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. Give the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.

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. Give the user the option to add new
appointments. The user must specify the type of the appointment, the description, and the date.

Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An appointment has a description (for example, “see the dentist”) and occurs on one or more dates. 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.

Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An appointment has a description (for example, “see the dentist”) and a date (use int's to store the 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. Additionally, you will need to implement a class called Calendar. This will contain an ArrayList of Appointment objects (The list is an instance variable of the Calendar class). You will need to provide the following methods for your Calendar class. A no argument constructor public Calendar(){...} This constructor will initialize your ArrayList instance variable to an empty list. /** * A method to add an appointment to the calendar * @param apt – the appointment object to add to the calendar. */ public void add(Appointment apt) {…} /** * A method to remove an appointment from the…
Write a Rectangle class. A Rectangle has properties of width and length. You construct a Rectangle object by providing the width and length in that order. If no width and length are provided to the constructor, construct a Rectangle with width 0.0 and length 0.0. We want to be able to get and set both the width and the length independently. We also want to be able to ask for the area of the rectangle and the perimeter of the rectangle. What will the object need to remember? width and length - those are the instance variables. Rectangle class has these constructors : public Rectangle() - Constructs a new rectangle with width and length of 0.0. public Rectangle(double width, double length) - Constructs a new rectangle with the given width and length. Remember that the job of the constructor is to initialize the instance variables. It has these methods. public double getWidth() - Gets the width of this Rectangle public double getLength() - Gets the length of this Rectangle public void…
When you add a contact to your phone, it automatically sorts those names alphabetically. In this exercise, we are going to create a phonebook that automatically sorts everytime a new number is added to the phonebook. A PhoneNumber class has been created already that has the instance variables name and number. Your job is to create the PhoneBook class that will store an ArrayList of PhoneNumbers. The PhoneBook class does not have a constructor - it only contains an ArrayList that can store the individual phone numbers that are added to it. There should be three methods in the PhoneBook class: addNumber- This method takes a PhoneNumber and adds it to the directory. Once the number has been added, the sort method is called on the directory to sort that new address into the phone book. sort- This method sorts the directory in alphabetical order A-Z.a. Remember that in order to compare Strings, we can use the compareTo() method. This returns an integer that indicates whether a String’s…
In this exercise, you are going to build on your Circleclass from the previous exercise. You are going to add 2 method, areaDifference and perimeterDifference. Both methods take a doubleradius of a second circle and return the difference from the current circle. For example, if you create a Circle object with a radius of 4 and call areaDifference(3), you will return the diffence between the area of a circle with radius 4 and the area of a circle with a radius of 3. perimeterDifferencewould be the same. Make sure you create at least one Circle and test and print the results of your methods. in java

Write a class that represents a player in a game. The player should have a name, password,experience points, an inventory array of four strings, and a location x,y. Your class shouldhave mutator and accessor methods for all variables. For example: setName(), getName(). Itshould have a suitable display method. Mutators and accessors should be public but allvariables should be private. To implement get inventory, use string * getInv(); Use the scoperesolution operator to implement larger methods such as display(). Use in class methods forshorter methods such as setName(), getName(). (in C++)Example:void setName(string name){this->name = name;}string *getInv();...string* player::getInv(){return inventory;}Note that in the above method setName “this->” is required for disambiguation. If writtenvoid setName(string n){name = n;}“this->” is not required.Write a test program that creates three players and displays them.Example Output:This program generates three player objects and…
check the Coin class and cointester program below. Write a new method .flipCoins(), that flips two (2) coins: the current coin and the coin passed as a parameter.

Instructions Below is a simple Book class. Every Book object has a title (a String) and a rating (an int). Make the Book class implement the Comparable interface. Book objects should be ordered by rating, and then (if the ratings are equal) they should be ordered alphabetically by title.
