2 part question I am using eclipse! Create a class Circle, which - has a field radius (double) It should have appropriate accessor and mutator. If the Circle instance is created without parameter, the radius should be set to 1.0. Otherwise the radius should be set to the specified value. The Circle class should have a class level (not instance level) field called Pi. Since Pi is a known constant (3.14159), this field should be a constant. This variable can be accessed directly by outside objects. This Circle class should have a getArea() method and getPerimeter() method. You need to decide their return value and access level. Note: Area = Pi * radius * radius Perimeter = 2 * Pi * Radius part 2 Create a subclass of Circle class ColoredCircle by implementing the ColoredShape interface. It should have a field color of type enum ShapeColor. ColoredShape.java ShapeColor.java ColoredCircle should have two constructors. One will takes one parameters radius and set the color to…
Write a graphical application that contains a class named RV whose objects are the recreational vehicle designed and digitized as described in Knowledge Exercises 20 and 21 (you can design your version as well. Simple car shape is will be appreciated. The class’s private data members should be the vehicle’s body color and (x, y) location. a) Give the UML diagram for the class. It should include a three-parameter constructor, a toString method, a method to input the values of all of an object’s data members, and a show method to draw the RV at its current (x, y) location. b) Progressively implement and test the RV class by adding a method and verifying it before adding the next method. A good order to add the methods to the class is the three-parameter constructor, followed by the toString method, the show method, and finally the inputmethod. The client code should create an RV object using the three-parameter constructor to test all of the methods as they are progressively added to the…
Please do it in JavaScript or C# 1) Design and implement the class structure for a drawing application. A drawing is made up of a canvas that contains a collection of three different shapes: circles, lines, and boxes. Each shape can be drawn by calling a Draw() method for that shape. The canvas class should also have a draw method that draws all of the shapes it contains. You don’t have to actually draw anything on a screen; you can simulate drawing by writing a message to the console.For example, the code snippet: canvas.Draw();Drawing a circle at...Drawing a line at...etc. (For each shape on the canvas) 2)(Bonus) Consider re-writing the above answer (#1) differently where the canvas does not contain the shapes, but is able to draw any of the three shapes passed to it. Re-design canvas.Draw() if you need to. Your main() program should ask for user input on what shape to draw. Ask once, draw, then exit.could produce something like the following output to the console:

1. Design a new Triangle class that extends the abstract GeometricObject class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.
please code in python Answer the following questions about this Dog class: [refer image for dog class] 1. Construct an instance of the Dog class whose name is Snickers and was born in2011 and assign that instance to a variable called myDog.2. Call the bark method so that myDog barks 3 times.3. Add a method to the Dog class called isPuppy that returns True if the dog is lessthan 1 year old.4. Add the __str__ method to the Dog class. It should return a string that includesthe dog’s name and age.
To determine if two objects in a class are equal, we should NOT use "==". We should override the _____ method of the Object class with our own definition of equality.
Write a class definition line and a one line docstring for the class Dog. Write an __init__ method for the class Dog that gives each dog its own name and breed. Test this on a successful creation of a Dog object.>>> import dog>>> sugar = dog.Dog('Sugar', 'border collie')>>> sugar.name'Sugar'>>> sugar.breed'border collie' Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully.>>> sugar.tricks[] Write a method teach as part of the class Dog. The method teach should add a passed string parameter to tricks and print a message that the dog knows the trick.>>> sugar.teach('frisbee')Sugar knows frisbee
1. Create a class called Elevator that can be moved between floors in an N-storey building. Elevator uses a constructor to initialize the number of floors (N) in the building when the object is instantiated. Elevator also has a default constructor that creates a five- (5) storey building. The Elevator class has a termination condition that requires the elevator to be moved to the main (i.e., first) floor when the object is cleaned up. Write a finalize() method that satisfies this termination condition and verifies the condition by printing a message to the output, Elevator ending: elevator returned to the first floor. In main(), test at least five (5) possible scenarios that can occur when Elevator is used in a building with many floors (e.g., create, move from one floor to another, etc.). Hint: Termination occurs when the instance is set to null. You may wish to investigate “garbage collection” for this exercise.
In this assignment, you will make two classes,Student and Instructor, that inherit from a superclass Person. The implementation of class Person is given below. public class Person{private String name;private int age; public Person(){name="";age=0;}/**Create a person with a given name and age.@param name the name@param age the age*/public Person(String name, int age){this.name = name;this.age = age;} /**Get the name.@return the name*/public String getName(){ return name;}/**Change the name.@param name the name*/public void setName(String name){ this.name = name;}/**Get the age.@return the age*/public int getAge(){ return age;}/**Change the age.@param age the age*/public void setAge(){ this.age = age;}/**Convert person to string form.*/public String toString(){return "Name: " + name + "\t" + "Age: " + age;}} You will also need to write a test program to test the methods you write for these two classes. The implementation details are described as follows. Stage 1:In the first file…
