It is popular because it leads to shorter and more readable code. Consider this simple example:

int daysInYear = isLeapYear ? 366 : 365;

instead of

if(isLeapYear) {
   daysInYear = 366;
} else {
   daysInYear = 365;
}
