Part One
Extend your InterestBank class to read and write account information to a file. You should extend your (or my) InterestBank class with a new class called FileBank or something similar. You should not have to modify your InterestBank or your BankAccount or your InterestBearingBankAccount classes!
Add a method which writes out to a file all the information about the accounts in the Bank.
Add a method which reads in account information from a file and creates those accounts in the Bank.
Part Two
Test your code by creating a FileBank in main(), reading account information in from a file. Have main create a few more accounts, and then write them out to a file.
What to turn in
Print out and turn in the code and any test runs of your results from part two. Also turn in a print out of the file written by your Bank.
Turn these in at the beginning of class on 18 April, 2007.
