First, create a class called Person that implements the Comparable interface. Person will contain
a member variable to hold a name, a constructor that sets up the name, and three methods
(getName, compareTo, toString). getName returns the member variable, compareTo works as
defined by the Comparable interface, and toString returns the name neatly formatted. Second,
you\'ll compare Persons by their names. Include a main method in Person that asks the user to
input ten names and generates ten Person objects. A blank name should not be used to create an
object. Using the compareTo method, determine first and last person among them and print
them. Do not simply sort the Person data.
