10) In the system from the previous question, each job has a payload, which is the array of numbers that will be tested in the equipment and the e-mail to which the results will be sent after the job is finished. There are two types of jobs: Linear Testing, in which each number of the array is tested in sequence; and Random Testing, in which the numbers are tested in random order. Use the Command design pattern for representing the Jobs. Draw a UML diagram. Answer:

- Design and implement a data class. The class will store data that has been read asuser input from the keyboard (see Getting Input below), and provide necessary operations. As the data stored relates to monetary change, the class should be named Change. The class requires at least 2 instance variables for the name of a person and the coin change amount to be given to that person. You may also wish to use 4 instance variables to represent amounts for each of the 4 coin denominations (see Client Class below). There should be no need for more than these instance variables. However, if you wish to use more instance variables, you must provide legitimate justification for their usage in the internal and external documentation. Your class will need to have at least a default constructor, and a constructor with two parameters: one parameter being a name and the other a coin amount. Your class should also provide appropriateget and set methods for client usage. Other methods may be provided as…You will create Cart class as a context class to get total price and add product.◦ To implement Strategy pattern, depending on the country of shipping, the relevant customsduty is charged and the shipping cost of Europe Shopping, America Shopping increases. Largeproducts (XL-size) have an additional charge. Create AmericaShopping and EuropeShoppingconcrete class.In the USA, the duty tax is 1% and the base delivery fee is $15. In America, an additional taxdifferent from the customs tax is applied and this tax is 0.75%. Customs duty should be addedto the item fee for each item.In Europe, the customs duty is 1.5% and the base delivery fee is £11.In America, $5 should be added to the shipping fee when each item is added. But if the addedproduct size is XL, $10 should be added to the shipping fee. In Europe, this should only be doneif the product size is XL.Read the following scenario: To implement an exam, an instructor first notifies the students of the exam date and the topics to be covered. The instructor will prepare the exam paper, gets it copied to produce enough copies for the class, and hands it out to students at the designated time and location. The students attempt their answers to exam questions and hand in their answer papers to the instructor. The instructor then gives the answer papers to the tutor, along with sample solutions to each question, and gets them to mark it. The tutor will then records all the marks and return the answer papers to the students. After the answer papers have been returned to the students, they can raise any issues or queries about the marks they received. The instructor then reviews these queries/issues and decides whether marks adjustments are needed. If there are marks adjustments, the instructor will request the tutor to make the necessary changes in the marks record. Draw a sequence diagram…
- AVA code OVERVI EW This is a review exercise, so the primary goal of the exercise is to get your mind working and in the correct space.In this activity you will create a imaginary grid of locations that goes from −?≤?≤?, −?≤?≤?, with the coordinate (0,0) being "home". On this grid you will keep track of various animal objects as they move around the grid. Make sure that all animals stay within that grid at all timesincluding when they are created. Zwill be the map size and will control the highest number allowed on themap before wraping around. Using Java, create the following classes and primary program that uses the classes that you developed. INS T RUCT IONS Create the following classes. A N I MA L C LA SS Create an Animal class. Each animal has a name, an x and y integer coordinate. The Animal class should have at minimum the following methodsbelowbut you may want to add more if necessary: Also note, everyanimal will need to have to have “z”passed to it so that it knows how big the…Consider writing a program to manage a collection of movies. There are three kinds of movies in the collection: dramas, comedies, and documentaries. The collector would like to keep track of each movie's title, the name of its director, and the year the movie was made. Some operations are to be implemented for all movies, and there will also be special operations for each of the three different kinds of movies. How would you design the class(es) to represent this system of movies? Your design should implement the concept of OverridingModify the script RollDie.py that we provided with this chapter’s examples to simulate rolling two dice. Calculate the sum of the two values. Each die has a value from 1 to 6, so the sum of the values will vary from 2 to 12, with 7 being the most frequent sum, and 2 and 12 the least frequent. The following diagram shows the 36 equally likely possible combinations of the two dice and their corresponding sums: If you roll the dice 36,000 times: • The values 2 and 12 each occur 1/36th (2.778%) of the time, so you should expect about 1000 of each. • The values 3 and 11 each occur 2/36ths (5.556%) of the time, so you should expect about 2000 of each, and so on. Use a command-line argument to obtain the number of rolls. Display a bar plot summarizing the roll frequencies. The following screen captures show the final bar plots for sample executions of 360, 36,000 and 36,000,000 rolls. Use the Seaborn barplot function’s optional orient keyword argument to specify a horizontal bar plot.…
- Design and implement a class called RandomArray, which has an integer array. The constructor receives the size of the array to be allocated, then populates the array with random numbers from the range 0 through the size of the array. Methods are required that return the minimum value, maximum value, average value, and a String representation of the array values. Document your design with a UML Class diagram. Create a separate driver class that prompts the user for the sample size, then instantiates a RandomArray object of that size and outputs its contents and the minimum, maximum, and average values.Hello! I am new to Java and am struggling heavily with a current assignment. I got the output to look as desired, but the respective GPA is not functioning at all. My logic is to convert each letter grade into a number and multiply that by credit hours in that class. I will then add the result of this calculation for each class together and divide it by the total number of credits the student is undertaking. I have included images of the criteria model output (white) compared to my own (grey). I should add that we are intended to use a "do while" loop, but I could not get mine to break, which is why I added an additional break statement. import java.util.Scanner;public class GpaCalculator {public static void main (String args[]){Scanner inKey = new Scanner (System.in);double gpa = 3;String letInput = "";int grade = 0,earned = 0,finHrs = 0;String outResult = "";int hourInput = 0;do {System.out.println("What letter grade do you have in this Class?

The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 miles
- Create a new project named lab10. You will be implementing two classes: A SolarSystem class, and a Planet class. The SolarSystem contains Planet objects stored in a vector. A UML diagram for the Solar System and Planet classes The first part you should implement is the Planet class. Don't add the SolarSystem files to the project at the beginning, just work on the Planet class. Test the different overloaded operators as we did during lecture for your Planet class, and then move on to the SolarSystem class. The SolarSystem default constructor should resize the vector to zero. The default constructor values for Planet can be whatever you’d like, but make the mass a very small number, so later on when you're looking for the largest planet, it doesn't use the default Planet value. The addPlanets() method will take a number as an argument for the number of Planets that will be in your SolarSystem. So if you call addPlanets with 5 as an argument, there will be 5 Planets to add to the…In C# using an array Implement the inventory manager class. This class must have methods that do the following: Add a new item to the inventory manager. Remove an item from the inventory manager. Re-stock an item in the inventory manager. Display the items in the inventory manager. Search for an item in the inventory manager by at least two criteria (name, price, quantity, etc.). Test the inventory manager class with a driver program or unit tests. This may be a console application.Java Script There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) → 1 remainder(3, 4) → 3 remainder(-9, 45) → -9 remainder(5, 5) → 0 Notes The tests only use positive and negative integers. Don't forget to return the result.
