People call it the trinary operator, and it works as a shortcut if-else statement. It basically works like this: Code:| (expression) ? statement1 : statement2; |
|
If expression is true, statement1 will happen and else statement2 will happen. Here is an example:
Code:| String b = (c != 5) ? "c isn't five!" : "c is five!"; |
|
Hope this helps!

But more people call it the ternary operator.
