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)

Now we want to create an Object oriented System for a shopping mall. It has Items with name, manufacturer and price. Provide constructors. Getters, setters, toString methods. We add several items to Store. For that create a store class having name and arraylist of items, Provide Constructors, getters/setters and toString(), in addition you have to provide a method add which add new item to the array. The main function that does these things looks as follows: Public static void main(Strings[] args) { Item shampoo2(“pantene”, “Procter & Gamble”,100), noodles(“Noodles”, “knorr”, 50); // add further items. Store abcSuperStore; abcSuperStore.add(shampoo2); abcSuperStore.add(noodles); … abcSuperStore.sale(shampoo2); a bcSuperStore.sale(noodles);
Reuse your Car class . In a main, build an object of that class, and print out the object using System.out.println(). Notice that this simply reports the memory address of the object in question, and we’d like to do something more useful. To replace (or override) the toString (or equals) function. Now, build a toString function that prints out the make, model, and odometer reading for a vehicle object. public class Car { //instance variables private int odometer; private String make; private String model; //overloading //constructors public Car(int odometer,String make, String model) { this.odometer = odometer; this.make = make; this.model = model; } public Car(String make, String model) { this.make = make; this.model = model; } public Car(String make) { this.make = make; } /* *getter & setter methods */ public int getOdometer() { return odometer; } public void…
Implement the following tasks by using concepts of object-oriented programming (Java). i. Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.ii. The following is a short snippet of code that simulates rolling a 6-sided dice 100 times. There is an equal chance of rolling any digit from 1 to…
suppose there is a class Roster. Roster has one variable, roster, which is a list of tuples containing the names of students and their numerical grades- for example, [('Richard',90), ('Belle',67), ('Christine',85), ('Francine',97)]. Roster has a function findValedictorian that returns the name of the student with the highest grade. Find the valedictorian of the Roster object englishClass and store it in the variable valedictorian. using python
Question 2: Recall and apply the concepts of object oriented programming (Java).(i)Create a generic class with a type parameter that simulates drawing an item randomly out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to draw an item out of an empty box, it should return null. Write a main method that tests your class.
The Java Programming class has two types – remote and in-person. For remote students, the weighted score comprises of midterm, final, assignments and discussion. The weights for each are 30%, 30%, 30% and 10% respectively. For in-person students, the weighted score comprises of midterm, final and assignments. The weights for each are 30%, 30% and 40%. Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method…

I need to know how to do this in python: The base class Pet has attributes name and age. The derived class Dog inherits attributes from the base class Pet class and includes a breed attribute. Complete the program to: Create a generic pet, and print the pet's information using print_info(). Create a Dog pet, use print_info() to print the dog's information, and add a statement to print the dog's breed attribute. Ex: If the input is: Dobby 2 Kreacher 3 German Schnauzer the output is: Pet Information: Name: Dobby Age: 2 Pet Information: Name: Kreacher Age: 3 Breed: German Schnauzer
