We are simulating a customer database for a store

Crete a text file that represents information about several customers of the store: Each customer will take 4 lines in the file

Username, First Name, Last Name on the first line

Last 6 passwords on the second line

Names for the last 10 items purchased on the third line

Prices for the last 10 items purchased on the fourth line

Notes:

Usernames must be unique for each customer

Passwords must contain 8 characters (with 1 letter, 1 number, 1 symbol)

The passwords are in order from newest to oldest

All data is separated by commas in the file

Items are listed in order from newest to oldest

Your test file should have at least 3 customers in it for testing purposes

Writ a program that let's a store manager enter a username and then give them the choice to do the following:

Get the First Name

Get the Last Name

Get the Current Password

Change the First Name

Change the Last Name

Change the Password (Can't be one of the last 6 passwords used)

Add a new item to purchase list (Remember it can only hold 10 values)

View all items / prices purchased

View all items / prices purchased from (highest priced to lowest priced) or (lowest priced to highest price)

Get the highest priced item

Get the lowest priced item

Get the price of any item in the list

Calculate the average cost of the items in the list

Calculate the median price of the items in the list

To help you accomplish these tasks you should crete a Customer Object Class and use it to write the program above

The class should have the following fields:

String: Username

String: First Name

String: Last Name

String[]: Passwords

String[]: Item Names:

Double: Item Prices

It should have a constructor that fills in all of the fields

It should have methods that can accomplish all of the tasks the main program needs
