folder you should create a Java interface with 2 method declarations, and a class that implements that interface. You can name the interface and implementation whatever you want, but they should make sense from an interface/implementation perspective. The interface and class must compile and be well commented on to receive credit and you should explain what an interface is/does/provides programmatically in your comments as well as why you chose to name your interface and class the way you did. Remember, the naming must make sense from an interface/implementation perspective.
