BankAccount and SavingsAccount Classes

Design an abstract class named BankAcccount to hold the following data for a bank account:

-Balance
-Number of deposits
-Number of withdrawals
-Annual interest rate
-Monthly service charges

The class should have the following methods:

Constructor: The constructor should accept arguments for the balance and annual interest rate.

deposit: A method that accepts an argument for the amount of the deposit. The method should add the argument for the amount of the deposit. The method should add the argument to the account balance. It should also increment the variable holding the number of deposits.

withdraw: A method that accepts an argument for the amount of the withdrawal. The method should subtract the argument from the balance. It should also increment the variable holding the number of withdrawals.

calcInterest: A methodthat updates the balance by calculating the monthly interest earned by the account ,and adding this interest to the balance. This is performed according to the following formulas: Monthly InterestRate = (Annual Interest Rate / 12) Monthly Interest = Balance *Monthly Interest Rate Balance = Balance + MonthlyInterest

monthlyProcess: A method that subtracts the monthly service charge from the balance, calls the calc Interest method, and then sets the variables that hold the number of withdrawals, number of deposits, and monthly service charges to zero.

Next, design a SavingsAccount class that extends the BankAccount class.The SavingsAccount class should have a status field to represent an active or inactive account. If the balance of a savings account falls below $25, it becomes inactive. (The status field could be a boolean variable.) No more withdrawals may be made until the balance is raised above $25, at which time the account becomes active again. The savingsaccount class should have the following methods:

withdraw: A method that determines whether the account is inactive before a withdrawal is made. ) No withdrawal will be allowed if the account is not active.) A withdrawal is then made by calling the superclassversion of the method (assuming it is allowed).

deposit: A method thatdetermines whether the account is inactive before a deposit ismade. If the account is inactive and the deposit brings the balanceabove $25, the account becomes active again. A deposit is then madeby calling the superclass version of the method.

monthlyProcess: Beforethe superclass method is called, this method checks the number of withdrawals. If the number of withdrawals for the month is more than 4, a service charge of $1 for each withdrawal above 4 is added to the superclass field that holds the monthly service charges.(Don

Explanation / Answer

// Design an abstract class named BankAcccount to hold the following data for a bank account:
public abstract class BankAccount
{
// -Balance
private double balance;
// -Number of deposits
private int numDeposits;
// -Number of withdrawals
private int numWithdrawals;
// -Annual interest rate
private double annualInterest;
// -Monthly service charges
private double serviceCharge;

// Constructor: The constructor should accept arguments for the balance and annual interest rate.
public BankAccount(double balance, double annualInterest)
{
this.balance = balance;
this.annualInterest = annualInterest;
}

// deposit: A method that accepts an argument for the amount of the deposit. The method should add the argument for the amount of the deposit. The method should add the argument to the account balance. It should also increment the variable holding the number of deposits.
public void deposit(double amount)
{
balance += amount;
numDeposits++;
}

// withdraw: A method that accepts an argument for the amount of the withdrawal. The method should subtract the argument from the balance. It should also increment the variable holding the number of withdrawals.
public void withdraw(double amount)
{
balance -= amount;
numWithdrawals++;
}

// calcInterest: A methodthat updates the balance by calculating the monthly interest earned by the account ,and adding this interest to the balance. This is performed according to the following formulas: Monthly InterestRate = (Annual Interest Rate / 12) Monthly Interest = Balance *Monthly Interest Rate Balance = Balance + MonthlyInterest
public void calcInterest()
{
double monthlyInterest = annualInterest/12;
balance += monthlyInterest*balance;
}

// monthlyProcess: A method that subtracts the monthly service charge from the balance, calls the calc Interest method, and then sets the variables that hold the number of withdrawals, number of deposits, and monthly service charges to zero.
public void monthlyProcess()
{
balance -= serviceCharge;
calcInterest();
numWithdrawals = 0;
numDeposits = 0;
serviceCharge = 0;
}

// accessors
public double getBalance()
{
return balance;
}
public int getNumDeposits()
{
return numDeposits;
}
public int getNumWithdrawals()
{
return numWithdrawals;
}

// mutator for service charge
protected void addServiceCharge(double amount)
{
serviceCharge += amount;
}
}

// Next, design a SavingsAccount class that extends the BankAccount class.The SavingsAccount class should have a status field to represent an active or inactive account.
public class SavingsAccount extends BankAccount
{
private boolean active;

public SavingsAccount(double balance, double annualInterest)
{
super(balance, annualInterest);
active = balance >= 25;
}

// withdraw: A method that determines whether the account is inactive before a withdrawal is made. ) No withdrawal will be allowed if the account is not active.) A withdrawal is then made by calling the superclassversion of the method (assuming it is allowed).
public void withdraw(double amount)
{
if(active)
super.withdraw(amount);
active = (getBalance() >= 25);
}

// deposit: A method thatdetermines whether the account is inactive before a deposit ismade. If the account is inactive and the deposit brings the balanceabove $25, the account becomes active again. A deposit is then madeby calling the superclass version of the method.
public void deposit(double amount)
{
super.deposit(amount);
active = (getBalance() >= 25);
}

// monthlyProcess: Beforethe superclass method is called, this method checks the number of withdrawals. If the number of withdrawals for the month is more than 4, a service charge of $1 for each withdrawal above 4 is added to the superclass field that holds the monthly service charges.(Don
