    Can I parse a double into a char?

    I want to print the value that corresponds to the middle of a string using the Math.ceil() method but I only get it to show the value of the index which is 600. But i want to print the actual character which is an 'A'. How can I do this?

    double center = Math.ceil(FileData.length() / 2);
    System.out.println(center);

    What's the purpose of Math.ceil? In this case it has no effect other than turning an int into a double. This is sufficient (to get the middle String position rounded downwards),

    int center = FileData.length() / 2;

    To get the char corresponding to this String position you can use the charAt() method.

    char centerChar = FileData.charAt(center);
