The document describes a banking program that simulates basic banking operations. It includes classes like Account, SavingsAccount, CheckingAccount, Customer, Bank, and Transaction. Account has fields like customer, balance, account number, and transaction array. Customer has fields like name, address, age, etc. Bank has an account array to store accounts. The program allows adding accounts, making deposits, withdrawals, and processes transactions.

1. Write a banking program that simulates the operation of your
local bank. You should declare the following collection of
classes. Class Account Data fields; customer (type Customer),
balance, accountNumber, transactions array (type Customer),
Transaction []). Allocate an initial Transaction array of a
reasonable size (e.g., 20), and provide a reallocate method that
doubles the size of the Transaction on array when it becomes
full. Methods: getBalance, getCustomer, toString, setCustomer
Class SavingsAccount extends Account Methods: deposit,
withdraw, addInterest Class CheckingAccount extends Account
Methods: deposit, withdraw, addInterest Class Customer Data
fields: name, address, age, telephoneNumber, customerNumber
Methods: Accessors and modifiers for data fields plus the
additional abstract methods getSavingsInterest.
getCheckInterest, and getCheckCharge. Classes Senior, Adult,
Student, all these classes extend Customer Each has constant
data fields SAVINGS_INTEREST. CHECK_INTEREST,
CHECK_CHARGE, good! and OVERDRAFT_PENALTY that
define these values for customers of that type, and each class
implements the corresponding accessors. Class Bank Data field:
accounts array (type Account []). Allocate an array of a
reasonable size e.g., 100), and provide a reallocate method.
Methods: addAccount, makeDeposit, make Withdrawal,
getAccount Class Transaction Data fields: customerNumber,
transactionType. amount, date, and fees (a string describing
unusual fees) Methods: processTran You need to write all these
classes and an application class that interacts with the user. In
the application, you should first open several accounts and then
enter several
