Problem Description For this problem, you will design an inheritance hierarchy

based on a rough description of the problem to solve.

Grading will be based on your ability to demonstrate

appropriate use of classes, subclasses and interfaces to

formulate a viable solution. There is no single "correct"

answer!

This is a design exercise. YOU ARE NOT CODING! Your job is to

read details from the following description of part of an

application, and design an inheritance hierarchy as a UML Class

Diagram showing your design for the relevant classes and

interfaces.

As was the case in our HW$5-2$ assignment, you'll need to design

with at least two Interfaces and at least one superclass $[$i$.$e$.,$

related to the problem described$]$ and at least two subclasses.

$[$Note: you will probably need more than the minimums to model

the problem!$]$

For the purpose of this exercise, you should omit fields from your

diagram, and focus on showing methods relevant to the

specification and interface design.

Each class or interface should show some relevant methods and

access level $(-$ for private, # for protected, $+$ for public$).$ Methods

should show name, parameters, and return type. Underline

abstract methods in your design.

Abstract classes, if any: names should be underlined. Create an original design for a hierarchy of Account using good

interface and abstract class design as appropriate.

For this test, design an inheritance hierarchy to represent the kind of

information described above. $[$You can enhance a bit, based on your

knowledge of banking, but you aren't being graded on your financial

expertise!$]$

SKETCH your hierarchy and take a pdf$,$ png or jpg to upload,

OR use Word or a diagramming tool and upload your

document

Must use arrows correctly to indicate relationships

$[$subclass$,$ implements an interface, etc.$]$

In your diagram, clearly show each class and

interface.

$[$correct use of arrows should do

this$],$

In each class or interface, identify abstract and$/$or

concrete methods and show method headers $[$no

code needed$].$

$[$could be in a "caption" of text for

each object in a separate section$],$

You can underline any abstract

methods if you can't use italic

type.

$[$I should be able to understand your design from the diagram and

notations!$]$

Upload $($attach$)$ your solution as a pdf$,$ png$,$ jpg or Word doc. $($Be

sure to do this before time limit for this problem is reached!$)$

The Big Bank offers a number of kinds of accounts for their customers. Your

challenge will be to design a hierarchy of classes and some interfaces to support

the desired functionality.

Each Customer may have many different Accounts. For this problem, you may

assume that an instance of class Customer will encapsulate information about

each customer, including name, address, and social security number. You may

represent an instance of this class as$,$ e$.$g$.,$ Customer $c$ in any account class, but

you should not try to diagram the Customer class in your hierarchy.

Every Account should have a unique accountNumber.

It should be possible to "process" a group of Accounts in a polymorphic

collection such as an ArrayList, and traverse using a single loop, such as a for$-$

each loop. $[$Note: you are not tasked with writing code to do this!!$]$

Here are some types of Accounts and the features they support.

A Standard Checking account allows for withdraw$()$ and deposit$()$ and has a

maintenanceFee if the balance falls below some published minimumBalance in

any month. There is no fee for writing checks. No interest is given for funds in

this account.

A Student Checking account supports withdraw$()$ and deposit$()$ and has no

monthly maintenance fee, and no minimum balance There is a small checkFee

for each check written in any month beyond the published number of

CheckLimit. No interest is given for funds in this account.

A Senior Checking account supports withdraw$()$ and deposit$()$ and has a

maintenance fee if the balance falls below some published minimum balance

in any month. There is no fee for writing checks. Funds in this account are

credited with interest at a published interestRate via an applyInterest$()$

A Standard Savings account supports deposit$()$ and up to some withdrawLimit

of withdraw$()$s per month. There is no fee for this account. Funds in this

account are credited with interest at a published interestRate via an

applyInterest$()$

A HolidaySavingsClub is a special account that has a maturityValue and

allows customers to make a set numberOfDeposits $($usually $50)$ of regular

deposits for a fixed depositAmount before a pre$-$determined maturityDate. If

the Customer makes deposits as required, they can close the account after

the maturityDate and receive the full maturityValue. For example, if a

customer sets up a $$10$ per week depositAmount and makes all payments,

they might receive a maturityValue payout of $$550$ for $$500$ worth of

deposits.
