The rules for what is valid are specified below. readYear() and readMonth(int) methods Complete the readYear() and readMonth(int) methods. These methods ask the user to input the expiration year and month of their credit card. Each method should contain a loop inside the method so the code repeats until a valid month or year is entered by the user. If the user enters an invalid year or month, print an error message and ask them to try again. The readMonth(int) method reads in the month as a number. A valid month is any number between 1 and 12 (inclusive). A valid year is 2022 or later. readCreditCardNumber() method Complete the readCreditCardNumber() method. This method asks the user to input their credit card number. This method should contain a loop so the code repeats until a valid…
