How can i convert String to Character Stream using streamAPI?

Question

String st = "FindCaptialWords";

Can we convert above string to character stream using StreamApi?

`st.chars()` which gives you an `IntStream` which is equivalent to what a character stream is (there is no `CharStream` in Java). — Kayaman, Jan 05 '22 at 12:32
@DmitriiBykov It won't work _as intended_ returning a single-element stream of `char[]` which is kind of useless. — terrorrussia-keeps-killing, Jan 05 '22 at 12:37
@Olivier Java 8, along with the rest of the Stream API. [Design decisions](https://stackoverflow.com/q/22435833/2541560) behind it. — Kayaman, Jan 05 '22 at 12:45

I just use

Stream<Character> foo = st.chars().mapToObj(c -> Character.valueOf((char) c));

though a stream of codepoints becomes much more useful than a stream of chars as soon as you need to deal with text outside of the BMP since a single char/Character can't hold those values, and so you're back to working with an IntStream as returned by st.codePoints().
