( The Account class ) Design a class named Account that contains: A private int data field named id for the account. A private float

(The Account class) Design a class named Account that contains:

A private int data field named id for the account.

A private float data field named balance for the account.

A private float data field named annualInterestRate that stores the current interest rate.

A constructor that creates an account with the specified id (default 0), initial balance (default 100), and annual interest rate (default 0).

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

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

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.

Draw the UML diagram for the class, and then implement the class. (Hint: The method getMonthlyInterest() is to return the monthly interest amount, not the interest rate. Use this formula to calculate the monthly interest: balance * monthlyInterestRate . monthlyInterestRate is annualInterestRate / 12 . Note that annualInterestRate is a percent (like 4.5%). You need to divide it by 100 .)

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 id, balance, monthly interest rate, and monthly interest.

From 7.3 which is already solved on cheg.

Programming Exercise 7.3. Call your files assn11-task2.py and account.py.

Read the exercise in the book first, so these instructions make sense. Instead of writing the test program as instructed in the book, write a program that obtains user input to use the Account class. The program should ask for the starting values for id, balance, and interest rate. The program then should present a menu where a user can access/modify their account. After each selection an appropriate message should be displayed. The menu should then be displayed again (Unless Exit is selected)

Example Menu:

(1): Display ID

(2): Display Balance

(3): Display Annual Interest Rate

(4): Display Monthly Interest Rate

(5): Display Monthly Interest

(6): Withdraw Money

(7): Deposit Money

(8): Exit

Make sure to read the rubric to see the additional requirements. Note: you do not need to write the program to test as described in the book. You will be writing a different program to use the class.
