Thread: NEED HELP ALL the way with this..

Problem Description

Write a program to process bank accounts. Create a super class named Account and two subclasses named Savings and Checking. In the superclass, use an int AccountNum and a double balance for data members. Also, create two methods to do deposit and to do withdraw. Create one abstract method calculateDailyInterest that calculates and returns the daily interest. The method also adds the daily interest to the balance. The savings account is getting 3% annual interest rate. The checking account is getting 2% annual interest rate for amount that over $500.

Sample Run:

Enter one of the following
1) Create a new Checking Account
2) Create a new Savings Account
3) Make a Deposit
4) Make a Withdraw
5) Display all accounts
6) Calculate Daily interest
7) Exit


1
A new Checking account with account number: 1
Enter the initial balance 1000
2
A new Savings account with account number: 2
Enter the initial balance 800
2
A new Savings account with account number: 3
Enter the initial balance 500
5
*********************************
Account 1 has balance 1000.00
Account 2 has balance 800.00
Account 3 has balance 500.00
*********************************
3
Which account to deposit? 1
Enter the amount of deposit: 50
5
*********************************
Account 1 has balance 1050.00
Account 2 has balance 800.00
Account 3 has balance 500.00
*********************************
4
Which account to withdraw? 2
Enter the amount of withdraw: 80
5
*********************************
Account 1 has balance 1050.00
Account 2 has balance 720.00


Problem Requirement
a) You must use a separate file for each class.
b) You must use a separate file for the Testing program.
c) Your program must produce the prompt and the output the same as given.
d) Your program should run correctly with the same inputs and outputs as given in the sample run.
e) The balances should be displayed with 2 decimal places.

I haven't tried anything...

thanks!! tomorrow afternoon

That might be a bit tight. Didn't you say it might take 2 days Junky

nah...don't say that...lol

No one is coding anything for you. Get to work. Come back when you have code and need help.

this is what I have so far...I just wrote the best I could...I get an error on my laptop and I haven't been able to view any files that I have done this semester..Im going to login and tell you what error I am getting

did that work?

I don't have java on this pc.. I have to get help to download it and instructions on how to view it. But is this better now...?
