1. Write a program namedCreateCustomerFile.java that allows you to create a file of customers (Customers.txt) for a company. The first part of the program should create an empty file suitable for writing a three-digit ID number, six-character last name, and five-digit zip code for each customer. The second half of the program accepts user input to populate the file. Accept user input until999 is input for the ID number.

For this exercise, assume that the user will correctly enter ID numbers and zip codes, but force each customer name to six characters, padding it with spaces or truncating it if it is too long or too short. Issue an error message, and do not save the records if the user tries to save a record with an ID number that already has been used.

   Write a program namedCreateItemFile.java that creates a file of items carried by the company. Include a three-digit item number andup to a 20-character description for each item. Issue an error message if the user tries to store an item number that already has been used. Accept user input until999 is input for the item number.

   
   


2. 
   

   Write an application namedCustomerItemOrder.java that takes customer orders. Allow a user to enter a customer number and item ordered. Display an error message if the customer number does not exist in the customer file or the item does not exist in the item file; otherwise, display all the customer information and item information. Accept user input until999 is input for the customer ID number. An example program execution is as follows:

   
   

Enter customer ID number or 999 to quit >> 1 Enter item number >> 7 Customer: 1 Name: Joe zip code: 88888 ordered Item #7 which is a Cake/Brownies Enter customer ID number or 999 to quit >> 8 Enter item number >> 2 Customer: 8 Name: Jill zip code: 11111 ordered Item #2 which is a Cookies Enter customer ID number or 999 to quit >> 999
