Hello, I am working in java and wondering why my program isn't working. I will attach the criteria and code below. I have attached my error.

Criteria

------------

Inventory Update program.

The first set of records is the master file which reflects an item inventory at the start of the business day. Each master file record contains a part number and a corresponding item stock quantity. Let us assume that the master file contains no more than 5 records.

The second set of records reflects the transactions for each of various items during that day. Transaction records contain have the same format as the master file records: they contain the item number and the corresponding total number of items sold that day. There is unknown number of such transaction records in the input file.

Write a program to update the master file against the transaction file to produce the new master file at the end of the day. A record notice should accompany any item number for which fewer than 10 items remain in the stock.

                       Current Inventory

Item No.                              Quantity

444                                        40

111                                        30

222                                        15

134                                        20

353                                          5

Sold in a day.

134                                        03

111                                        29

353                                        02

222                                        10

Final output should be

Item No.                            Quantity

444                                        40

111                                          1   reorder

222                                          5   reorder

134                                        17

353                                         3    reorder

I do not understand why my code does not work.
