Assignment 4- Implementing a Banking Application Due: See course shell for due date and time
Check with you professor to see if you are permitted to work as a group. The application is by far
the most complex system that you have attempted so far. It consists of eleven classes, two
structs, one interface and two enums coupled in varying degrees of tightness. The Bank class is
the main driver of the application. It has a collection of Accounts and Person that is initialize
appropriately in the static constructor. You will implement the entire system in Visual Studio. A
short description of each type with their members is given below. You are advised to implement
each type in the order that they are described. No method should have a Console.WriteLine()
unless you are explicitly told to output something on the console. Each type must be in separate
files
Assignment 4, Winter 2022 Uses - Inheritance, Interfaces, Exceptions, EventHandlers,
Collections Operator overloading, hiding, and replacing members, Serialization, Generics, Linq
ExceptionType enum You will implement this enum in Visual Studio. There are seven members:
The members are self-explanatory. AccountType enum You will implement this enum in Visual
Studio. There are three members: begin{tabular}{|l|} hline AccountTypeenum hline
Constants hline Checking, Saving, Visa end{tabular} The members are self-explanatory.
Utils class [The implementation for this class is given in the appendix. Create a class called Utls
and copy and past the statements into the appropriate part of the file] You will implement the
Utils class in Visual Studio. This class is comprised of three fields and provides two static
properties. It simulates the passage of time. Each time the Time property is accessed, it increases
the internal field by a random amount. It is used to time stamped all banking events. A short
description of each class member is given below: Properties: There are three properties. 1. _time
- this private class variable is of type DayTime that store the time of this object. It is initialized
(with argument 1_048_000_000) at declaration. It is mutated (changed) whenever either of the
properties is accessed. 2. random - this private class variable is of type Random storing the time
of this object. It is initialized (with argument 1_048_000_000) at declaration. It is mutated
(changed) whenever either of the properties is accessed. 3. ACCOUNT_TYPE - this private class
variable is of type Dictionary. It serves as a lookup table to match an account type with a
particular prefix. It is initialized (code is given in the appendix) at declaration. Properties: There
are two properties, both of which are computed.

1. Time - this public class variable is of type DayTime. It adds a random value to the internal
field_time and then returns it. 2. Now - this public class variable is of type DayTime. It adds zero
to the internal field_time and then returns it. Methods: There are no explicitly defined methods.
You do not have to code this class. Just copy the code statements from the appendix of this
document.
ITransaction interface You will implement the ITransaction Interface in Visual Studio. The three
Account sub classes implement this interface. A short description of each class member is given
below: Properties: There are no properties. Methods: 1. void Withdraw(double amount, Person
person). 2. void Deposit(double amount, Person person).
AccountException class You will implement the AccountException Class in Visual Studio. This
inherits from the Exception Class to provide a custom exception object for this application. It
consists of a single a constructor: Fields: There are no fields Properties: There are no properties
Constructor: 1. public AccountException(ExceptionType reason )- this public constructor
invokes the base constructor with an appropriate argument. The base constructer argument is
obtain by calling the ToString() of the argument. [You are sending the argument of the child
constructor to the parent constructor.] Methods: There are no methods.
LoginEventArgs class You will implement the LoginEventArgs Class in Visual Studio. This
inherits from the EventArgs Class to provide a custom object for this application. It consists of
two properties and a single a constructor: Fields: There are no fields Properties: There are two
public properties, with no accompanying setters. Constructors: 1. public LoginEventArgs(string
name, bool success) - this public constructor takes a string and a bool argument and does the
following: a. Invokes the base constructor b. Assigns the arguments to the appropriate properties.
Methods: There are no explicitly defined methods.

TransactionEventArgs class You will implement the TransactionEventArgs Class in Visual
Studio. This inherits from the LoginEventArgs Class to provide a custom object for this
application. It consists of a single property and a single a constructor: Fields: There are no fields
Properties: There is one explicitly defined public property, with no accompanying setters.
Constructors: 1. public TransactionEventArgs(string name, double amount, bool success) - this
public constructor takes a string, a double and a bool argument and does the following: a.
Invokes the base constructor with the appropriate arguments. b. Assigns the middle argument to
the appropriate property. Methods: There are no explicitly defined methods.
Transaction struct You will implement the Transaction struct in Visual Studio. The only purpose
of this stuct is to capture the data values for each transaction. A short description of the struct
members is given below: Properties: There are no fields. Properties: All the properties are public
with the setter absent 1. AccountNumber - this property is a string representing the account
number associated with this transaction. The getter is public, and the setter is absent. 2. Amount -
this property is a double representing the account of this transaction. The getter is public, and the
setter is absent. 3. Originator - this property is a Person representing the person initiating this
transaction. The getter is public, and the setter is absent. 4. Time - this property is a DayTime
type representing the time associated with this transaction. The getter is public, and the setter is
absent.
Constructors: 1. public Transaction ( string accountNumber, double amount, Person person) -
This public constructor takes three arguments. It assigns the arguments to the appropriate
properties. It also sets the Time property to the Time property of the Utils class. Methods: 1.
public override string ToString( ) -This method overrides the same method of the Object class. It
does not take any parameter and it returns a string representing the account number, name of the
person, the amount, and the time that this transition was completed. [See the output for clues for
this method.] You must include the word Deposit or Withdraw in the output.
DayTime struct You will implement the DayTime struct in Visual Studio. The only purpose of
this stuct is to capture the time of an event. The logic of this class depends on the following: - 1

hour =60 minutes - 1 day =24 hours =2460=1_440 minutes - 1 month =30 days
=301_440=43_200 minutes - 1 year =12 months =1243_200=518_400 minutes - Time starts on
the zero minute of the zero hour of the first day of the first month of the zero year. i.e. 0 minute
will be 0000-01-01 00:00 A short description of the struct members is given below: Properties:
There is a single private field. 1. minutes - this private field is a long representing the minute
value of this struct. [The time on a computer system is a simple counter. The long counter
represents the number of ticks (milliseconds) since 1970 January 1] Properties: There are no
properties.
Constructors: 1. public Day ( long minutes ) - This public constructor takes a single long
argument and assigns it to the appropriate field. Methods: 1. public static DayTime operator + (
DayTime lhs, int minutes ) - This method overload the addition operator. Returns a new struct
with the original minutes that is increased by the second argument. This is used in the Util class
to get the current time (Utils. Now) and incremented time (Utils. Time). 2. public override string
ToString( ) - This method overrides the same method of the Object class. It calculates the year,
month, day, hour, and remaining minutes from the private minutes field. [See the output for clues
for this method.]
Logger class You will implement the Logger Class in Visual Studio. This is a static class with
some housekeeping duties. It handles all login attempts and transaction occurrences. A short
description of each class member is given below: Fields: There are two fields: 1. loginEvents -
this private static List field represents login attempts to the bank. This is initialized to an empty
collection at declaration. 2. transactionEvents - this private static Liststring>field represents login
attempts to the bank. This is initialized to an empty collection at declaration. Properties: There
are no properties. Constructors: There are no properties.

Person class You will implement the Person Class in Visual Studio. A person object may be
associated with multiple accounts. A person initiates activities (deposits or withdrawal) against
an account that is captured in a transaction object. A short description of each class member is
given below: Fields: There are two fields: 3. Password - this private string field represents the
password of this person. (N.B. Password are not normally stored as text but as a hash value. A
hashing function operates on the password and the resulting hash value is stored. When a user
supplies a password, it is passed through the same hashing function and the result is compared to
the stored value.) 4. OnLogin - this public event field represents the EventHandler that will store
the method to be invoked. Properties: All the properties are auto-implemented.
1. SIN - this string property represents the sin number of this person. The getter is public, and
setter is absent. 2. Name - this property is a string representing the name of this person. This
getter is public, and setter is absent. 3. IsAuthenticated - this property is a bool representing if
this person is logged in with the correct password. This is modified in the Login() and the Logout
() methods. This getter is public, and setter is absent. Constructors: 1. public Person(string name,
string sin)-This public constructor takes two parameters: a string representing the name of the
person and another string representing the SIN of this person. It does the following: a. The
method assigns the arguments to the appropriate fields. b. It also sets the password field to the
first three letters of the SIN. [use the Substring(start_position, length) method of the string class]
Methods: 6. public void Login(string password) - This method takes a string parameter
representing a password and does the following: a. If the argument DOES NOT match the
password field, it does the following: - Sets the IsAuthenticated property to false - Invokes the

EventHandler OnLogin with the following arguments: The current object reference (use this)
The second argument is of type LoginEventArgs. This will have arguments - the name of the
current object - and the success on the operation (use false in this case). - Creates an
AccountException object using argument AccountEnum.PASSWORD_INCORRECT - Throws
the above exception b. If the argument matches the password, it does the following: - Sets the
IsAuthenticated property is set to true - Invokes the EventHandler OnLogin with the following
arguments:
This method sets the IsAuthenticated property to false This method does not display anything 8.

two fields are readonly, persons representing the user who have access and transactions?
constructor to an empty collection. 2. transactions - this readonly puble field is a list of
transaction representing the deposits, withdrawal, payments and purchases of this account. This
initialized at in the constructor to an empty collection. 3. LAST_NUMBER - this private field is
a class variable of type int. It represents the last account number that was used to generate the
unique account number. It is initialized at declaration to 100,000 and is modify in the

amount ever drops to. This is modified in the Deposit() method. This is an autoimplemented
property the getter is public and the setter is protected 3. Number - this property is a string
representing the account number of this account. The getter is public and the setter is absent.
Events: 1. OnTransaction - this event is a double representing the amount in this account. This is

modified in the Deposit() method and in the PrepareMonthlyReport () method of the derived
classes. This is an auto-implemented property the getter is public and the setter is protected
Methods: 1. public Account( string type, double balance) - This is the public constructor. It takes
two parameters: a three-letter string representing the type of the account ("VS-", "SV-" and "CK-
" for visa, saving and checking account respectively) and a double representing the starting
balance. The method does the following: a. Sets the Number property to the concatenation
(joining) of the first argument and the class variable LastNumber b. Increments the class variable
LastNumber c. Assigns the second argument to the property Balance d. Assigns the second
argument to the property LowestBalance e. Initializes the field transactions to an empty list of
Transactions. f. Initializes the field users to an empty list of Persons. This constructor is called in
the constructors on the three derived classes 2. public void Deposit( double amount, Person
person) - This public method take a double parameter representing the amount to change balance
by and a person

count class. This method does not display anything, nor does it return a value. 3. public void
Adduser (Person person) - This public method takes a person object as a parameter. It adds the
argument to holders (the list of persons). This method does not return a value, nor does it display
anything on the screen. 4. public bool IsUser (string name) -This public method that takes a
string parameter because it is possible that multiple representing the name of the user and
returns true if users will have the same name the argument matches the name of a person in
holders (the list of persons) and false otherwise. You cannot use the Contains method of the list
class because the list is a list of persons and not a list of strings. You willhave to use a loep to
checkeach person in the eollection. Use linq to implement this method. This method does not
display anything on screen. 5. public abstract void PrepareMonthlyReport( )-This abstract public
method does not take any parameter nor does it return a value. Research how to declare an
abstract method. This method is implemented in the classes derived from Accounts. 6. public

double balance =0, bool hasoverdraft = false ) - This public constructor takes a parameter of type
double representing the
starting balance of the account and a bool indicating if this account has over draft permission.
The constructor does the following: a. It invokes the base constructor with the string " CK" and
the appropriate argument. [It uses the dictionary ACCOUNT_TYPE and the enum AccountType
to obtain the two letter prefix for this account type] b. Assigns the hasoverdraft argument to the
appropriate field. 2. public new void Deposit( double amount, Person person) -this public method
takes two arguments: a double representing the amount to be deposited and This definition hides
the corresponding a person object representing the person do member in the parent class because

OnTransactionoccur () method of the base class with the appropriate arguments. Read the above
Deposit() method for more explanation ii. Throws the appropriate AccountException object b. If
this person in not logged in, it does the following: i. Calls the OnTransactionoccur () method of
the base class with the appropriate arguments. ii. Throws the appropriate AccountException
object. c. If the withdrawal amount is greater than the balance and there is no overdraft facility, it
does the following: i. Calls the OnTransactionoccur () method of the base class with the
appropriate arguments. ii. Throws the appropriate AccountException object. d. Otherwise, it does
the following: i. Calls the OnTransactionoccur () method of the base class with the appropriate
arguments. ii. calls the Deposit() method of the base class with the appropriate arguments (you
will send negative of the amount)
4. public override void PrepareMonthlyReport ( ) -this public method override the method of the
base class with the same name. The method does the following: a. Calculate the service charge
by multiplying the number of transactions by the COST_PER_TRANSACTION (how can you
find out the number of transactions?). b. Calculate the interest by multiplying the LowestBalance
by the INTEREST_RATE and then dividing by 12 . c. Update the Balance by adding the interest
and subtracting the service charge. d. Re-initializes the collection transactions (use the Clear ()
method of the list class) This method does not take any parameter, In a real-world application,
the transaction objects would be archived before clearing.
