How do I initialize an ArrayList from a char array?

There is such a code:

List<Character> charArray = new ArrayList<>(Arrays.asList(string.toCharArray()));

But a compile-time error occurs. Why?(maybe because of Character and char?) But why does everything work with int? 

List<Integer> charArray = new ArrayList<>(Arrays.asList(23,22,32));

UPD: Forgot to add without using a loop.

In Java 8, you can do this

List<Character> chars = string.chars().mapToObj(c -> (char) c).collect(Collectors.toList());

List<Character> chars = new ArrayList<>();
for (char c : string.toCharArray()) {
    chars.add(c);
}
