8.19 Project
In this project, you are going to create simple bank software. You program will contain
the
Test
class, which contains the main method, and the
Customer
,
BankAccount
,and
Employee
classes, the abstract
Person
class, and the
Transaction
class. The
Customer
and
Employee
classes will both inherit from the
Person
class.
The
Person
class will be abstract and will contain the name, address, and telephone num-
ber of the person. Each object of the
Customer
class will store, in addition, an
ArrayList
of
the bank accounts for that person. Each object of the
Employee
class will store, in addition,
the salary of the employee. Each object of the
BankAccount
class will have a variable cor-
responding to the account number (of type integer) and an
ArrayList
of the transactions
for that account. Each object of type
Transaction
will contain the date of the transaction
(of type
Date
), the type of transaction (deposit or withdraw), the employee who performed
the transaction, the bank account on which the transaction was performed, and the dollar
amount of the transaction (to be stored in a double). Note that the current day and time
can be saved in a variable of type
Date
as follows:
Date d = new Date()
.Notethatall
instance variables should be declared
private
.
As you have probably guessed by now, you will need to create an
ArrayList
of
People
in the
Test
class. Your main method should print a menu that allows the user to insert a
new employee or a customer, create a new account for a person, or withdraw/deposit money
from/to a bank account. Operations, such as changing the address and phone number of
a person or the salary of an employee should also be supported. Your program should not
allow negative balances for bank accounts and should print an appropriate message, for
example, “Insu
cient funds to perform transaction” when a withdraw transaction tries to
withdraw too much money. For simplicity, you can assume that people and bank accounts
are never deleted. Use an automatically generated ID for people, transactions, and bank
accounts. The ID can be generated from a static variable that is initially set to 0.
