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.$$

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.

$$Problem Description

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.

$$

$7.$ 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!$]$
