# Can an Abstract Class have a constructor?

Yes when we define a class to be an Abstract Class it cannot be instantiated but that does not mean an **Abstract** class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.

```
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks; namespace Learn{    public abstract class Employee    {        string name;        public string Name { get { return name; } }        protected Employee(string name)        {            this.name = name;        }    }    public class EmployeeName : Employee    {        public EmployeeName()            : base("Harsh Kumar Srivastava")        {         }        static void Main(string[] args)        {            EmployeeName obj = new EmployeeName();            Console.WriteLine(obj.Name);            Console.ReadLine();        }    }}
```
