Question

Design and implement the following 3 classes with the exact fields and methods (these names and caps exactly): 1. An abstract class named BankAccount (java file called BankAccount.java) Description Filed/Method Balance NumberDeposits NumberWithdrawals AnnualInterestRate MonthlyServiceCharge BankAccount SetHonthlyServiceCharges A method that accepts the monthly service charges as an argument and set the field value GetBalance GetNum berDeposits GetNum berWithdrawals GetAnnualinterestRate GetMonthlyServiceCharge A method that returns the monthly service charge Deposit field for the bank account balance A field for the number of deposits this month A field for the number of withdrawals this month A field for the annual interest rate A field for the monthly service charge A constructor method that accepts as arguments the balance and the annual interest rate A method that returns the bank account balance A method that returns the number of deposits this month ethod that returns the number of withdrawals this month ethod that returns the annual interest rate A method that accepts the amount of the deposit as an argument, add the value of that argument to the account balance, and increment the variable holding the number of deposits. Withdrawal method that accepts the amount of the withdrawal as an argument, subtracts that argument value from the balance, and increment the value holding the number of withdrawals CalculateInterest method that updates the balance Monthlylnterest Balancearoar Monthly A method that subtracts the monthly service charges from the balance, callas the Calculatelnterest method to calculate the interest, and then sets to 0 the variables for NumberDeposits, NumberWithdrawals, and by calculating the monthly interest earned by the account ( and adding this interest to the balance (BalanceBalance+ MonthlyProcess MonthlyServiceCh 2. A class named SavingsAccount (java file called SavingsAccount.java) that extends the BankAccount class. Filed/Method Description Status A private (Boolean) field that holds the account status: if it is active or inactive. If the balance of the account falls below 525 the account becomes inactive. No withdrawals can be made from an inactive account. SavingsAcot A constructor method that accepts as arguments the account balance, the annual interest rate, and the monthly service charge. The constructor should call the superclass constructor and, based on the account balance, the constructor should set the account Status to true or false Deposit A method that accepts the deposit amount as an argument, calls the superclass version of the Deposit method to make a Withdrawal A method that accepts the withdrawal amount as an argument, checks if the status of the account is active, and, if that is true, calls the superclass version of the Withdrawal method, to make a withdrawal from the account. The method should update the Status if the balance goes under $25 MonthlyProcess A method that does the monthly process based on the number of withdrawals from the account. If the number of withdrawals for the month is less or equal to 4, the method calls the superclass version of the Monthly Proces method, to do the monthly process. If the number of withdrawals for the month is more than 4, then a service charge of $1 for each withdrawal above 4 (e.g. $1 for 5, S2 for 6, etc.) is added to the superclass field that holds the monthly service charge (using the superdass SetMonthlyServiceCharges). Then, the method calls the superclass version of the MonthlyProcess method, to do the monthly process. 3. A driver class/program/project called MainAssignment in the same project as the BankAccount.java and SavingsAccount.java that create one or more SavingsAccount objects and demonstrate the methods GetBalance, GetNumberDeposits, GetNumberWithdrawals, GetAnnualinterestRate, GetMonthlyserviceCharge, Deposit, Withdrawal, Calculatelnterest, and MonthlyProcess t particular SavingsAccount object.
