How do I convert int[] into List<Integer> in Java?

Of course, I'm interested in any other answer than doing it in a loop, item by item. But if there's no other answer, I'll pick that one as the best to show the fact that this functionality is not part of Java.

There is no alternative for transforming from int[] to List<Integer> as Arrays.asList doesn't trade with boxing and will just generate a List<int[]> which isn't what you require. You have to produce a utility method.

int[] ints = {1, 2, 3};

List<Integer> intList = new ArrayList<Integer>();

for (int i : ints)

{

    intList.add(i);

}
