Wondering is there more simple way than computing the character count of a given string as below?

    Map ch         


        

Answer 1

Hope this help : Java 8 Stream & Collector:

    String word = "AAABBB";
    Map charCount = word.chars().boxed().collect(Collectors.toMap(
                    k -> Character.valueOf((char) k.intValue()),
                    v -> 1,
                    Integer::sum));
    System.out.println(charCount);

Output:
    {A=3, B=3}
