FirstName_LastName_PinTester Class The National Commerce Bank has hired you as a contract programmer. Your first assignment is to write a class that will be used by the bank's automated teller machines (ATMS) to validate a customer's personal identification number (PIN). Your class, which will be named FirstName_LastName_PinTester, will be incorporated into a larger program that asks the customer to input hìs or her PIN on the ATM's numerìc keypad. (PINS are multi-digit numbers. The program stores each digit in an element of an int array.) The program also retrieves a copy of the customer's actual PIN from a database, as an int array. If these arrays match, then the customer's identity is validated. FirstName_LastName_PinTester class fields Field Name Description This field should be an int array reference variable. It will be used to reference an array containing the PIN digits entered by the user. This field should be an int array reference variable. It will be used to reference an array containing the valid PIN digits retrieved from the database. userPIN validPIN FirstName_LastName_PinTester class methods Method Description The constructor is to accept references to two in t arrays as arguments. The array referenced by the first argument will contain the numbers entered by the customer. The array referenced by the second argument will contain the numbers retrieved from the bank's database. The constructor should create Constructor two arrays and reference them by the userPIN and validPIN fields. Then, it should copy the contents of the arrays passed as arguments to the userPIN and validPIN arrays. This boolean function should return true if the userPIN and validPIN arrays are identical. Otherwise, it should return false. isValid FirstName_LastName_PinTesterDemo Class This is the main/driver program that uses methods built in the FirstName_LastName_PinTester class. This program tests the FirstName_LastName_PinTester.isValid method by calling it several times with various arguments.
