Part One • A hotel salesperson enters sales in a text file. Each line contains the following, separated by semicolons: o The name of the client, o the service sold (such as Dinner, Conference, Lodging, and so on), o the amount of the sale o and the date of that event. • Prompt the user for data to write the file. Part Two • Write a program that reads the text file as described above, and that writes a separate file for each service category, containing the entries for that category. Name the output files Dinner. txt, Conference. txt, and so on. • Enter the name of the output file from Part One as a command line argument. Both Parts • For all programs, catch and handle the Exceptions appropriately and validate the input data where needed. • Display an error if the sales file does not exist or the format is incorrect. • Also, create your own exception to handle "unknown transaction" exceptions.
