PLEASE HELP WITH THIS JAVA PROGRAM. Creating a small credit card accounting system program that uses hashtables. The database will keep track of accounts for a company that issues credit cards and allows a restricted set of database operations. The program must also provide a nice interface to present to the user: The data that will be tracked for an account is the following: 1. the credit card number (sixteen digits), this will be the key field that must be unique. 2. the name of the card holder, 3. the credit limit for that card (a double), and 4. the current balance on that card (a double). The operations that the program will support are: 1. account creation, a. there cannot be two accounts with the same key added to the system 2. account deletion, 3. credit limit adjustment, a. increase or decrease a users credit limit 4. Making a purchase on the card. a. Only runs valid purchase. Otherwise prints an error message 5. Print out a single account a. Use a similar format as used for printing all accounts 6. Print out all accounts a. Should include evenly spaced columns (use String.format ) b. Everything should be in alphabetical order based upon the cardholders name (try to look at Collections.sort ) c. Should include: the name, card number , credit limit and balance 7. Run a Database operations file of actions a. This action will ask the user for an input file that contains a list of actions the program must execute. The format of this file is discussed later. b. No user input is required when running each individual action 8. Everything is run until the user requests to exit For a fully useful program, other operations (especially accepting payments against the balance) would be required but the logic of their design is similar to the ones listed and thus they are not included in this assignment. You will be required to read in from a file. The input file are on BB. November 21, 2017 [COMP 2503 ASSIGNMENT 5 - HASHING] Page 2 of 3 The Database Operations File To allow for the scripted input of actions against the database you will read the operations to perform from a file. You may assume that the file is well formed. The operations will be specified on a single line. The arguments to the operation will be on subsequent lines. There will be no leading or trailing whitespace for any of the fields in the file. Credit card numbers will be formatted as 16 digit numbers. cre Add a record to the file. The record information will occupy the next 4 lines in the order: credit card number, name of card holder, credit limit, and balance. del Mark a record as deleted. The following line will contain the credit card number of the record to be deleted. lim Change the credit limit field in the record specified by the credit card number given. The line following the lim command will contain the credit card number and the line after the credit card number will contain the new limit. pur Cause a purchase transaction to occur if the additional information specifies a valid purchase operation. Otherwise, an error message will be displayed. The line following the pur command will contain the credit card number and the line after the credit card number will contain the amount of the purchase.

This is the test file.
