In this project, you are assisting an investigation. The investigator asked you to help him determine the validity of credit card numbers located in a case of Mobius Duck, case number 20150510-001. Your task is to: Read the data listed below Data to Evaluate from a file.

Evaluate each number to see if they are representing a possible credit card number.

Validate each credit card number to see if they are a valid number.

Store the valid numbers and invalid numbers in a separate array.

Write the contents of validated credit card number array into a file called valid_cards.txt.

Write the invalid credit card number array to a file called invalid_numbers.txt.

Make sure to include the issuer for each group of credit card numbers identified.

Your application should work with any number of credit card entries. Turn in: Source code ( .java ) files of all classes and driver class.

Completed UML for application classes.

How to validate Credit Card Numbers? Most credit card number can be validated using the Luhn algorithm, which is more or a less a glorified Modulo 10 formulal! The Luhn Formula: Drop the last digit from the number. The last digit is what we want to check against Reverse the numbers Multiply the digits in odd positions (1, 3, 5, etc.) by 2 and subtract 9 to all any result higher than 9 Add all the numbers together The check digit (the last number of the card) is the amount that you would need to add to get a multiple of 10 (Modulo 10) . Luhn Example: Steps Total Original Number: Drop the last digit: Reverse the digits: Multiple odd digits by 2: 10 8 18 9 16 6 16 5 14 3 14 6 10 5 8 Add digits from line above 1 8 9 9 7 6 7 5 5 3 5 6 1 5 8 Add all numbers: Mod 10: 85 (85+X) modulo 10 0, thus X-5 (last digit of card) List of credit card number formats Starts With (IIN Range)Length (Number of digits) Credit Card Issuer American Express Diners Club - Carte Blanche Diners Club- International Diners Club - USA & Canada 34, 37 300, 301, 302, 303, 304, 305 36 54 6011, 622126 to 622925, 644, 645, 646, 647, 648, 649, 65 637, 638, 639 3528 to 3589 6304, 6706, 6771, 6709 5018, 5020, 5038, 5893, 6304, 6759, 6761, 6762, 6763 51, 52, 53, 54, 55 4 4026, 417500, 4508, 4844, 4913, 4917 16 15 14 14 16 16 16 16 16-19 Discover InstaPayment JCB Laser Maestro MasterCard Visa Visa Electron 16-19 16-19 13-16
