/* Work to do: 1) add toString method to BankAccount and SavingsAccount classes
2) Override the withdraw() in SavingsAccount so that it will not withdraw more money than is
currently in the account.
3) Provide constructors for SavingsAccount
4) Add this feature to SavingsAccount: If you withdraw more than 3 times you are charged $10 fee
and the fee is immediately withdrawn from your account. once a fee is deducted you get another 3 free withdrawals.
5) Implement the Comparable Interface for SavingsAccount based on balance.
Once you finish adding/modifying the code make sure it compiles and run.
Submit your modified InheritanceTester. java file to the assignment folder
Warning: Notice that there are 3 classes in one file, and only one of them is public,
and this public class name should be the filename. Be careful about the { } braces.
