What is Static Class and what is the use of Static Classes.

What's static classes and why we use Static classes.That's a question that always confuse beginner developers.

Static Classes are those classes that can call without creating the object of classes.Like if you have one class like FareSearch   and we have a one method like: BookMyFlight that we have declared Static  .we have declared this method static Because  with the help of this we can call BookMyFlight without creating a object of FareSearch .

I will give you one example that you can see run On Visual Studio.

using System;

class FareSearch

{

public static void BookMyFlight()

{

Console.WriteLine("I Am Static Class");

}

public void GetFlights()

{

Console.WriteLine("Air India");

}

}

class EntryPointclass

{

public static void Main()

{

FareSearch.BookMyFlight(); //you can do this bcs it is static method

//FareSearch.GetFlights();  //You Can't do this it will give an error bcs it is non-static field

}

}

Bcs When application starts all static field loaded by machine .

Static class is useful when you want to use any field and method periodically again and again in the whole application.
