Write a program that converts dates from numerical month/day/year format to nor- mal "month day, year" format (for example, 12/25/2000 corresponds to December 25, 2000). You will define three exception classes, one called MonthException, another called DayException, and a third called YearException. If the user enters anything other than a legal month number (integers from 1 to 12), your program will throw and catch a MonthException and ask the user to reenter the month. Similarly, if the user enters anything other than a valid day number (integers from 1 to either 28, 29, 30, or 31, depending on the month and year), then your program will throw and catch a DayException and ask the user to reenter the day. If the user enters a year that is not in the range 1000 to 3000 (inclusive), then your program will throw and catch a YearException and ask the user to reenter the year. (There is nothing very special about the numbers 1000 and 3000 other than giving a good range of likely dates.) See Self-Test Exercise 19 in Chapter 4 for details on leap years
