A-->Defining the Superclass (The Account class)
Design a class named Account that contains:
A private int data field named id for the account (default 0).
A private double data field named balance for the account (default 0.0).
A private double data field named annualInterestRate that stores the current interest rate
(default 0.0).
A private Calendar data field named dateCreated that stores the date when the account was
created. Use Calendar type object.
A no-arg constructor that creates a default account.
A constructor that creates an account with the specified id, initial balance and annual interest
rate. Within the constructor, assign the value of dateCreated using Calendar.getInstance().
The accessor and mutator methods for id, balance, and annualInterestRate.
The accessor method for dateCreated.
A method named getMonthlyInterestRate() that returns the monthly interest rate.
monthlyInterestRate is annualInterestRate / 12. Note that annualInterestRate is a
percentage, e.g., like 4.5%. You need to divide it by 100
The method getMonthlyInterestAmount() is to return monthly interest amount, not the
interest rate. Monthly interest amount is balance * monthlyInterestRate.
A method named withdraw that withdraws a specified amount from the account.
A method named deposit that deposits a specified amount to the account.
Write a test program that creates an Account object with an account ID of 1122, a balance of
$20,000, and an annual interest rate of 4.5%. Use the withdraw method to withdraw $2,500, use the
deposit method to deposit $3,000, and print the balance, the monthly interest, and the date when this
account was created.
B.-->Creating the Subclasses
Create two subclasses for checking and saving accounts named as CheckingAccount and
SavingsAccount.
A checking account has an overdraft limit which is double type variable.
A savings account has issued with a credit card automatically. It holds the 16-digit card
number an expiry date (Calendar type object). SavingsAccount class must have a method
getCreditBalance that returns a credit balance which is three times of the current balance in
the account.
