What is the Java ?: operator called and what does it do?
What is this type of code statement called? I've seen it in Java and C++ before, but I can't remember what it is called. int someVariable = (true) ? 1 : 0;

1This is called the 'ternary' operator. Please have a look at http://alvinalexander.com/java/edu/pj/pj010018 – Chetter Hummin Dec 30 '12 at 02:51

To be fair, it can be incredibly difficult to search a general source of information such as wikipedia for a question mark. – competent_tech Dec 30 '12 at 02:55

@competent_tech, that was exactly my problem. Didn't know what to search for. – Emrys90 Dec 30 '12 at 02:57

@Emrys90 you can use [Symbol Hound](http://www.symbolhound.com/?q=%3F%3A) to search these things – New Alexandria Dec 30 '12 at 03:01

Or you could even just type out 'question mark'. When I didn't know what a ternary operator was, that's how I figured it out. – Michael Dec 30 '12 at 03:05

Its ternary operator to avoid line of codes for simple condition checking
int biggerNumber = a > b ? a : b;
even more
int bigNumber = a > b ? (a > c ? a : c) : b > c ? b : c ;
