(The Account class)    

 

Account

 

-id: int

-balance: double

-annualInterestRate : double

-dateCreated : Date

 

+Account( )

+Account(someId : int, someBalance : double)

+getId() : int

+setId(newId : int) : void

+getBalance() : double

+setBalance(newBalance : double) : void

+getAnnualInterestRate( ) : double

+getDateCreated( ) : Date

+getMonthlyInterestRate( ) : double

+getMonthlyInterest( ) : double

+withdraw(amt : double) : void

+deposit(amt : double) : void

 

 

    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).

■ A private double data field named annualInterestRate that stores the current interest rate (default 0). Assume all accounts have the same interest rate.  Make it static.

■ A private Date data field named dateCreated that stores the date when the account was created.  (private Date dateCreated)  You will need to do dateCreated = new Date( ) in your constructor to initialize the dateCreated property. 

■ A no-arg constructor that creates a default account.

■ A constructor that creates an account with the specified id and initial balance.  The property annualInterestRate will be set by the test program and not through the constructor.

■ 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.

■ A method named getMonthlyInterest() that returns the money earned in a month.

■ A method named withdraw that withdraws a specified amount from the account.

■ A method named deposit that deposits a specified amount to the account.

 

 (Hints: The method getMonthlyInterest() is to return monthly interest, not the interest rate- the amount earned in one month. Monthly interest is balance * monthlyInterestRate. monthlyInterestRate is annualInterestRate / 12. Note that annualInterestRate is a percentage, e.g.,like 4.5%. You need to divide it by 100.)

 

Write a test java 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 and again after the deposit and withdraw.
