Objective Multiple Dictionaries for database 1 points Use UA

Objective: Multiple Dictionaries for database (1 points)

Use UALdictionary.java to create two Dictionaries and allows user to retrieve the employee record by Key of either dictionary. The employee.txt contains data records of all employee.

Dictionary one will use SSN field which is the fourth field of the data field on the record as Key.

Dictionary two will use Name field which is the first field of the data field on the record as Key.
