Exercise 4-3-2

This exercise will be handed in by the due date listed on the term outline page.

The HTS Bank has been opened with 6 depositors.
You will create a program that will use arrays and methods to answer questions about the depositors. (e.g. One question is 'what is the total of money deposited with the bank'.)

To get a SAMPLE program that you will need to add to, look HERE.

In the main method, create two arrays, one with the names of the bank depositors and the other with the depositors' current bank balances. Give at least one depositor a balance of zero, at least one depositor a negative balance (overdrawn), and the others can have positive balances.
For example:

Depositor	Balance of account
Patrick	75.23
Rachel	83.50
Aaron	73.23
Margaret	-79.01
Mary	0
Thomas	-10.34

Create a keyboard object by adding these lines OUTSIDE of the main method:

private static InputStreamReader input = new InputStreamReader(System.in);
private static BufferedReader keyboard = new BufferedReader(input);

(We do this so that each of the methods can use these items instead of creating a separate keyboard connection for each method.)

In the main method, the do...while loop will continue until the use enters the letter 'Q' to stop.

In do loop, add the code to display the menu of options. It will give the teller (user) to use any of the following methods in the exercise. The user will enter a letter:

HTS Bank Menu
O     Overdrawn accounts
P      Normal accounts
T      Total of account balances
I       Add interest
Q      Quit
Enter choice-->_

ALSO, add the code to get the user's choice from the keyboard entry. Add a line of code just after the menu to do this.

Create a method that will find and display the names and balances of all overdrawn depositors. This method is a void method.

Create a method that will find and display the names and balances of all customers with positive balances. This method is a void method.

Create a method that will find the total of all the account balances. This method is a double method.

Create a method that will take all of the positive balances and add interest of 0.5% to the account balance for this month's interest. Total all of the interest paid and display this at the end. This method is a void method.

	Interest of $1.16 added to accounts with a positive balance
	Note that the total after adding interest has increased by $1.16

Update your code to use the keyboard objects by adding this method for keyboard entry:

public static String enterInS (String prompt) throws Exception {
// prompt message received from calling method
// allows user to enter in a string from the keyboard

System.out.print (prompt);
return keyboard.readLine();

} // enterInS

for example:

prompt = "Enter choice-->";
choice = enterInS( prompt ); // get menu choice
