Question
Use the Account class that you created in your previous assignment to model a Bank account. Create two subclasses for Checking and Savings account that extend your Account class from previous assignment. Implement the following in these 2 subclasses:
A Checking account has an overdraft limit (of $5,000), but a Savings account cannot
be overdrawn. Override the withdraw method in these subclasses to take care of the
overdraft restrictions.
All data and methods are inherited from Account class.
Create constructors for both Checking and Savings account. These constructors
should invoke the constructors of their superclass
Change the deposit method in Account class. Create two overloaded deposit methods in Account class such that one of them takes an integer value as the input parameter and the second one takes a double value as the input parameter.
Write a test program (class named TestAccount) that does the following:
a) Creates 2 objects - a Saving Account and a Checking Account. Get user inputs for
account information that is needed to create these 2 objects.
b) Get user input for an amount to be withdrawn from the Checking Account (for example, $2,500) and an amount to be deposited to the Checking Account (for example, $3,000). Make sure the overdraft restrictions work.
c) Similarly, withdraw and deposit from and into the Saving Account also.
d) Finally, print the account information for both the Checking and Saving accounts (i.e., print the current balance (after withdrawal and deposit), the monthly interest,
and the date when these two accounts were created).
Recap of Account class:
Account class has the following data and behavior
An integer data field – accountId, i.e., the account id (default value is 0).
A double data field – balance that stores the current balance for the account (default value
is 0).
A double data field - annualInterestRate (default value is 0).
A Date data field - dateCreated that stores the date when the account was created.
A no-arg constructor that creates a default account.
A 3-arg constructor that creates an account using a specified account ID, balance, and
annual interest rate.
The accessor(get) and mutator(set) methods for accountId, balance, annualInterestRate.
The accessor(get) method for dateCreated.
A method named getMonthlyInterest() that returns the monthly interest.
A method named withdraw that withdraws a specified amount from the account.
A method named deposit that deposits a specified amount to the account.
