To allow a class to be written to a file all at once, we implement the _____class.
Step by step
Solved in 2 steps
- The functionality of each file is described below:Class BankAccount This class has two instance variables:namebalanceCreate a constructor that takes two parameters to initialize the instance variables name and balance. The name must not be an empty string. The name also must not include any numbers or symbols. The balance must be zero or more to be used.If the name was an empty string a Value Error will be raised with the message “name cannot be empty”If the name contained numbers or symbols a Value Error will be raised with the message “name cannot include numbers or symbols”If the name was valid, it will be formatted properly and assigned to the instance variable. The valid name consists of alphabetical characters lowercase or upper case, may include space, underscore or hyphen.The name may consist of first, middle and last name.One way to validate the name is using Regular Expressions.Proper name format is the first character uppercase and the rest of the name lowercase character.…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 JAVASCRIPT .xlsx parser I need to write a public class that reads an .xlsx file and returns an array of data in javascript.

- 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" ) );Write a back–end class called CSVFileLoader and save it in a file called CSVFileLoader.cpp. This class must have the following structure:Private MembersData Type Name Descriptionboolean cFileReadSuccessful This member will indicate if the file-read operation was successful. Private MethodsReturn Type Method Signature Descriptionint determineNumberOfColumns(string fileName) This method must determine the number of columns in the file.Insert a debug instruction that will display the number of columns as the method exits.void splitData(string line, TUTCell data[]) This method must split the line into separate elements and store each element in the data[] array.Insert a debug instruction that will display the data content of each element as it is inserted into data[] array.Public MethodsReturn Type Method Signature DescriptionTUTTable loadFile(string fileName, string subjectCode) This method must load the data of the file into a table object.

- Language/Type: Related Links: Author: Java file input Scanner Nick Troccoli (on 2017/04/25) Write a method named classPresidents that tallies votes for presidents of two school classes. Somehow the vote tallies for sophomore and junior class presidents got mixed up! Your method should accept as its parameter a Scanner representing a file of vote results. It should output the next sophomore and junior class presidents. The file format looks like the following: Jared s 25 Sophie j 12 Tom j 44 Isaac s 30 Emily s 60 Russ s 23 Madison j 20 The file repeats the pattern name year votes. The year is either "s" for sophomore or "j" for junior. Your program should output the candidate in each presidential race with the most votes, and how many votes they got. Specifically, if this file were named candidates.txt, your method could be called in the following way: Scanner input new Scanner (new File("candidates.txt")); classPresidents (input); The above call should produce the following output:…Attached Files: File Items.txt (119 B) Imagine we were creating a Textbased Adventure program and our Rooms in the assignment above could hold Items.

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%,…
