Java program that reads in a file of products, JAVA Programming

Assignment Help:

Write a Java program called SalesInfoMiner that reads in a file of products, stored in text format (2 lines per entry). The program must then read in information about past sales transactions and output all the products to a new file, sorted by product description, along with their sales rank and the five other products with which they were most commonly purchased.

The program accepts four command line arguments and must not expect any user interaction from the keyboard. The first parameter to the program is the name of the product list to read in; the second parameter is the file containing information about past transactions. The third parameter is the name of the file to which the ordered product list will be written, and the fourth parameter is the name of the file to which any error or warning messages will be output.
