Textbook Question
Chapter 9, Problem 9.7PE
(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).
- A private double data field named annual InterestRate that stores the current interest rate (default 0). Assume that all accounts have the same interest rate.
- A private Date data field named dateCreated that stores the date when the account was created.
- A no-arg constructor that creates a default account.
- A constructor that creates an account with the specified id and initial balance.
- The accessor and mutator methods for id, balance, and annual InterestRate.
- The accessor method for dateCreated.
- 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 then implement the class. (Hint: The method getMonthlyInterest () is to return monthly interest, not the i nterest rate.
Monthly interest is balance * monthlyInterestRate. monthlyInterestRate is annual InterestRate /12. Note annual InterestRate is a percentage, for example 4.5%. You need to divide it by 100.)

In this assignment, you will use all of the graphics commands you have learned to create an animated scene. Your program should have a clear theme and tell a story. You may pick any school-appropriate theme that you like.
The program must include a minimum of:
5 circles
5 polygons
5 line commands
2 for loops
1 global variable
You may wish to use the standard code for simplegui graphics below:
import simplegui def draw_handler(canvas): frame = simplegui.create_frame('Testing', 600, 600) frame.set_canvas_background("Black") frame.set_draw_handler(draw_handler) frame.start()
Submit Your Code
After you write your code here in the programming environment, you will check it and submit it as usual. However, the grader will only perform basic checks against some requirements. If your code passes, you should submit your work, and your teacher will manually grade your submitted work using a rubric.
1. What is the difference between a relative cell reference and an absolute cell reference and give an example of when you would use each.
What is the goal of using a chart in excel, and how is a chart useful and what is the goal of using sparklines in excel, and how are sparklines useful?
