![Blurred answer](/static/compass_v2/solution-images/blurred-answer.jpg)
- design a class named Rectangle to represent a rectangle. The class contains: ▪ Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height. ▪ A no-arg constructor that creates a default rectangle. ▪ A constructor that creates a rectangle with the specified width and height. ▪ A method named getArea () that returns the area of this rectangle. ▪ A method named getPerimeter () that returns the perimeter. Draw the UML diagram for the class then implement the class. Write a test program that creates two Rectangle objects-one with width 4 and height 40, and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order.Tests: In the test_sun.py module, create tests for the planet objects. You can (and should) do this before you have written any Planet code at all. Implementation: In the sun.py module (see template), implement a Sun class as described in Section 10.4. Your Sun class should include the following methods: __init__, get_mass, get_radius, get_temperature, and __str__. Your __str__ method should include the following information for each planet: Name, distance from sun, radius, and mass. section 10.4Tests: In the test_sun.py module, create tests for the planet objects. You can (and should) do this before you have written any Sun code at all. Implementation: In the sun.py module (see template), implement a Sun class as described in Section 10.4. Your Sun class should include the following methods: __init__, get_mass, get_radius, get_temperature, and __str__. Your __str__ method should include the following information: Name, radius, mass, and temperature. You can assume that all numerical values are of type float and use type hints in all your method signatures accordingly.
- Correctly overloaded methods must have the same ______________________. a. identifier b. All of these. c. parameter list d. return typeCreate a class Rectangle. The class has attribute length and width, each of which defaults to 1. It has methods that calculate the perimeter and area of the rectangle. It has set and get methods for both length and width. The set method should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0. Write a program to test class RectangleWrite the following class. Complete the statement inside every mutator and accessor based on the following criteria: • setAcceleration ()- to increase the value of kmh by ten everytime it is invoked. • setDeceleration ()– to decrease the value of kmh by five everytime it is invoked. setBrake ()- to set the kmh to zero everytime it is invoked. getKmh ()– to return the value of kmh everytime it is invoked. public class YourNameCar { private double kmh; public YourNameCar () kmh = 0; public void setAcceleration () //complete your code here public void setDeceleration () //complete your code here public void setBrake () { //complete your code here public double getKmh () 7/complete your code here
- are a type of function that is defined in a class. A ________ key-value pair is a set of values associated with each other. _______ are variables that are defined within a method and are unique to a certain instance.Using Java!!Question 6 Write a Java class method createJSON () to return an object with type JSONObject which contains the following content: |{"schoolinfo" : { "school":[ {"tutitionfee":1323.5, "schoolname":"School A"}, {"tutitionfee":0, "schoolname":"School B"} 1, "title":"School Information" No import statements, no formatting., and no try-catch are needed.

Do not use chegg or any other site to code this.USING PYTHON Design a class named Triangle that extends the GeometricObject class. • Three float data fields named side1, side2, and side3 to denote the three sides of the triangle. • A constructor that creates a triangle with the specified side1, side2, and side3 with default values 1.0. • The accessor methods for all three data fields. • A method named getArea() that returns the area of this triangle. • A method named getPerimeter() that returns the perimeter of this triangle. • A method named __str__() that returns a string description for the triangle. For the formula to compute the area of a triangle, see Exercise 2.14. The __str__() method is implemented as follows: return "Triangle: side1 = " + str(side1) + " side2 = " + str(side2) + " side3 = " + str(side3) Write a test program that prompts the user to enter the three sides of the triangle, a color, and 1 or 0 to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the…
