charType -> integer number

class Example {
    public static void main(String[] args) {
         char charNine = '9';
         int nine = charNine - '0';
         // -> nine;
    }
}

String -> splice?

class Example {
    public static void main(String[] args) {
         String exam = "adcd";
         StringBuilder builder = new StringBuilder(exam);
         builder.deleteCharAt(1); //like Splice
    }
}
