Question

A company accepts user orders by part numbers interactively. Users might make the following errors as they enter data: • The part number is not numeric. • The quantity is not numeric. • The part number is too low (less than 0). • The part number is too high (more than 999). • The quantity ordered is too low (less than 1). • The quantity ordered is too high (more than 5,000). Create a class that stores an array of usable error messages; save the file as DataMessages.java. Create a DataException class; each object of this class will store one of the messages. Save the file asDataException.java. Create an application that prompts the user for a part number and quantity. Allow for the possibility of nonnumeric entries as well as out-of-range entries, and display the appropriate message when an error occurs. If no error occurs, display the message “Valid entry”. Save the program asPartAndQuantityEntry.java.
