    public static void main(String[] args)  {

        boolean passed = false;

        try {

        }
        catch (Exception e) {

Comments
EVALUATION Few methods like updateDate() had not been modified to check for null. It is not an issue with updateString(). This has been fixed.

EVALUATION Fixed. If Range has not been defined, all the rows can be updated.
