        String str = "includeHelp";
        System.out.println("character at 0 index: " + str.charAt(0));
        System.out.println("character at 1 index: " + str.charAt(1));
        System.out.println("character at 2 index: " + str.charAt(2));
        System.out.println("character at 3 index: " + str.charAt(3));
        System.out.println("character at 4 index: " + str.charAt(4));
