// CSE 142, Spring 2010, Marty Stepp
// This class defines a new type of objects called BankAccount.
// Each BankAccount object represents information about one user's bank account
// information, such as their name and balance of money.
// A BankAccount has methods to deposit and withdraw money; these methods make
// sure that the account's balance does not become negative.
// An account also counts the total number of transactions performed on it.

    private double transactionFee;

//         BankAccount marty = new BankAccount();
//         marty.name = "Marty Stepp";
//         marty.balance = 1000000.00;
//         marty.id = 12345;
