Java: Ternary with no return. (For method calling)

I was wondering if it was possible to do a ternary operation but without returning anything.

If it's not possible in Java is it possible in other languages, if so which ones apply?

name.isChecked() ? name.setChecked(true):name.setChecked(false);
Solution

  • No, you can't. But what's the point of this over an if-else statement? Are you really trying to save 7 characters?

    if (name.isChecked()) {
    name.setChecked(true);
} else {
    name.setChecked(false);
}

    or if you prefer bad style:

    if (name.isChecked()) name.setChecked(true); else name.setChecked(false);

    Never mind the fact that you can just do (in this case):

    name.setChecked(name.isChecked());

    The point of the ternary or "conditional" operator is to introduce conditionals into an expression. In other words, this:

    int max = a > b ? a : b;

    is meant to be shorthand for this:

    int max;
if ( a > b ) {
    max = a;
} else {
    max = b;
}

    If there is no value being produced, the conditional operator is not a shortcut.
