Can I declare and initialize an array with the same instruction in Java?

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

You don't need to initialize them with 0. An int defaults to 0 already.

Just

int[] array = new int[size];

is enough. It gives you an array of zeroes of the given length. If it were an Integer[], it would have been an array of nulls.
