Design a bank teller application that allows the teller to create/add accounts (checking or savings), deposit to accounts, withdraw from accounts, apply interest to savings accounts, update interest rate, process monthly fee on checking accounts, and display all information for an account. Store the accounts ArrayList of objects and use static methods where necessary. The BankAccount and CheckingAccount classes are created for you and can be found in Moodle. The SavingsAccount class has been started but you must complete the 6 tasks in the file before you can use savings account. CheckingAccount and SavingsAccount inherit from the BankAccount class. Be aware you may need to add a field to the BankAccount class in order to identify accounts.

Be sure to test the application with multiple input values and types of accounts. Test each task multiple times.

You may add other functionality you consider relevant but be sure to include what is listed above at a minimum.
