Polymorphism Exercises

Discuss with someone else:
1. The benefits of using polymorphism
2. Three scenarios that could benefit from polymorphism
Write a simple Java program that has a polymorphic call. Use comments to label each of the essential ingredients for a polymorphic call.
In the AccountsDriver class from the Inheritance Exercises, add a (static) method named displayAccount() that takes a SimpleBankAccount reference. In that method, make a call to toString() on that reference parameter and display the results. Furthermore, in the main() method (in that same class, replace):
```
System.out.print( checking.toString() );
```
with
```
displayAccount( checking );
```
and
```
System.out.print( savings.toString() );
```
with
```
displayAccount( savings );
```
