Question

a) Create a class named BankAccount with fields that hold an account number, the owner's name, and the account balance. Include a constructor that initializes each field to appropriate default values. Also include methods to get and set each of the fields. Include a method named deductMonthlyFee() that reduces the balance by $4.00. Include a static method named explainAccountPolicy() that explains that the $4 service fee will be deducted each month.
