(B) Add a class named Square.java Give it private attributes double side and String color Make a constructor with two attributes for assigning a value to side and color when the Square is instantiated. Add getter and setter methods for all of the attributes. • Add a method that returns the area of the shape.

1) Define a Person class containing two private attributes: last name, first name. Provide this class with a constructor allowing the initialization of its attributes and a method that displays the last name and first name of a person: void display (). 2) Define a Customer class inheriting from the Person class and having a private attribute: numidentity. Provide this class with a constructor allowing you to create a customer from their last name, first name and identity card number and a method: • void display() which displays the last name, first name and ID number of a customer. 3) Define an Owner class inheriting from the Person class and having two private attributes: name of the video club (nomclub), address of the club (adrclub). Provide this class with a constructor allowing to create a landlord from his name, his first name, the name of his video club, the address of his club and a method: • void display() who displays the name, first name, last name and address of his video…

Create a Point class to hold x and y values for a point. Create methods show(), add() and subtract() to display the Point x and y values, and add and subtract point coordinates. Create another class Shape, which will form the basis of a set of shapes. The Shape class will contain default functions to calculate area and circumference of the shape, and provide the coordinates (Points) of a rectangle that encloses the shape (a bounding box). These will be overloaded by the derived classes; therefore, the default methods for Shape will only print a simple message to standard output. Create a display() function for Shape, which will display the name of the class and all stored information about the class (including area, circumference and bounding box). Build the hierarchy by creating the Shape classes Circle, Rectangle and Triangle. Search the Internet for the rules governing these shapes, if necessary. For these three Shape classes, create default constructors, as well as constructors…

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.

B elow for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked.  It's important to implement the drivers to test and demonstrate…

write all the code necessary for a class  Toaster  as described here. A toaster  can be described as having a model (string), manufacture(string), and price. include the following methods in your class definition.(in java) 1. a default constructor2. an overloaded constructor takes the model and manufacture as input.3. an accessor method to acquire the price.4. a tostring method that returns a reasonable description of the toaster.

please solve it with java and put screenshots of the code

Answer with True or False for the following. Explain your answers.-It is legal to write a method in a class which overloads another method declared in the same.-It is legal to write a method in a superclass which overrides a method declared in a sub-class.

Please help me with this using java. Explain each line of code with comments. Please make sure that the code works.
