Write a test program called TestSquare that: Creates two Square objects: one object with side’s length 5 and the other object with side’s length 5.75. Display the side’s length, area, and perimeter of each square object in this order.
use Pyhton. The tossball simulation we developed together in class is attached to this week's notes. Study it carefully to understand exactly what it is doing. It currently launches a ball in the main graphics window. You need to make the following changes and improvements and send me at the end your finished project in zipped folder format. Only python modules should be included. 1) Add a new class named "Cannon". This class it to represent the cannon that launches the balls. It should draw a rectangle (hint: use Polygon class from Graphics.py) at the launch point. Its width should be equal to the diameter of the balls that it shoots out and its length should be proportional to the speed, say something like speed * 0.15. The cannon should also be directed in the same direction that the balls shooting. Add proper width, height, and angle attributes to the class for supporting the settings above. The balls should start from the bottom of the cannon and be projected out through the…

In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…
This project utilizes three new classes: · Word - an immutable class representing a word · Words - a class representing a list of Word objects · WordTester - a class used to test the Word and Words classes. WordTester (the application) is complete and only requires uncommenting to test the Word and Words classes as they are completed. The needed imports, class headings, method headings, and block comments are provided for the remaining classes. Javadocs are also provided for the Word and Words classes. Word The Word class represents a single word. It is immutable. You have been provided a skeleton for this class. Complete the Word class using the block comments, Javadocs, and the following instructions. 1. Add a String instance variable named word which will contain the word. 2. Complete the one parameter constructor to initialize the word instance variable. 3. Complete the getLength method to return the number of characters in the…
i need it in util.java.scanner form and can you make it so i can copy and past it please thanks A regular triangle is one for which all sides are congruent and all interior angles. Create a class RegularTriangle with a field side (int) Create a constructor which accepts an int parameter and will assign the parameter to field side Create assessor and mutator for this class Create a method getPerimeter() which should return 3*side;
Using JAVASCRIPT write an object prototype for a Person that has a name and age, has a printInfo method, and also has a method that increments the persons age by 1 each time the method is called. Create two people using the 'new' keyword, and print both of their infos and increment one persons age by 3 years. Use an arrow function for both methods */ // Create our Person Prototype // Use an arrow to create the printInfo method // Create another arrow function for the addAge method that takes a single parameter // Adding to the age
Given the enum below, write Kotlin code that will either output "Primary Color", or "Secondary Color". You don't need a full program/method, just a code snippet. For this problem, Primary Colors are Red, Green, and Blue. Anything else is a Secondary Color. dnum class Color { Red, Green, Blue, Yellow, Purple, Orange
19 We have been dealing with colors as tuples or lists. We could also create a Color class. This would allow us to create new color objects and pass them around. For each method below, write and implementation that matches the content of the method docstring. Recall that individual color channels must have a value between 0 and 255. class Color: """ This class provides a representation of a color """ definit_(self, red, green, blue): Initialize the color with red, green, and blue values 663939
Write a class 'Cylinder' that has two fields: height and radius. The class should have only one parameterized constructor function to initialize these fields. The class should also have a method 'getVolume()' to calculate the volume of this cylinder. Now, create any 2 objects of this class with arbitrary values and show their volumes.
Create a class called Mather with a main method.Create an int width = 7. Create an int height = 6.Create the output below. Use Java arithmetic, do not just type in the numbers (hint, make use ofslide 2-59 and use parenthesis for math if you need to).While not required, try to use String constants instead of raw text for output (ie, “The area is: “).You can do this assignment iteratively. First, create that output. Then, extract each text messageinto a String, making sure the program still works correctly.Output:The area is: 42Width plus height is: 13Width modulus height is: 1Width divided by height is: 1
