Defining a Advanced(-ish) Variable via Java?

Question

I've seen Integers set queerly such in programs i've checked out.

I tried searching some reference over it, but I have failed to get the correct terms.

This is what It looks like:
int example = exampl : (exampl : (ausdn : ?));

Or so...

Could anyone link me a reference or explain in-depth on how it works?
I do my daily findings, and learn over it.

If you're talking about conditional expressions, the form is as follows:

(A?B:C)

where A is a boolean expression, B is the result value if A is true, and C is the result value if A is false (in general, B and C will be of the same type; the compiler may even insist on it). This syntax may be combined with other expressions however you like.

If you simply say:

D E=(A?B:C);

where D is a type and E is an identifier, this is considered equivalent to writing:

D E;
if(A)
{
E=B;
}
else
{
E=C;
}

However, as noted above, you may freely combine conditional expressions with other expression syntax.

I think you mean a ternary operator.
It's essentially a short hand way of writing an if-else statement.

Consider the following code:
