1. CustomerLottery (90)

Each year, Sleepy Hollow SuperStore holds a Manager for a Day lottery. A manager can participate by entering his/her name and ID number into a pool of candidates. The winner is selected randomly from all entries. Each customer is allowed one entry.

Customer class (10)

A Customer object holds a customers name as well as his/her ID number.

The name is a single word of type String.

The id is of type int.

The Customer class has the usual getter and setter methods. Further, Customer overrides the equals(Object o) method inherited from Object so that two students are equal if they have the same name and ID number. It also overrides toString().

StoreLottery class (60)

Implement a class StoreLottery, with the methods described below.

This class is instantiated with no parameters.

It has a an ArrayList of type Customer.

I suggest having a global Scanner for reading interactive input

void addCustomers

The addCustomers() method enters customers in the lottery and checks that there are no duplicate entries added to the list. To do this you should read in the customers from a file. You can read in the names from customerlist.txt in the Programs/Lesson 5/Homework tab, but your program should request the name of the file interactively.

Print out the names of any duplicates to the screen.

When all customers are read in,

Sort the list using the CustomerSortingComparator

Call printUnduplicatedList()

Call pickWinner() as described below.

void printUnduplicatedList()

Requests the name of an output file

Creates an Iterator prints out the unduplicated list to the output file using the Iterator

Then prints out the unduplicated list to the output file using an enhanced for

void pickWinner

The void pickWinner() uses the Random class to select one winner from among all customer entries (picked based on number of entries). It prints the name of the winner to the screen.

CustomerSortingComparator class (10)

Sorts the list of customers by name and if the names are the same sorts by ID

TestLottery class (10)

Includes a main method that creates a StoreLottery and then calls the addCustomers() method.
