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

Question 1 Write a Java program that prompts the user to enter a file name. Then the program counts and displays the number of letters and words in the file. You may use the following code fragment to extract and count the letters and words. int charchterCounter - 0; int wordsCounter - 0; String line; Scanner fileContent while (fileContent.hasNext ()) { line = fileContent.nextLine (); if(line.trim ().length () > 0) wordsCounter = wordsCounter + line. split (" ").length; for (int i - 0; i < line.length (): i++) if (Character.isLetter (line.charAt (i))) charchterCounter++
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.
Using the provided Book class in the file hw05_q2.py, create a container class called ShoppingList to store a list of books for a semester's worth of classes. Your ShoppingList class should primarily consist of a list of Book objects and should support the following methods: Constructor that takes a list of course designators (eg., "CSCI 1133") and creates a list of Book objects using the provided constructor in the Book class and the book information in the file catalog.py. Your constructor should have the signature __init__(self, courses). Overloaded addition operator that allows you to add Book objects to a ShoppingList using '+' Overloaded subtraction operator that allows you to remove Book objects from a ShoppingList using '-' A get_total_price() function that returns a sum of the prices of all books on the shopping list. You should use the same catalog list for testing as you used in problem 1. Save your ShoppingList class in the same hw05_q2.py file as the provided Book…
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…

Write a complete Python program that opens a file called sample.txt for reading, and opens a file called out.txt for writing.
For this assignment you are requested to write a program for the following scenario: • Build a program for a market, in the market we have items and each contains of three values (Item Name, Item Price, Item Expire Date). • The item values comes from a file each specification of the item is separated by (: ). • Must put the products that comes form the file into an array of object. • The program must check each product expire date if there is any products that expires in one month should notify the user as the output. • The expire checker process must be done on the array of object not directly from the file. NOTE: you can add only the month of the expiration date instead of adding full date (coffee:5000:August) and you can enter April as current month and then check the expiration.
For this assignment, your program will read characters from a string for the purpose of assigning data from that string to the private data members of a class. This simulates a program that would read a record in from a stored file into memory for the purpose of making changes to that record. Below is a template of your program. For this assignment, you MUST use loops (100 pts off if not using loops) and you cannot use the following methods: indexOf() substring() subsequence().
