In IDEA, how to add a space between code & comment automatically?

Question

---

Example

Example A:

T result = (T) node.value; // keep return value,

There is a space between ; and //

Example B:

if (k < 0 || k > size) // out of range,
    return false;

There is a space between ) and //.

Example C:

if (size == 0 || k == size) { // append at end,
    append(value);
    return true;
}

There is a space between { and //.

I searched on Google, and found this post: Is there any way to have the line comment shortcut add a space after // in WebStorm?

The link only tells how to add a space after //, and that's the default behavior.

I didn't found any solution.

• How to let IDEA add spaces from the above examples automatically on formatting?

(BTW, I am not saying that it's better, I just personally prefer to that, and trying to get it done.)
