- Define a class named ComparableCirclethat extends Circle and implements Comparable. Draw the UML diagramand implement the compareTo method to compare the circles on the basis ofarea. Write a test class to find the larger of two instances of ComparableCircleobjects, and the larger between a circle and a rectangle.Create a parent class Person with one attribute age and one method greet() that prints out "Hello, world!". By default, the age is 20. Then create a subclass CollegeStudent that inherits from Person and has its own attributes School_Name and Major. Then create an object (a college student, his name is Harry, age is 21, School_Name is "Felician University", and Major is "Computer Science"), then let Harry say"Hello World!".Draw the UML class diagrams for the following classes: An abstract Java class called Person that has the following attributes: a String called idNumber a Date called dateOfBirth representing the date of birth. a String for name A class called VaccineRecord with the following attributes: an enum called type of VaccineType a Date called date a String called batchCode A class called Patient that extends the Person class and has the following attributes and behaviours: an ArrayList that contains VaccineRecord objects called vaccinationRecord a public method called vaccinate that takes a VaccineRecord with the following signature: public void vaccinate(VaccineRecord vaccineRecord); a public boolean method called isVaccinated that returns whether or not the Patient has had a vaccine.

- Modify the GeometricObject class to implement the Comparable interface and define a static max method in the GeometricObject class for finding the larger of two GeometricObject objects. Draw the UML diagram and implement the new GeometricObject class. Write a test program that uses the max method to find the larger of two circles, the larger of two rectangles.using java programmingFor a parking management system, use the Observer pattern to implement this interaction using Java and implement the three classes mentioned below. Implement a ParkingObserver that has the role of the Observer. The Observable classes (Subjects) will be the ParkingLots. It would be helpful if the notify method in the subjects (and update method in the observers) took a parameter, perhaps an object of type ParkingEvent, which could have fields including the lot, timeIn, timeOut (if relevant), and permit. The ParkingObserver should register with each ParkingLot and receive the messages. Once a car enters (in an entry-scan only lot) or leaves (in an entry-scan and exit-scan lot), then the ParkingObserver will be updated, and then can register the charge with the parking system via the TransactionManager’s park() method. Based on these requirements you should implement three actor classes in this interaction using java: TransactionManager, ParkingObserver and ParkingLot. 1. The…We have a parking office class for an object-oriented parking management system using java Add(implement) a method to the Parking Office class to return the collection of permit ids for a specific customer (getPermitIds(Customer)) using java I have attached two class diagrams with definitions of all related classes in our system (i.e car, customer, .....). N.B. Parking office methods in the class definition like register, getcustomer and addcharge have already been implemented, we just need an additional getPermitIds(Customer) method as mentioned above Explain your code in a few words Important- We have a method to return a collection of permit ids (getPermitIds), what we need is a method to return the collection of permit ids for a specific customer (getPermitIds(Customer))
- Implement a new class that implements Comparatorof GregorianCalendar class to be able sort the calendar in increasingorder based on day, month, and year, in that order. Write a method to displaythe GregorianCalendar instance in “dd-MMM-yyyy” format usingSimpleDateFormatclass. Write a test program with 10 GregorianCalendarinstances and display the results after the sort.We have a parking office class for an object-oriented parking management system using java Add (implement )a method to the Parking Office c to return a collection of customer ids (getCustomerIds) using java I have attached two class diagrams with definitions of all related classes in our system (i.e car, customer, .....). N.B. Parking office methods in the class defination like register, getcustomer and addcharge have already been implemented, we just need an additional getcustomerID method as mentioned aboveUSING 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.
