I am using prepared statement for bulk insertion of records. Iam iterating a list which contains values and their dataTypes differ. One of the data type is BigDecimal and when i try to set calling preparedstatement, it is throwing null pointer exception.

My code

                int count = 1;
                for (int j = 0; j < list.size(); j++) {                     
                    if(list.get(j) instanceof Timestamp) {
                        ps.setTimestamp(count,  (Timestamp) list.get(j));       
                    } else if(list.get(j) instanceof java.lang.Character) {
                        ps.setString(count, String.valueOf(list.get(j)));
                    }
                    else if(list.get(j) instanceof java.math.BigDecimal) {
                        ps.setBigDecimal(count, (java.math.BigDecimal)list.get(j));
                    } else {
                        ps.setObject(count, list.get(j));   
                    }                           
                    count++;
                }

I tried 2 ways to convert, casting the object and tried to create a new object of type BigDecimal

ps.setBigDecimal(count, new BigDecimal(list.get(j).toString));

both donot solve my problem. It is throwing null pointer exception.

help is appreciated.

Thanks
