Write a program that allows you to create a file of customers for a company. The first past of the program should create an empty file suitable for writing a three-digit ID number, six-character last name, and a five-digit zip code for each customer (fixed-length, text file). The second half of the program accept user input to populate the file. For this exercise, assume that the user will correctly enter the ID numbers and zip codes, but force the customer name to six characters if it is either too long or too short padding with spaces or truncating as needed. Issue an error message and do not save the record if the user tries to enter an ID number which has already been used. Save the program as CreateCustomerFile. java
