public static void main(String[] args) {
    int[] ary1 = {1, 2, 4, 6, 8, 3, 10, 9};
    int[] ary2 = {2, 4, 6, 1, 13, 25, 10};

    Set<Integer> set = new HashSet<Integer>();
    for (int i : ary1) {
        set.add(i);
    }
    for (int i : ary2) {
        set.add(i);
    }
    List<Integer> list = new ArrayList<Integer>(set);
    Collections.sort(list);
    for (int i : list) {
        System.out.print(i + " ");
    }
}
