Implement a JAVA application that keeps track of package deliveries to consumers. The
application consists of the following classes:
Item: Create a class called Item. The class has two member variables of
type String named name and description and provides getter and setter
methods for both.
Mail (abstract class): Implement an abstract class called Mail . The class has
a member variable of type String named address and a getter method for it.
Letter: Implement a class called Letter that inherits from Mail . The class
has one member variable of type String named contents.
Package: Implement a class called Package that inherits from Mail . The
class has one member variable of type Item[] named items and a getter
method for it.
DeliveryTruck: Implement a class called DeliveryTruck with a single
member variable of type Mail[] of length 10. Add the following method:
o void load(Mail mail): This method stores the given mail argument
at the next available spot in the member variable..
