Guidelines & Programming Tasks

In this assignment you will apply basic principles of object? oriented programming to create a basic banking application.  This application receives withdrawals, deposits, and an interest rate; a balance is computed that includes interest earned.  Below is the equation needed to compute the balance.

Balance = (Deposit – Withdrawals) * (1 + monthly interest rate)

Create a GUI that contains text boxes needed for a user to enter the total deposits, total withdrawals, and the interest rate.  Your GUI will also need a read?only text box for displaying the balance Figure 1 shows the expected layout of your GUI.  Be certain to appropriately label your control objects. The text boxes for Deposits, Withdrawals, and Annual Interest Rate will be used to obtain values from the user.  The text box Balance is to be a read only field.

You are to create a class named Finance that is to contain the properties: Deposit, Withdrawal, InterestRate, and Balance.  The Balance property should be Read Only.  These properties should be of the string data type. Within this class you are to create a method named computeBalance that calculates the balance using the formula above.  Allow users to enter an annual interest rate, however when computing the monthly balance remember that interest is earned on a monthly, and not a yearly, basis.

Your instance of the Finance class is to be named bank.   

Document your design with pseudocode, embed your pseudocode as a comment in your code, place the pseudocode at the beginning of your program.
