Create an Inheritance hierarchy that a bank may use to represent customer's bank accounts (Checking and Savings), this includes a GUI user interface that allows user to login, and deposit or withdraw, and application to display the transaction and final balance.
All the bank customers can: - Create a new account - Deposit (Credit) money into their account and/or withdraw (debit) money from their account. - Application should expect user to login to their account using login/password Create necessary classes and Java application to use and test these classes. Savings Accounts - earn interest on the money in the account. Checking accounts - charges a fixed fee for each transaction the customer makes. Create base class Account, with derived classes SavingsAccount and CheckingAccount that inherit from Account Account: contains - initialBalance Constructors, getter/setters validation for initialBalance, credit() - make input is correct and positive and credit the account debit() - make sure there is enough money, otherwise it should left unchanged Account:SavingsAccount Inherit from Account additional property called interestRate (percentage assigned to account) SavingsAccount Constructor should receive initialBalance, value for interestRate method calculateInterest() that returns the amount of interest CheckingAccount Inherit from Account additional instance variable for fee charged per transaction Constructor should receive the initialBalance and fee amount Should redefine debit () and credit () to take under consideration the fee charged
Now create and application that creates objects of each class to test each method. Add interest to the savingsAccount object by first invoking its caculateInterest () method, then pass the returned interest amount to the object's credit () method. Develop a polymorphic banking application using the Account hierarchy. Create an array of Account references to SavingsAccount and CheckingAccount objects. For each account in the array, allow the user to specify an amount of money to withdraw from the account using method debit() and an amount to deposit into the account using the method deposit(). As you process each Account, determine its type. If an account is a SavingsAccount, calculate the amount of interest owed to the Account using method calculateInterest(), then add the interest to the account balance using method credit().
After processing an Account, print the updated balance obtained by using the getBalance() from the base class. Interactively ask the user for information for each account and then print the result for each account. Create Custom Exception NegativeBalanceException for the cases when user try to withdraw amount beyond available balance.
In order to get the complete point for the assignment, make sure you follow the coding guidelines provided. Submit a copy of the following items to Blackboard: A copy of the source code Captured output for each program (use < prt sc> to capture the output) UML Diagram for assignment, make sure to use software to do the flow charts (use correct symbols) Make sure your code if well commented Make sure your code is indented correctly Make sure each listing has a prologue at the beginning (Description of your Application) Refer to the Guidelines and coding standards provided in the external links No late assignment will be accepted unless it has been arranged previously This applies to all the homework you turn in Turn in a zipped file that contains all the necessary files
-This is in Java
-Need a GUI component too
