Notice that variables have been declared for you. Write the simulated housekeeping() method that contains input statements to retrieve a yearString, a monthString, and a dayString from the user. Add statements to the simulated housekeeping() method that convert the String representation of the year, month, and day to ints. Include the output statements in the simulated endOfJob() method. The format of the output is as follows: month/day/year is a valid date. or month/day/year is an invalid date. Execute the program entering the following date: month = 5, day = 32, year =2014 Observe the output of this program. Execute the program entering the following date: month = 9, day = 21, year = 2002 Observe the output of this program.
