PP 11.1 Design and implement a program that creates an exception class
called StringTooLongException , designed to be thrown when
a string is discovered that has too many characters in it. In the
main driver of the program, read strings from the user until the
user enters "DONE" . If a string is entered that has too many char-
acters (say 20), throw the exception. Allow the thrown exception
to terminate the program.
PP 11.2 Modify the solution to PP 11.1 such that it catches and handles
the exception if it is thrown. Handle the exception by printing an
appropriate message, and then continue processing more strings.
