Question

Please write in C# and create a UML design.

1. Create an Employee class. Items to include as data members are employee number, first name, last name, and monthly salary. Include default and overloading constructors , also include a method that calculates the annual pay of the employee, and a method to display the information of the employee. Create a second class to test your Employee class by instantiating two Employee objects and display all the above information of each individual.

using System.Threading.Tasks;

namespace EmployeeDetails
{
class Employee
{
public string fname,lname;
public int eno;
public double monthlySal, annualSal;

public Employee()
{
eno = 1;
fname = "Pravin";
lname = "Aute";
monthlySal = 50000;
}

public Employee(int no, string fnm, string lnm, double mpay)
{
eno = no;

lname = lnm;
monthlySal = mpay;
}
public void employeeInfo()
{
Console.WriteLine("Employee No : "+eno);
Console.WriteLine("Employee First Name : "+fname);
Console.WriteLine("Employee Last Name : "+lname);
Console.WriteLine("Employee Monthly salary : "+monthlySal );
}
public void calculateAnnualPay()
{
annualSal = monthlySal * 12;
Console.WriteLine("Annual Pay : "+annualSal );
}
}
class Test

{
static void Main(string[] args)
{
Console.WriteLine("Employee Object (DefaultConstructor) : 1");
Employee emp1 = new Employee();
emp1.employeeInfo();
emp1.calculateAnnualPay();
Console.WriteLine(Environment.NewLine );
Console.WriteLine("Employee Object (Parameterized Constructor) : 2");
Console.Write("Enter employee No : ");
int no = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter employee first name : ");
string fnm = Console.ReadLine();
Console.Write("Enter employee last name : ");
string lnm = Console.ReadLine();
Console.Write("Enter empployee monthly salary : ");
double msal = Convert.ToDouble(Console.ReadLine());

Employee emp2 = new Employee(no,fnm,lnm,msal );
emp2.employeeInfo();
emp2.calculateAnnualPay();

Console.ReadKey();
