Question
Chapter 12, Problem 6PE
Program Plan Intro
Modified implementation of the classes in the ATM simulation
Program plan:
- In the file “BankAccount.java”, create a class “BankAccount”,
- Declare the variable.
- Define the constructor to create a bank account with “0” balance.
- Define the parameterized constructor to create a bank account with a given balance.
- Define the method “deposit()” to credit amount into the bank account.
- Define the method “withdraw()” to debit amount from the bank account.
- Define the method “getBalance()” to get the current balance of the bank account.
- In the file “Customer.java”, create a class “Customer”,
- Define the constructor to construct a customer with a given number and PIN.
- Define the method “match()” to check if this customer matches a customer number and PIN.
- Define the method “getCheckingAccount()” to get the checking account of this customer .
- Define the method “getSavingsAccount()” to get the savings account of this customer.
- In the file “Bank.java”, import necessary packages, and create a class “Bank”,
- Declare the necessary array lists.
- Define the constructor to construct a bank with no customers and no accounts.
- Define the method “readCustomers()” to read the customer numbers and pins and initializes the bank accounts.
- Define the method “findCustomer()” to find a customer in the bank.
- In the file “ATM.java”, create a class “ATM”,
- Declare and initialize necessary variables.
- Define the constructor to construct an ATM for a given bank.
- Define the method “reset()” to reset the ATM to the initial state.
- Define the method “setCustomerNumber()” to set the current customer number and sets state to PIN.
- Define the method “selectCustomer()” to find customer in bank. If found sets state to ACCOUNT, else to START.
- Define the method “selectAccount()” to set current account to checking or savings. Set state to TRANSACT.
- Define the method “withdraw()” to withdraw amount from current account.
- Define the method “deposit()” to deposit amount to current account.
- Define the method “getBalance()” to get the balance of the current account.
- Define the method “back()” to moves back to the previous state.
- Define the method “getState()” to get the current state of this ATM.
- In the file “ATMSimulator.java”, import necessary packages, and create a class “ATMSimulator”,
- Define the method “main()”,
- Execute “try” statement to handle exception if any,
- Crate an object for “Bank”.
- Call the method “readCustomers” to read the input file.
- Create “ATM” object.
- Catch and handle the exception if any.
- Create “Scanner” class.
- Execute the following or true,
- If it is START state, get the customer number.
- Otherwise, If it is PIN state, get the pin.
- Otherwise, if it is ACCOUNT state, get the type of account.
- Otherwise, if it is TRANSAC state, perform the type of transaction.
- Execute “try” statement to handle exception if any,
- Define the method “main()”,
