Write an application for a mail order company. The program uses a data entry screen in which the user types an item number and a quantity. Write each record to a file. Save your file as MailOrder.java. Compile and run the program until it works and the output looks nice, add the necessary documentation as described in Course Documents, and then attach your .java file to this assignment. Do not attach the .class file, attach only your source code. This assignment is due the last day of the academic week.
