I found this thread for you:
https://stackoverflow.com/questions/2451650/how-do-i-apply-the-for-each-loop-to-every-character-in-a-string#2451660

String str = "xyz";
for(int i = 0; i < str.length(); i++){
char c = str.charAt(i);
}

or

String str = "xyz";
char arr[] = str.toCharArray();

Better with Streams adopting Functional Programming.

Why?? With arrays you are limited to int size. Streams there are not this limitation, so you can process huge texts even fork in little tasks to process in parallel.

A hint how to start...

https://docs.oracle.com/en/java/javase/15/docs/api/java.base/java/util/regex/Pattern.html#splitAsStream(java.lang.CharSequence)

Stream<String> charStream = Pattern.compile("").splitAsStream("your text");

The magic is made by providing an empty string to Pattern. It splits by chars
