Override the toString() method to display the details of the rectangle, including its shape type, length, width, and area.

Inheritance

Create a base class called Shape with two final variables: PI and shapeType. PI should be set to 3.14159 and shapeType should be a String that indicates the type of shape.

Create a subclass called Circle that extends Shape. Circle should have an instance variable called radius and a constructor that initializes radius. Override the toString() method to display the details of the circle, including its shape type, radius, and area.

Create another subclass called Rectangle that extends Shape. Rectangle should have two instance variables called length and width, and a constructor that initializes length and width. Override the toString() method to display the details of the rectangle, including its shape type, length, width, and area.

In the main method, create objects of Circle and Rectangle and call their toString() methods to demonstrate inheritance and the use of final variables.

JAVA please help Design a class named Sandwich with data fields for description and price. Include a constructor that requires arguments for both fields and a method to display the data (example value for description is chicken). Create a subclass named DeliverySandwich that inherits from Sandwich and has a delivery fee and a delivery address as additional fields. The description, price, and delivery address are required as arguments to the subclass constructor. The delivery fee should be set to $3 if the sandwich ordered costs more than $15; otherwise it should be set to $5. Write an application that instantiates at least two objects of each type and displays their state (data).
Inheritance – Create two abstract subclasses of AECar. Next create four additional subclasses. (Note: if you are having difficulty check out some online resources and see what categories of alternative energy cars exist.) Decide which properties should be pushed up into a super abstract class and which belong in the individual subclasses. You do not need to code every method – just place a stub placeholders
Polymorphism Create a class hierarchy that represents different types of employees in a company. Start with a class called Employee that has two methods: calculateSalary() and displayDetails(). Then, create two subclasses of Employee: Manager and Engineer. Override the calculateSalary() method in both subclasses to calculate the salary based on their job role and experience. Override the displayDetails() method in both subclasses to print out a message indicating the details of the employee. Next, create another class called Salesperson that extends Employee and has a method called calculateCommission(). Create two subclasses of Salesperson: SeniorSalesperson and JuniorSalesperson. Override the calculateCommission() method in both subclasses to calculate the commission based on their sales performance. Override the displayDetails() method in both subclasses to print out a message indicating the details of the salesperson. In the main method, create objects of each class and call their…
Develop the ‘Shape’ application such that: ‘Rectangle’, ‘Ellipse’, and ‘Triangle’ classes inherit from the ‘Shape’ class. Develop the ‘Square’ and ‘Circle’ class where ‘Square’ inherits from ‘Rectangle’ and‘Circle’ inherits from ‘Ellipse’. ‘Triangle’ has no derived class. For each class, implement the overridden methods ‘draw’, ‘move’, and ‘erase’. Eachmethod should only have an output statement such as “Rectangle – draw method”that will be displayed when the method is invoked. Implement the default constructors for each class with a corresponding message tobe displayed when invoked. No initializations are required; that is, the outputmessage will be the only executable statement in the constructors. Do not implement any other methods for these classes ( i.e., ‘toString’, ‘equals’,getters and setters ). Implement a ‘ShapeTest’ class which will instantiate an object of each class. Exercise each of the ‘draw’, ‘move’, and ‘erase’ methods of each class Remember to make sure that…

Java Object Oriented Programming Create a Shape class that shall have color and filled instance variables of enum Color and boolean type. The filled boolean variable shall show, whether the shape is filled (colored). The enum Color shall be defined within the class having 4 color names (choose any four). Also define getArea and getPerimeter method in Shape class, both shall return 0. Create Rectangle class with length and width attributes and a Circle class with radius attribute, of type double. Properly encapsulate all fields. Circle and Rectangle shall extend Shape class and override getArea and getPerimters methods as per its type and specific formula. In Test class, create an object of Rectangle and Circle, by initializing all attributes in constructor and print both shapes' area and perimters. In Test class, define a static method with following signature, public static void printEachShapeCount(Shape... shapes) As you know, the parent type variable can hold the…
(Java) The Sculpture Subclass Write class as follows: The class is named Sculpture, and it inherits from the Painting class. It has a private boolean member variable named humanForm It has a default constructor that assigns the values "No name" to name, "No artist" to artist, -1 to the year, "No medium" to the medium, and false to the humanForm variable. This default constructor calls the five argument constructor. It has a five-argument constructor to assign values to the name, artist, year, medium, and humanForm variables. It has a getter and setter for the humanForm variable. It has a toString() method. This class contains no other methods Make sure to include your name, the name of this class, our course number, and the Activity number in a Javadoc comment at the top. Make sure to write a Javadoc comment for each of these methods.

Create a base class called “Animal” which has two (2) class fields. The first field holds an integer “IDtag” for a number that a zoo uses to catalogue their animals and the second field holds a string called “species.”From the Animal class, derive two (2) classes. One is called “Bird” and the other “Reptile”. E.g. Species could be (for the Bird class) ostrich, dove, chicken etc. and (for the Reptile class) lizard, snake, bearded dragon etc.The Bird class has an additional class field called “colour” which holds the colour of the birds feathers (int – 1=grey, 2=white, 3=black). The reptile class has an additional class field called “bloodTemp” which hold the reptile’s temperature of their blood (double).You need to instantiate two (2) objects. The bird object will be called “brd” and the reptile object called “rept.”Input values for the bird’s IDtag, species and feather colour (int) and for the reptile’s IDtag number, species and bloodTemp. Override the Animal class’s input and output…

Part A Create a FitnessTracker class that includes three data fields for a fitness activity: a String for the name of the activity as activity, an int for the number of minutes spent participating as minutes, and a LocalDate for the date as date. Create a default constructor that automatically sets the activity to running, the minutes to 0, and the date to January 1 of the current year. Overload the constructor so it receives parameters for each of the fields and assigns them appropriately. Includes methods to get each data field. Part B Create an application that instantiates two FitnessTracker objects. Prompt the user for values for one object, and pass those values to the three constructor parameters. Retain the default constructor values for the other object. Display the values for each object. An example of the program is shown below: Enter activity >> swimming Enter minutes spent swimming >> 90 Enter month >> 2 Enter day >> 24 Enter year >> 2021…
