A Flexible Account Class

File Account.java contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a String representation. Note that the constructor for this class creates a random account number. Save this class to your directory and study it to see how it works. Then modify it as follows:

1. Overload the constructor as follows:

• public Account (double initBal, String owner, long number) - initializes the balance, owner, and account number as specified
• public Account (double initBal, String owner) - initializes the balance and owner as specified; randomly generates the account number.
• public Account (String owner) - initializes the owner as specified; sets the initial balance to 0 and randomly generates the account number.

2. Overload the withdraw method with one that also takes a fee and deducts that fee from the account.

File TestAccount.java contains a simple program that exercises these methods. Save it to your directory, study it to see what it does, and use it to test your modified Account class.
