Java: how to split a string when you want a delimiter of nothing

Question

Say I have string A = "AAaabb";

How do I split this string when there are no spaces, so I can't use space as a delimiter. Is there a like null delimiter, where it just splits all characters?

basically I want an array with each individual character [A, A, a, a, b, b]

@sleepToken splitting by "" adds an empty char in the array. i.e if you call s.split("").length, you'll get 7 instead of 6. — BluRe.CN, Dec 04 '19 at 18:16
@BluRe.CN While I'm sure `toCharArray()` is the preferred method,`s.split("");` does not behave this way for me . — sleepToken, Dec 04 '19 at 18:18
Does this answer your question? [Split string into array of character strings](https://stackoverflow.com/questions/5235401/split-string-into-array-of-character-strings) — Kalana, Dec 04 '19 at 18:20
@BluRe.CN it looks like `s.split("");` works in java 8+, so perhaps we are both correct — sleepToken, Dec 04 '19 at 18:21
@HappyCoder Just be aware that `split("")` works this way only from Java 8 and later versions. Relevant question on that subject: [Why in Java 8 split sometimes removes empty strings at start of result array?](https://stackoverflow.com/q/22718744) — Pshemo, Dec 04 '19 at 18:37

Try this!

Use A.split(""); //A is your array

String A = "AAaabb";
String Array[] = A.split("");
System.out.println(Array[0]); // print A

just do this :

    String input =  "AAaabb";
    char[] output;
    output = input.toCharArray();

public static void main(String[] args) {
    String s = "AAaabb";
    String[] array = s.split("");

    for (String string : array) {
        System.out.println(string);
    }
}

result: A A a a b b
