    public static void main(String[] args) {
        int[] array1 = {1, 2};
        for (long x : array1) {
            System.out.println(x);
        }
    }
}

Explanation

In this case array has int elements which are casted implicitly, as there is no precision lost with the cast and there is no compilation exception. The loop prints values in order.
