> 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();
>   }
