Question

Is there a way to do the following at the same time?

static final int UN = 0; // uninitialized nodes
int[] arr;

// ... code ...

arr = new int[size];
for (int i = 0; i < 5; i++) {
    arr[i] = UN;
}

Basically, I want to declare arr once I know what its size will be and initialize it to UN without having to loop. So something like this:

int[] arr = new int[size] = UN;

Is this possible?

Thanks.

No, not with the standard libraries. If you write your own functions, though, you can easily do so in a single statement (not instruction; those are different). Mine looks like String[][] strings = Arrayu.fill(new String[x][y], "");

Here’s a link. There’s some junk in there too, though; I just posted a copy of the current source directly without cleaning it up.
