Expand
Project 4
as follows:

1. Using the
   BankAccount
   class as a base class, write two derived classes called
   SavingsAccount
   and
   CheckingAccount.


2. Add a new private field
   name
   of type String to the
   BankAccount
   class.
   


3. Add accessor and mutator methods for the
   name
   field.


4. A
   SavingsAccount
   object, in addition to the attributes of a
   BankAccount
   object, should have a
   monthlyInterest
   variable and a method, which adds interest to the account. Assume you are adding the interest accumulated in a month.

//monthlyInterest += (accountBalance * (annualInterestRate / 12))

//accountBalance += monthlyInterest

public void addInterest() {

//code goes here

};

1. The
   CheckingAccount
   class, in addition to the variables of a
   BankAccount
   class, should have an
   overdraftLimit
   variable (default to $50). Ensure that you override methods of the
   BankAccount
   class as necessary in both derived classes.

Create a
Bank
class, which contains an
ArrayList
of
BankAccount
objects called
bankAccounts.
BankAccounts in the array could be instances of the
BankAccount
class, the
SavingsAccount
class, or the
CheckingAccount
class.

Write an
update
method in the
Bank
class. It iterates through each account, updating it in the following ways:

Savings accounts get interest added (via the
addInterest
method)

Checking accounts get a letter sent (System.out.println) if they are in overdraft. (Hint: use
instanceof
operator)

1. The
   Bank
   class requires methods for
   openAccount
   and
   closeAccount.




1. 
   openAccount()
   should ask the user for:




1. his/her name (just first name, no last name)


2. what type of bank account (s)he wishes to open. Options are
   Regular
   Account (BankAccount
   object),
   Savings
   (SavingsAccount
   object) or
   Checking
   (CheckingAccount
   object). Create an object of the appropriate type and add it to
   bankAccounts. Display the account Id after this operation.


3. Initial Balance (minimum $100). Display a message if the user tries to open an account with less than $100 deposit (make sure account does not get created).
   




2. 
   closeAccount()
   should ask the user for his/her name and the account Id and then delete from
   bankAccounts
   the account that matches both the
   name
   and
   accountId. If they have a balance print a message indicating that a check with a balance will be mailed to them (indicate amount).




2. Test all your classes in the
   TestBankAccount
   class. Send all output to the console. Use a
   Scanner
   object to get user responses and
   System.out.println
   to print to the console.

Additional Hints:

Note that the balance of an account may only be modified through the deposit (double) and withdraw (double) methods.

Changes to the original
BankAccount
class should be minimal.

Make sure to test what you have done after each step.

Make sure to include enough testing in
TestBankAccount
to cover all the functionality implemented.
