In Java 8, CharSequence::chars method provides a one-line way to convert a String into List<Character>:

myString.chars().mapToObj(c -> (char) c).collect(Collectors.toList());

如果你需要转换 char [] 到列表<字符> ，您可以先从它创建字符串，然后应用上述解决方案。虽然它不太可读和漂亮，但它会很短。

And if you need to convert char[] to List<Character>, you might create a String from it first and then apply the above solution. Though it won't be very readable and pretty, it will be quite short.
