(1) A public getter method, named GetInterestRate(), that is used to get the value of the private data member interestRate. (2) Override the method MonthlyFees().This method should return a monthly fee of $5.00. (2) Override the DisplayFees() method from the super class to display the following info: account number, interest rate, and monthly fees.Note: Make calls to the super class methods whenever possible.b) From the attached abstract BankAccount class, derive a class calledChecking.The class should contain: (1) A private data member called numChecksWritten of type integer.
