Java ternary operator with empty clause

This question is more for my curiosity than anything else.

I often employ Java's ternary operator to write shorter code. I have been wondering, however, whether it is possible to use it if one of the if or else conditions are empty. In more details:

int x = some_function();
if (x > 0)
    x--;
else
    x++;

can be written as x = (x > 0) ? x-1 : x+1;

But is it possible to write if (x > 0) x-1; as a ternary expression with an empty else clause?

No, the conditional operator requires three operands. If you wanted, you could do this:

x = (x > 0) ? x - 1 : x;

...but (subjectively) I think clarity suffers.
