        String number = "12345.00000";

        // Split with error
        String splitError = number.split(".")[0];
        System.out.println("splitNumber " + splitError);

        // Correct way to split by dot(.)
        // "." is a special character. You have to use "\\." to escape this character
        String splitCorrect = number.split("\\.")[0];
        System.out.println("splitNumber " + splitCorrect);
