- Edit only the class definition. DO NOT CHANGE the code given under 'main' please. Steps: Additionally implement any Python Magic/Dunder methods such that instances of the class minimally:1. Support addition, subtraction, equality operations and the built-in abs function2. Are Iterable i.e., support for loops and star arguments for unpacking into function calls3. Support a string representation that displays the class name and coordinates stored by the instance: i.e. for an object initialized as: Vector(0, 3), the string representation should be ‘Vector(0, 3)’The code given under main tests for each of the program requirements and subsequently uses the turtle module to plot randomly generated points rotated. A screenshot for a sample run of the program is attached. Template.py: from math import hypot, pi from random import uniform import turtle as t class Vector2D: ... if __name__ == '__main__': # Test Vector class a, b = Vector2D(0, 3), Vector2D(0, -3) tests =…(YOU ARE NOT ALLOWED TO USE ARRAYLIST IN THIS PROJECT)Write a Java program to simulate a blackjack game of cards. The computer will play the role of the dealer. The program will randomly generate the cards dealt to the player and dealer during the game. Cards in this game will be represented by numbers 1 to 13 with Ace being represented by a 1. Remember, that face cards (i.e. Jack, Queen, and King) are worth 10 points to a hand while an Ace can be worth 1 or 11 points depending on the user’s choice. The numbered cards are worth their number value to the hand.Can you please show b and c. I know the answers are 118.5 ATP and 114.5 ATP but I can not get those answers
- Trace through (show all the steps as we did in class) for the following java code for the factorial function. Show all the steps (illustrate, do not code) that lead to the final answer when myFactorial(6) is called: int myFactorial( int integer) { if( integer == 1) return 1; else { return(integer*(myFactorial(integer-1); } }(CLO3) Read the following description and answer the following questions about it: Problem Description: A car dealership allows customer to purchase their new cars with different options. At this time, those options are color, model, and air condition, as shown below in class CustomerOrder. Of course, the dealership wants the software to be flexible enough to be able to add more options in the future, if needed. CustomerOrder -carColor: String -carModel: String -hasAirCondition: boolean Q1) Write the full required code in Java to use the Builder design pattern to create class CustomerOrder. Q2) Write a Java main() method to create an object of class CustomerOrder with color "red" and without air condition.For this discussion, we are going to be working with operators. Below is the code for the Operators class, which contains a main() method and a divisible() method. Study the code below, paying special attention to the four if statements. First, explain using complete sentences how each if statement evaluates (true or false), as well as what takes place in each if statement's test (comparisons, function calls, increments/decrements, etc.). Then, provide what the program will output. public class Operators { public static void main(String[] args) { int a = 5, b = 10, c = 11; System.out.println("This program works with operators."); if (a < 10 ^ b == 10) System.out.println("Java "); if (divisible(b, a) | divisible(c, a)) System.out.println("Programming "); if (a + b - (++c) == c - (b--) + 1) System.out.println("CITC ");…
- F4DO NOT USE EXISTING ANSWERS ON CHEGG OR COURSE HERO OR ANY OTHER SERVICES PLEASE! Thanks :) CODE IN PYTHON AND SHOW COMMENTS TO EXPLAIN CODE A confused Dutchman trying to speak English could say “I am in the war”, even though there is no hostile activity going on. The confusion1 here is that the English sentence “I am confused” is translated in Dutch as “Ik ben in de war”, which is phonetically (“sounding”) quite close to the first sentence. Such confusion leads to much enjoyment, but can complicate matters a bit. Given a sentence in Dutch and a dictionary containing both correct translations as well as phonetic (incorrect) translations of individual words, find the translation of the sentence and indicate whether it is correct, or in case there is more than one find the total number of correct and incorrect translations. A sentence is correctly translated when each word of the sentence is correctly translated. Input The input consists of: One line with an integer n (1≤n≤20), the…Discussion: chapter 4 Pick a method of debugging/error catching and explain how it works and give a real world example of how it works.
- I am struggling with creating arrays program on eclipse. Struggling with getting the result as asked in assignment. Need help with problem a and b. Please help as soon as you can.Question: Your task is to find the number of ways that you can put those brackets in such a way that they will be always balanced after taking the n pair of brackets from the user in Java Language.[Fish Tank] You play with a clown fish that has an initial size so. The fish can eat other fish in a tank organized in m columns and n rows. The fish at column i and row j has a positive size si,j. When your fish eats another fish, it grows by that amount. For example, if your clown fish has a size of 10 and eats a fish of size 5, it becomes of size 15. You cannot eat a fish that is bigger than your size. The game starts by eating any fish in the first (left-most) column that is not bigger than yours. After that, you advance one column at a time by moving right. You have only three allowed moves. You either stay at the same row, move one row higher or one row lower. You will always move to the right. Thus, you will make exactly m moves to advance from left to right. Your goal is to exit the fish tank from the right with the biggest possible size. The figure below shows an example with the best answer highlighted. In this case, the final fish size is 71 (10+8+7+24+22). You are required…
