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

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 shortcut for converting from int[] to List as Arrays.asList does not deal with boxing and will just create a List which is not what you want. You have to make a utility method.

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

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

    for (int index = 0; index < ints.length; index++)
