Problem: Checking Account
+-----------------------+
This project involves a simple checking account problem that requires the
following specific tasks.
1. Customer deposits
2. Customer withdraw
3. Applying service fee
4. Getting current balance
5. ... Add other functionality as needed
A check account fields consists of these
1. First Name, Last Name
2. Account Number
3. Balance, which reflects the current amount at the account
4. Amount
5. Transaction, which could be deposit, withdraw, or charge
6. Date
7. ...
Requirements
+------------------------+
1. Use plain file as database to maintain the customer data. Each transaction
must be recorded into this file.
2. Print current balance after each five transaction.
3. Reading directly from input stream into Java data type is error prone.
For instance, if the data consists of a set of digits mixed with alphabet
while it was expected to be a pure number, the reading operation most
certainly will fail. One possible solution to this problem is writing a
filter which helps verify that the incoming data is the correct data type.
So, add filtering feature for your program.
4. You must use method for each task outlined above.
2. Use the data file provided to test your program. The exact copy of the
data is given below.
