Demonstrate using code examples how you would use a List to

represent the customers registered with an online store. You should sort

the List in such a way that the order of customers is based on the

lexicographic order $($natural ordering of String$)$ of their surname

followed by their first name.

Note: you can represent a customer by their surname, first name, and

email address only.

Illustrate the code for adding customers called Serena Williams and

Venus Williams to the List before sorting it$.$

What would the program output be if you print the List to the console?

Your code should include a toString$()$ method in the Customer

class that returns a formatted string of the form:

Name: Williams, Serena
