Am I missing something, or do varargs break Arrays.asList?

Question

  private void activateRecords(long[] stuff) {
    ...
    api.activateRecords(Arrays.asList(specIdsToActivate));
  }

Shouldn\'t this call to Array

Answer 1

Autoboxing cannot be done on arrays. You are allowed to do:

private List<Long> array(final long[] lngs) {
    List<Long> list = new ArrayList<Long>();
    for (long l : lngs) {
        list.add(l);
    }
    return list;
}

or

private List<Long> array(final long[] lngs) {
    List<Long> list = new ArrayList<Long>();
    for (Long l : lngs) {
        list.add(l);
    }
    return list;
}

(notice that the iterable types are different)

e.g.

Long l = 1l;

but not

Long[] ls = new long[]{1l}

Answer 2

That's because long[] and Long[] are different types.

In the first case T is long[], in the second T is Long.

How to fix this? Don't use long[] in the first place?
