2. Complete the class code below and using only the main method, add code to make an EXACT COPY of the input file to an output file named copyOf_. For example, if we input the file named story.txt our class will make an exact copy of the file, but save it under the name copyof_story.txt public class CopyFile { public static void main(String[] args) { Scanner console = new Scanner(System.in); System.out.printIn("Enter name of the file to copy\nFileName --> "); // Your code here } } // end of CopyFile class

In Java Suppose you are given a text file that contains the names of people. Every name inthe file consists of a first name and a last name. Unfortunately, the programmer thatcreated the file of names had a strange sense of humor and did not guarantee thateach name was on a single line of the file. Write a program that reads this file ofnames and writes them to the console, one name per line.For example, if the input file (Names.txt) contains:Bob Jones FredCharles EdMarstonJeffWilliamsThe output should be:Bob JonesFred CharlesEd MarstonJeff Williams Sample Output:Enter the name of the input file:Names.txtBob JonesFred CharlesEd MarstonJeff WilliamsFile processing completed.
Create a file named Question.py and then create a class on it named Question. A Question object will contain information about a trivia question. It should have the following: A constructor, with the following parameters: 1 string to be the question itself (for example: "When was Cypress College Founded?"). A list of four strings, each a possible answer to the question (only one of them should be correct) An integer named 'answer': the index in the list of the correct answer. Example: if the third answer in the answer list is the correct one, the client should pass 2 to this parameter to signify the correct answer is in index 2. Overload the __str__ method. It should return a string made up of the question and the four possible answers. A ‘guess’ method, with an integer parameter. If the 'answer' attribute matches the int passed to 'guess', return True. Otherwise, False On Main.py, in your main function, create a list and add four Question objects to it. You may give them with…

The expected output is in tabular format with 6 spaces between each column's value. // Program averages four numbers using static System.Console; class DebugSix02 { static void Main() { int[] numbers = {12, 15, 22, 88}; int x; int len=numbers.Length; double average; double total = 0; Write("\nThe numbers are..."); for(x = 0; x < len; ++x) Write("{0} ", numbers[x]); WriteLine(); for(x = 0; x <len; ++x) { total += numbers[x]; } average = total/len; Write("The average is {0}",average); } }
Integers numberOfParts, required Groups, and invalid Groups are read from input. If numberOfParts is 21 or more, then add 3 to requiredGroups. Otherwise, add 6 to invalidGroups. ► Click here for examples 3 public class GroupSurvey { 4 public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int numberOfParts; int requiredGroups; I int invalidGroups; 345679 8 9 10 11 12 13 14 15 16 17 18 19 20 } numberOfParts = scnr.nextInt (); requiredGroups = scnr.nextInt (); invalidGroups = scnr.nextInt (); /* Your code goes here */ if(numberOfParts>21){ requiredGroups= System.out.println(requiredGroups); System.out.println(invalidGroups);

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. Show what your new text file looks like after the append
The following sample file called grades.txt contains grades for several students in an imaginary class. Each line of this file stores a student's name followed by their exam scores.

Write a program that reads a list of enrollments from a file and prints a class roster for the teacher. Make the class roster line up as neatly as you can and still fit on the screen. You can choose the actual values to use for your data. Make sure to do enough sets of data to well test your program! (Empty data set, normal data set, data with large values, data with short values, etc.) Also, your program can't know ahead of time how many people are enrolled in the class... Don't forget to read the file's name from the user and protect your program against any errors that may occur during the opening of the file. Try to use functions to break up the program into more manageable pieces. USING C++ As an example, you might have the data file contain:
