- C# languageWrite a program to create a class employee, it consist of ID, name, department and address. All employees belongs to “Computer Science” department and it can never be changed by any means. Employee ID is initialized only once when Employee object is created, any further attempt to change ID should be failed. Class must have a 3 parameterized constructor to set values and two methods: print(): to display all the data of a particular employee totalObjects(): to count and print total number of objects that has been created In Main(), create atleast two objects of employee class, display their records by calling print() function and also print the total number of objects that has been created. [this question is continued on next page] Sample Main Method: static void Main(string[] args) { Employee obj1 = new Employee(1, "Zubair", "Karachi"); obj1.print(); Employee obj2 = new Employee(2, "Nabeel", "Islamabad"); obj2.print();…Writing the setbank functionsSetbalanceSetaccontIn order to enter the creditcard data instead of entering it into the constructor functionand execute it in the main class public class CreditCard { private String customer; private String bank; private String account; protected double balance; public CreditCard(String cust,String bk, String acnt,double initialBal) { customer=cust; bank=bk; account=acnt; balance=initialBal; } public CreditCard(String cust, String bk, String acnt) { this(cust,bk,acnt,0.0); } public String getCustomer() { return customer; } public String getBank() { return bank; } public String getAccount() { return account; } public double getBalance() { return balance; } // Update methods: public void charge(double price) { // make a charge balance += price; } public void makePayment(double amount) { // make a payment balance -= amount; }…employee and production worker classes write an employee class that keeps data attributes for the following pieces of information: • employee name • employee number next, write a class named productionworker that is a subclass of the employee class. the productionworker class should keep data attributes for the following information: • shift number (an integer, such as 1, 2, or 3) • hourly pay rate the workday is divided into two shifts: day and night. the shift attribute will hold an integer value representing the shift that the employee works. the day shift is shift 1 and the night shift is shift 2. write the appropriate accessor and mutator methods for each class. once you have written the classes, write a program that creates an object of the productionworker class and prompts the user to enter data for each of the object’s data attributes. store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen. satak overfallow
- 8. Circle ClassWrite a Circle class that has the following member variables:• radius: a double• pi: a double initialized with the value 3.14159The class should have the following member functions:• Default Constructor. A default constructor that sets radius to 0.0.• Constructor. Accepts the radius of the circle as an argument.• setRadius. A mutator function for the radius variable.• getRadius. An accessor function for the radius variable.• getArea. Returns the area of the circle, which is calculated as area = pi * radius * radius• getDiameter. Returns the diameter of the circle, which is calculated as diameter = radius * 2• getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * pi * radiusWrite a program that demonstrates the Circle class by asking the user for the circle’s radius, creating a Circle object, and then reporting the circle’s area, diameter, and circumference.…There are two types of data members in a class: static and non-static.
