};
- Implement a constructor that initializes new objects of date class to be set to the 1st of January 2000.
- Implement setters for day, month, and year.
- Implement the advance method, which moves to the next day, ensuring that all data members are updated appropriately.

Now, write a class Circle with private instance variables as radius and Pi (value is 3.14). Write public setter, getter for radius, Area method for calculating Area, Draw method for radius. Formula for calculating area=pi*r^2 Formula for calculating radius=Math.sqrt(xCordinate^2+yCordinate^2) Extend a Circle class from Point class such as Class Circle extends Point Write a Default constructor in Circle class that sets radius, xCoordinate&yCoordinate to some default value e.g. -1; Write a Parameterized constructor in Circle class which takes xCoordinate, yCoordinate and radius as a parameter.

Provide getters/setters and constructor also write an abstract method isOversize() .From this class derive two classes: book, which adds a page count (type int); and tape, which adds a playing time in minutes (type float). Each of the classes should have a getter/setters and constructors and provide definition to function called isOversize() to the book and tape classes. Let’s say that a book with more than 800 pages, or a tape with a playing time longer than 90 minutes (which would require two cassettes), is considered oversize. You can access this function from main() and display the string “Oversize” for oversize books and tapes when you display their other data. explain the working in your wordsImagine a publishing company that markets both book and audiocassette versions of its works.

- Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format.

It should have attributes of the child’s name and age ,the name of the child’s teacher ,and the greeting. It should haveappropriate accessor and mutator methods for each of the attributes. Derive a class ExaggeratingKid from schoolkid , as described above . The new class should override the accessor method for the age , reporting the actual plus 2. It also should override the accessor for the greeting ,returning the child’s greeting concatenated with the words “I am the best”.Implement the Seller class as a derived class of Person class. Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages.

- Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.Create a class Animal and Add a protected data member named id of integer type. Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0. Also provide parameterized constructor and toString method.

Reptile, Bird, Mammal Next create the three child classes which extends form Animal class. Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”.

The first of these classes is called dayType which will manipulate a day of the week. The class dayType will store a day, such as Sun for Sunday. The class should be able to perform the following operations on an object of type dayType: a. Set the day. b. Print the day. c. Return the day. d. Return the next day. e.…
