- Put the class definition in EV.h and the implementation of the constructors and functions in EV.cpp 1. Define a class called "EV", that represents the information of an electric vehicle. The EV is defined with these attributes: model (string), range(int), unit (string) and year (int). Functions of the EV class must perform the following operations: 1. A default constructor which sets all the numeric instance variables to zero. 2. A constructor with 4 parameters which sets the 4 instance variables to the corresponding values passed. 3. Implement a getter function for each of the 4 instance variables that will return the value of the instance variable. For example, the getX() function for the instance variable model must be called getModel(). 4. Implement a setter function for each instance variable that will assign to the instance variable to the value passed. For example, the setX() function for the instance variable model must be called setModel(). 5. An info function: this function…Computer Science In java design 2 classes, one where you design a Car object with 3 features, doors, windows and seats. Include one toString method that returns how much you have for each feature. This is NOT serializable, the file is .txt In the second class, create a client class, where you have an existing file, which already has 2 car objects in it, delete the second line with the car object, so there is only 1 and then write in the file 4 car objects from the Arraylist. DO NOT use colons ":" in your work . Explain all steps of your work and display an output. Don't use buffer reader or file reader. Use Scanner when reading a file, below are the imports you can use, YOU can also use any type of error message import java.io.FileWriter;import java.io.IOException;import java.io.PrintWriter; import java.util.Scanner here is a example of scanner if needed Scanner file = new Scanner( new File("flights.txt" ) );Computer Science JAVASCRIPT .xlsx parser I need to write a public class that reads an .xlsx file and returns an array of data in javascript. The array would be all of the data inside of the file. The file itself is going to be inside of a folder(downloadedFIles) inside of my project. So the public class will need to account for that.
- ReadInstructor. The class will: – Create an array of instructor objects – Read the instructors.txt file – Create an Instructor object for each line of input and store the object in the array. – After closing the file, it will print out a line for each instructor in the array.

- Python3 code: Create a simple text file called mycandy The first line of the file will be Candy Name, Candy Calories, Total Fat Grams Next, add five lines to the file by hand using your favorite five candy bars information. Each line's data will be separated by commas. Create a class called Candy which keeps track of the three pieces of information Read in the file line by line and create a Candy class instance for each candy bar you have, and add that new instance to a list. Once you have the list created, loop through the list and print the candy bar info out to the console Add a line of code to append one more candy bar’s information to your mycandy file.

- Modify the code below to create a "Favorite Video Game List" program that is contained in three files: Game.h Game.cpp Game_List.cpp You will need do to these things as you modify the code and put it into the three files: Create a class called "Game" (instead of "Movie") that contains 3 private variables ("title", "year", and "rating") The "year" is when the game first came out. The "rating" should be from 1 to 5 (5 being the best). Add the appropriate member functions of the class (setters and getters). Continue to use the get_title_upper() function as part of the class, Game, and in the output within the main file, Game_List.cpp. Add the Default Constructor for the class with the member functions of the class. Ignore the Destructor code for now. It's there to show you where it ends up in future code. Don't forget to add the include guard to the .h file Use the scope resolution operator correctly for each file. Don't use the "using namespace std;" for the main…Java Problem The teacher at a school needs help grading an exam with a number of True/False questions. The students’ IDs and test answers are stored in a file. The first entry of the file contains the answer to the test in the form: TTFTFTTTFTFTFFTTFTTF Every other entry in the file is the student’s ID, followed by a blank, followed by the students’ response. For instance, the entry: ABC54102 T FTFTFTTTFTTFTTF TF The student’s ID is ABC54102, answer to question 1 is True, the answer to question 3 is False. Also, the student did not answer question 2 and question 18. The exam has 20 questions. Here is the grading policy: each correct answer is awarded two points, each wrong answer get -1 point, and no answer gets 0 point. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score (total points), followed by the test grade. Assume the following grade scale will be used: 90%-100%, A; 80%-89.99%, B; 70%-79.99%,…In C++ code: Design and write a C++ class that reads text, binary and csv files.

A Call-Back is necessary for each file as each file requires different regular expressions to parse.
