Activity: Savings Account
You are a bank manager and you are
helping a new bank teller understand the kind of accounts the bank offers. If a
customer comes in asking to open a new savings account, the teller needs to ask
what kind of account–passbook savings or certificate of deposit–the customer
would like to open. Remind the customer that all accounts with our bank are
insured by the FDIC. You should explain that all accounts earn some interest; a
savings account’s interest is compounded monthly. You should assign a unique
account number after accepting the customer’s initial deposit. If the customer
chooses to receive statements electronically, the system will send an e-mail
with a monthly statement; if the customer chooses not to, then a paper
statement will be sent by mail quarterly.
If savings account is a class, give
an example of each of the following as it relates to that savings account. Explain
your reasoning behind your example.

Individual Assignment:
Compare Total Compensation. You will compare the total
annual compensation of at least two sales persons. That means that it MUST
be able to compare two, three or more sales persons.
Calculate Extra Sales. It will calculate the additional
amount of sales that each salesperson must achieve to match or exceed the
higher of the two earners. NOTE that you are computing the extra sales
required to achieve the same compensation. Sales and compensation are
related but different.
Sales Person’s Name. The application should ask for the
name of each salesperson being compared. Note that in Java, an object

sales person’s annual sales, base salary, commission rate, etc.
The Java™ application should also meet these technical
requirements:
The application should have at least one class, in
addition to the application’s controlling class. THAT means TWO CLASSES
or more.
The source code must demonstrate the use of Array or
ArrayList.
There should be proper documentation in the source
code.
