Sorry for the Retrobump, but this is now really easy!

You can do this easily in Java 8 using Streams! Try this:

String string = "testingString";
List list = string.chars().mapToObj((i) -> Character.valueOf((char)i)).collect(Collectors.toList());
System.out.println(list);

You need to use mapToObj because chars() returns an IntStream.
