In this assignment we will design an interface to enforce behavior in the AppleLogger class. We will also

modify the equals method in the AppleShipment class so that it is a true override of the equals method

inherited from the Object class.

$$ Declare an $"$ AppleShipmentManager" interface in the AppleLogger source file which enforces the

behavior of the following methods:

public void addShipment$($AppleShipment shipment$)$

public void showShipments$()$

public ArrayList find$($String typeSubstr$)$

$$ Modify the AppleLogger class so that it implements this interface.

$$ Modify the "equals" method in the AppleShipment class so that it accepts an Object parameter type

instead of an AppleShipment. Use the instanceof operator in the method to determine if the

parameter is an AppleShipment reference. If it is$,$ assign it to a local AppleShipment variable with a

cast operation and then continue the check for equality as before $($return false if the parameter is

not an AppleShipment reference$).$

$$ Add an @Override annotation to the equals method.
