required program java Create a class called DuplicateCounter. Create an instance method called count that takes a single parameter called dataFile (representing the path to a text file) and uses a Map of Strings to count how many times each word occurs in dataFile. The counts should be stored in an instance variable called wordCounter. Create an instance method called write that takes a single parameter called outputFile (representing the path to a text file) and writes the contents of wordCounter to the file pointed to by outputFile. The output file should be overwritten if it already exists, and created if it does not exist. Create a separate class called Application that contains a main method which illustrates the use of DuplicateCounter by calling both the remove and write methods. Your input file must be called problem2.txt and your output file must be called unique_word_counts.txt.

Ask the user for a filename. Display the oldest car for every manufacturer from that file. If two cars have the same year, compare based on the VIN. i am having trouble getting my code to work I have this code: import java.io.File; import java.io.FileNotFoundException; import java.util.ArrayList; import java.util.Scanner; class Car { String manufacturer; String model; int year; String vin; public Car(String manufacturer, String model, int year, String vin) { this.manufacturer = manufacturer; this.model = model; this.year = year; this.vin = vin; } public String getManufacturer() { return manufacturer; } public void setManufacturer(String manufacturer) { this.manufacturer = manufacturer; } public String getModel() { return model; } public void setModel(String model) { this.model = model; } public int getYear() { return year; } public void setYear(int year) { this.year = year; } public String getVin() { return vin; } public void setVin(String vin) { this.vin = vin; } } public class Demo {...

write a code in java

Write a Java program that accomplishes the same thing as the program in the pictures, except by using two dimensional arrays instead.

Write a class FileConverter with a constructor that accepts a String file name as its argument. It should store filename as its attribute (with a accessor getFilename(). The class should have the following methods: • createUpperCaseFile(): Accepts a String parameter targetFilename. It will open up both the file specified in class attribute filename and the method parameter targetFilename. Then it will convert all lines of the class attribute filename to upper case and write it to target file, line by line. • createRowCharCountFile(): Accepts a String parameter targetFilename. It will open up both the file specified in class attribute filename and the method parameter targetFilename. Then it will count the number of chars in each line of the class attribute filename and write it to target file line by line. The class must come with a main() method, which will create an object instance and generate two target files based on the source file, one all upper case, and another row char count.

Java programming 1. Write the code to print out an individual customer’s information. Your code must read the customer from a file, populate the object, and display the data from the object. Customer customer = new Customer (); 2. Write the signature line for this method 3, Write the line of code to read a line from the file Assume the object has been populated with the proper values. Write the line of code that will print one of the properties in the customer object. Be sure to include a textual description, e.g. "Customer Name: "

Write an Election class, in python that is used to record votes.

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...

Create class Node in a file named Node.java. This class has the following properties: Public fields previous and next, pointing to the previous and next nodes in the list, respectively. Private field data, defined as a reference to an object of any type. Public constructor that takes the node’s data as an argument. Public function GetData() that returns the node’s data.

First, implement a python class called Student. This class should store 2 variables, name and grade. Later, implement a class called Classroom. The constructor of this class should input the list of students in this classrom. This class should also contain 3 methods, add_student, remove_student and calculate_stats. As the names suggest, add_student method should input a Student object and add that to its' already existing student list, remove_student must input a full name(string) and delete the student with the provided name(you can assume no 2 students have the same full name). Finally, calculate_stats method must calculate and print the following statistics of the grades: 1. The name of the student with highest grade and the grade itself. 2. The name of the student with lowest grade and the grade itself. 3. The average grade

JAVA PPROGRAM ASAP Please Modify this program ASAP BECAUSE IT IS HOMEWORK ASSIGNMENT so it passes all the test cases. It does not pass the test cases when I upload it to Hypergrade. Because RIGHT NOW IT PASSES 0 OUT OF 1 TEST CASES. I have provided the failed the test cases and the inputs as a screenshot. The program must pass the test case when uploaded to Hypergrade. import java.io.File;import java.io.FileNotFoundException;import java.util.Scanner;public class Main { public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); String fileName; System.out.println("Please enter the file name or type QUIT to exit:"); fileName = keyboard.nextLine().trim(); while (!fileName.equalsIgnoreCase("QUIT")) { File file = new File(fileName); if (file.exists()) { int wordCount = countWords(file); System.out.println("Total number of words: " + wordCount + "\n);...
