Java provides a mechanism that enables a program to be executed from the command line, as an application. Java runtime execution works on the basis that the class executed must have a: (constructor? inner class? method?) named `main’ that is: (final? static? local?) , public and void. This should take an : (StringBuffer? ArrayList? Array?) of Strings as its only argument. Execution is begun by (calling this method? clicking the BlueJ Run button? selecting this method from the dropdown menu?) .

Write a C#program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate. Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string) ClassRegistration -...

Design a non-static method that can be contained within an instance/object of the MyCallback delegate type. This method should display values of two data fields contained within the object that is passed to the method. Make-up your own method definition that meets these requirements.

java programming I have a Java program with a restaurant/store menu. Can you please edit my program when displaying the physical receipt? I would like the physical receipt to export as text file, not print the console's order receipt. import java.util.*; public class Restaurant2 { publicstaticvoidmain(String[] args) { // Define menu items and pricesString[] menuItems= {"Apple", "Orange", "Pear", "Banana", "Kiwi", "Strawberry", "Grape", "Watermelon", "Cantaloupe", "Mango"};double[] menuPrices= {1.99, 2.99, 3.99, 4.99, 5.99, 6.99, 7.99, 8.99, 9.99, 10.99};StringusersName; // The user's name, as entered by the user.ArrayList<String> arr = new ArrayList<>(); // Define scanner objectScanner input=new Scanner(System.in); // Welcome messageSystem.out.println("Welcome to AppleStoreRecreation, what is your name:");usersName = input.nextLine(); System.out.println("Hello, "+ usersName +", my name is Patrick nice to meet you!, May I Take Your Order?"); // Display menu items and...

6. Design a Java class with a main method that does the following. You must include a meaningful comment for main and each method a. Main invokes a method readScores to read input from a file (name of your choice) that contains the name of the bowlers (no more than 25) and their bowling scores (two scores per bowler). The program stops reading values when it has reached the end of the file. For example, the file might contain: Bob 203 176 Jane 210 253 Jack 300 189 Eileen 220 298 • As the method reads the data, it stores the name into a String array and the average of the two bowling scores into an array of double. • The method returns the actual number of bowlers read in b. Main then invokes a method computeOverallAvg to: compute (a) the overall average score of all the bowlers combined, (b) the average score and name of the bowler with the highest average score and (c) the average score and name of the bowler with the lowest average scores. print to the console (a) the overall average...

Using python: (see attached- I need help with part Q2) Add a method to the person class name it (username) that takes the email and take off all the part from @ and after, and assigns the string before the @ sign to a variable username. For example: malabdullah@UT.edu, the method will assign 'malabdullah' as the username.

Write a program to test the Book class using C++. Create objects and use the print function in the objects to display information.

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

Write all the code within the main method in the TestTruck class below. Implement the following functionality. Construct two Truck objects: one with any make and model you choose and the second object with gas tank capacity 10. If an exception occurs, print the stack trace. Print both Truck objects that were constructed. import java.lang.IllegalArgumentException ; public class TestTruck { public static void main( String[] args ) { // write your code here

In C++ Create a new project named lab8_1. You will be implementing two classes: A Book class, and a Bookshelf class. The Bookshelf has a Book object (actually 3 of them). You will be able to choose what Book to place in each Bookshelf. Here are their UML diagrams Book class UML Book - author : string- title : string- id : int- count : static int + Book()+ Book(string, string)+ setAuthor(string) : void+ setTitle(string) : void+ print() : void+ setID() : void And the Bookshelf class UML Bookshelf - book1 : Book- book2 : Book- book3 : Book + Bookshelf()+ Bookshelf(Book, Book, Book)+ setBook1(Book) : void+ setBook2(Book) : void+ setBook3(Book) : void+ print() : void Some additional information: The Book class also has two constructors, which again offer the option of declaring a Book object with an author and title, or using the default constructor to set the author and title later, via the setters . The Book class will have a static member variable...

Can you please help me with this, its in java. Thank you. Write classes in an inheritance hierarchy Implement a polymorphic method Create an ArrayList object Use ArrayList methods For this, please design and write a Java program to keep track of various menu items. Your program will store, display and modify salads, sandwiches and frozen yogurts. Present the user with the following menu options: Actions: 1) Add a salad2) Add a sandwich3) Add a frozen yogurt4) Display an item5) Display all items6) Add a topping to an item9) QuitIf the user does not enter one of these options, then display:Sorry, <NUMBER> is not a valid option.Where <NUMBER> is the user's input. All menu items have the following: Name (String) Price (double) Topping (StringBuilder or StringBuffer of comma separated values) In addition to everything that a menu item has, a main dish (salad or sandwich) also has: Side (String) A salad also has: Dressing (String) A sandwich also has: Bread type...

Java programming - please see attched image for initial instruction before the following below. Write a subclass of VowelSeparator that adds three additional methods and a constructor. The class should be named VowelSeparatorAndCounter. Here are the methods to add: void setString(String s) This method should replace the string stored by the object with s. If the argument is null then the method should throw an IllegalArgumentException. (This is an unchecked exception) int getVowelCount() This method should return the number of vowels in the string.int getNonVowelCount() This method should return the number of characters in the string that are not vowels. Write a static method that accepts an array of VowelSeparatorAndCounter objects and returns the total number of vowels contained in all of them. It should have the following signature: public static int totalVowelCount(VowelSeparatorAndCounter[] a)
