public class FruitItem$\{$

a$.$ Arrange the above classes into an appropriate inheritance hierarchy. Note: do

NOT add fields or methods to any of these classes.

b$.$ Add default constructor for each class, which prints "I am a YYYY$".$ For

example, the Tomato class should print "I am a tomato". In addition, the parent

information should be printed too.

c$.$ Implement a test class that instantiates a new instance for each class.
