This is a Java exercise, please help me with the question ASAP, I would upvote your answer.

Write a method OccursOn inside each of the sub classes that checks whether the appointment occurs on that date (OneTime), day (Day) or month (Month). Ask the user to enter a date to check (for example, 2006 10 5), and ask to user if they want to check against OneTime, Day or Month appointment. Based on what the user selected, OccursOn inside each of the sub class should run and display any matching appointment and associated descriptions.

For OneTime subclass, OccursOn need three inputs (Year, Month and Day) to validate, for Day subclass, OccursOn needs one input (Day) to validate, and for Month subclass, OccursOn need one input (Month) to validate. OccursOn is different for different subclasses.

18 23 19 24 20 25 21 26 55 P9.1 Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An appointment has a description (for example, "see the dentist") and a date. Write a method occursOn(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Then fill an array of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. 22 2 23 24 25
