Add a main method to the class that demonstrates class Date's capabilities.Computer Science Questionusing python language Suppose a call center has three levels of employees—respondent, manager, and director. An incoming telephone call must first be allocated to a respondent who is free. If the respondent cannot handle the call, the call must be escalated to a manager. If the manager is occupied, then the call should be escalated to a director. Design your own classes and data structures for this problem. Implement a method dispatchCall() that assigns a call to the first available employee.

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. Give the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.USING JAVA: Part A) 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, occuresOn(int year, int month, int day) The check whether the appointment occurs on that date. For example, for appointment, you must check whether the day of the month matches. This 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. Part B) Improve the appointment book by giving the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.
