called , designed to be thrown
when an improper designation for a document is encountered
during processing. suppose in a particular business all documents
are given a two-character designation starting with either u, c,
or p, standing for unclassified, confidential, or proprietary. if a
document designation is encountered that doesn’t fit that description,
the exception is thrown. create a driver program to test the
exception, allowing it to terminate the program.

The use of phrases, fragments, and punctuation can influence the mood of a passage; keeping this in mind, how would you describe the mood of the followingpassage? "fog on the essex marshes, fog on the kentish heights, fog creeping into the cabooses of collier-brigs; fog lying out on the yards, and hovering in the riggingof great ships; fog drooping on the gunwales of barges and small boats. fog in the eyes and throats of ancient greenwich pensioners, wheezing by thefiresides of their wards; fog in the stem and bowl of the afternoon pipe of the wrathful skipper; fog cruelly pinching the toes and fingers of his shivering little'prentice boy on deck."
