> While fetching data from ResultSet in JDBC. I got the null pointer. Details -
> java.lang.NullPointerException

> Below mentioned method is throwing null pointer becaue getObject(rowOffset) returns null for null values & null.toString() is throwing null pointer.
> @Override
> public String getString(int rowOffset) throws InvalidAccessException{
> return getObject(rowOffset).toString();
> }
> It should be like:
> @Override
> public String getString(int rowOffset) throws InvalidAccessException{
> return getObject(rowOffset)==null? null:getObject(rowOffset).toString();
> }
