Question

THIS IS JAVA PROGRAMMING

Design a class named Account (that contains

1. A private String data field named id for the account (default 0).

2. A private double data field named balance for the account (default 0).

3. A private double data field named annualInterestRate that stores the current interest rate (default 0).

4. A private Date data field named dateCreated that stores the date when the account was created.

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

6. A constructor that creates an account with the specified id and initial balance.

7. The accessor and mutator methods for id, balance, and annualInterestRate.

8. The accessor method for dateCreated.

9. A method named getMonthlyInterestRate() that returns the monthly interest rate.

10. A method named withdraw that withdraws a specified amount from the account and returns a boolean based on sufficient funds.

11. A method named deposit that deposits a specified amount into the account, and returns a boolean

12. A method call toString() that returns a “nicely formatted” string similar to the following:

ID: 1234567

Balance: $53,823.27

InterestRate: 0.036

Date Account Created: 10/23/2018

Draw the UML diagram for the class. Implement the class (write the Java code as specified by the UML diagram). Use the Lab7 test program (attached to dropbox) that creates an Account object with an account ID of 5544, a balance of $45,000.00 and an annual interest rate of 3.6%. Use the withdraw method to withdraw $3,700.00, use the deposit method to deposit $2,200.00 and print the balance, the monthly interest, and the date this account was created. Keep in mind that while this tester has hard-coded values, the Account class should be usable by a full-blown application. As such, refrain from having Account.java print messages or accepting input from the keyboard.
