Use the exception class MessageTooLongException of Self-Test Question 16 in a program that asks the user to enter a line of text having no more than 20 characters. If the user enters an acceptable number of characters, the program should display the message, “You entered x characters, which is an acceptable length” (with the letter x replaced by the actual number of characters). Otherwise, a MessageTooLongException should be thrown and caught. In either case, the program should repeatedly ask whether the user wants to enter another line or quit the program.
